This tutorial is about transcoding video fom one codec into another using FFMPEG. I got deeper into FFMPEG when I wanted to transcode into FLV (Flash Video) and it works very well. I developed the Riva FLV Encoder, a GUI for FFMPEG.
Update 26.10.2006: This tutorial is a little outdated as there were many changes in FFMPEG like the switch from CVS to Subversion and the workflow to compile FFMPEG under Windows has become more difficult. For the new tweaks check this tutorial.
- Download MinGW ” MSYS current releases (Window Exe Binaries MSYS-1.0.10.exe & MinGW-3.1.0-1.exe)
- Install MinGW
- Install MSYS
- HINT: During the Postinstall be sure to set the right path to MinGW with a “/” instead of a Windows-”". If you did it wrong anyway re-install MSYS to the same directory and do the postinstall right (I missed it a few times)
- Download and compile Lame
- Extract Lame to your MSYS home-directory
- Open MSYS and change to your lame-directory (cd ../lame-XXX)
- Enter the following commands:
./configure //(takes a few minutes) make //(lame is being comiled; takes a few minutes, too) make install
- After installing you will recognize that there are new directories and files in MSYS/local which we will use while compiling ffmpeg with mp3-support
- Download Subversion Client like Tortoise SVN (http://http://tortoisesvn.tigris.org/) and install it
- Check out the sourcecode from svn://svn.mplayerhq.hu/ffmpeg
- Compile FFMPEG
- Change the directory in MSYS to your ffmpeg-directory (cd ../ffmpeg)
- Enter the command:
./configure --enable-memalign-hack --enable-mingw32 --enable-mp3lame --extra-cflags=-I/local/include --extra-ldflags=-L/local/lib
- HINT: you can paste into MSYS by pressing your center mouse-button
- “–enabled-memalign-hack” is a Windows hack. Without this option ffmpeg always crashs with the message “removing common factors from framerate” when encoding AVIs.
- “–enable-mingw32″. I see no difference without it but we compile with MinGW and it would not do a harm when ffmpeg knows this
- “–enable-mp3lame”: Enable transcoding audio with the open-source mp3-lame-codec
- “–extra-cflags=-I/local/include –extra-ldflags=-L/local/lib”: The cflags- and ldflags-parameter sets the right path to your lame-installation which you did in step 3.d.
- Enter command: make (ffmpeg is being compiled; takes a few minutes)
- With “make install” you could now copy the ffmpeg.exe to c:Program Filesffmpeg. But there is no need to.
- Use FFMPEG
- Copy your compiled ffmpeg.exe from your MSYS directory to the directory where you like to transcode with ffmpeg
- Open the Dos-Shell and change to the directory where you copied the ffmpeg.exe
- Copy a test.mpg into your directory and enter the following command:
ffmpeg -i test.mpg -ab 56 -ar 22050 -b 500 -r 15 -s 320x240 test.flv
- Your first FLV should be encoded now
- Render Images from a Video
- Enter command:
ffmpeg -an -y -t 0:0:0.001 -i test.flv -f image2 test%d.jpg
- HINT: With -t you set the length of images to be extracted. Above we entered 1 millisecond the extract one image. If you miss this parameter all images of the video will be extracted
ZLib Support (e.g. for TSCC and Quicktime codecs). This should be compiled into FFMPEG. It is not an explicit compile in the configure statement. Do the following steps and after configure you should see that zlib is “on”.
Download and compile ZLib
Extract the files to your mysys directory
Change the directory in MSYS to that directory
Enter command ./confugure, make and make install.
AC3 Support
Add “–enable-a52 –enable-gpl” to your configure command
3GP Support
If you want to enable 3GP support you have to add the AMR audio codec. Download the TS26.104
REL-5 V5.1.0 26104-5??.zip here. Extract the codec into libavcodec/amr_float and add “–enable-amr_nb” to your configure command
XVID Support (thanks to garvin.thornten at datel.co.uk)
Download and install the codec from www.xlib.org (see xvidcore-xxxx/doc/install). Add “–enable-xvid –enable-gpl” to your configure command. When compiling with xvid codec in MinGW or cygwin you will get a “mkstemp” error when compiling “xvidff.c”. To fix this edit “libavcodec/xvidff.c” and add the following after the #includes. This will probably be fixed in a future ffmpeg release: ´
/* Added for windows compile ----------------- */ #include int xvid_ff_2pass(void *ref, int opt, void *p1, void *p2); void xvid_correct_framerate(AVCodecContext *avctx); int mkstemp(char* template) { char temppath[512]; if(GetTempPath(512,temppath)!=0) { if(GetTempFileName(temppath,"fil",0,template)!=0) { FILE *pFile; pFile=fopen(template,"w+"); if(pFile!=NULL) return (int)pFile; } } return -1; } /* ------------------------------------------- */
Link about qscale
removed “-f singlejpeg” as its identical to “-f mjpeg”
Audio doesn’t seem to work with ffmpeg. I tried it on a linux machine, but I did it with lame, so it shouldn’t be any problem.
Any ideas?
No idea. There should be no problems. Post your problem more detailed in the ffmpeg-mailinglist.
Cheers,
Sönke
About 10.XVID Support (thanks to garvin.thornten at datel.co.uk)
Which file should I add ur codes? xvidff.c?
Thanks!
And how about faac and faad2 enable for ffmpeg? Looking forward to it …
The file is xvidff.c as mentioned there.
faac and faad2 have to be enabled while configuring:
–enable-faac
–enable-faad
I am not sure if extra libraries have to be installed/compiled for this. maybe you can give it a try and report.
Cheers,
Sönke
zlib-support is also required for many Quicktime files b/c they can have their headers compressed with Zlib. I suggest to compile *always* with zlib support
Sönke,
Thanks so much for your information. I found this with Google. Between your wisdom and other snippets I’ve found on the web, I have a compiled FFmpeg that I’m very happy with.
I must say, your code addition to get –enable-xvid was a lifesaver. As far as I can tell, you are the only one on the web who has published this important info. May I ask how you learned how to do it? I’m starving for more info on FFmpeg. The code worked great once I included the full path to the windows.h include. For some reason msys couldn’t find it.
Also, you need the extra libraries if you –enable-faac and –enable-faad.
Hi,
thanks for the kind feedback but the xvid hack wasn’t me. Look at the thanks to in the xvid part. He emailed me the code to add it to my tutorial.
Also thanks to RockAttack. I changed the ZLib part.

FFmpegでswfへ変換
Import&Exportにswfが使えるんなんて、FFmpegって結構使えるのね。 こういうことは、学校で教えてください。つか、FLVエンコーダーもあるのかよ。 FFmepg(マルチメディア変換)の使い方 Sonke R…
works great - however is there a way to put the metadata into the flv at the same time as encoding? .. so it can be used with nice swf players?
FFMPEG does not support metadata. You can use FLVTool2 to inject metadata into FLVs. The Riva FLV Encoder uses both tools and supports FLV 1.1
Thanks for a nice website. I had problems while compiling ffmpeg, but thanks to your website, many things were cleared up.
Also, have you successfully compiled and run ffmpeg with the additional option -–enable-shared in the command line? The compiler complains that ld.exe cannot find -lmp3lame when -–enable-shared is added. If you have resolved this problem, please add the instruction to your ffmpeg guide as well.
Thanks.
Hi, I haven’t tried –enable-shared yet and don’t have a solution for your problem.
FFMPEG has the ability to grab video from a live source.
Has anyone successfully done this on a windows environment?
From what I know this works only on linux machines. This was discussed in the FFMPEG mailing list.
If that’s true, then I’m back to square one.
Know of any command line capture software?
I have tried a few but I don’t remember there names, sorry.
Anybody here that has build / compile instructions on howto build FAAD2 with MinGW32? I really want to build a ffmpeg version that supports as much codecs and fileformats possible, all using freely available opensource tools. To make things a bit more user-friendly I want to try and get it all working under Mingw32. Only FAAD2 is not working under Mingw32 right now. Any help / info is welcome.
Great stuff. I too would like to build a “mega ffmpeg” on linux to handle as many video input files as possible. A turorial on this..step by step…would be great in terms of the libs necessary and the order of installs, etc.
thanks!
Hi. I am trying to do the following: take an flv (audio only) file recorded with the Flash Communications Server MX and convert it to MP3 format on a
Windows XP Pro machine. I found your site and followed your excellent instructions at http://soenkerohde.com/tutorials/ffmpeg/
I was able to get everything to compile (although for others trying I should mention that there was one small problem not documented. When compiling LAME it
could not find some files in C:\msys\1.0\home\Admin1\lame-3.96.1\libmp3lame. The solution was to edit line 13 of one of the header files and then LAME
compiled fine). So after everything, I put some flv files record from the flashcom sample app into a directory called c:\video, navigated there in DOS and
tried to run:
ffmpeg -i a.flv m.mp3
and got the following error:

I tried a lot of other ffmpeg parameters but could not get anything to work. Do you have any ideas how to make this work? I know it can be done because I
have seen other sites doing this. Thanks very much for any help - you seem to be the resident guru on this topic!
Also, I should mention that I found some other suggestions such as using:
ffmpeg -i $input_dir$movie -hq -acodec mp3 -ar $22050 -ab 56 -f flv -s 320×240 -aspect 4:3 -y $output_dir$filename.flv
which supposedly is based off your own software! However when I try:
ffmpeg -i a.flv -hq -acodec mp3 -ar $22050 -ab 56 -f flv -s 320×240 -aspect 4:3 -y a.mp3
this I get:

Hi,
sorry no idea but I would try to ask the ffmpeg-mailinglist.
Your website is absolutely been a savior. It’s held the solutions to many of the problems that were encountered while compiling ffmpeg.
lame failed to compile with the following changes listed below.
the compiler does not have lame/mpglib in its list for include files. simple fix: edit libmp3lame/mpglib_interface.c line 13 to #include “../mpglib/interface.h”
May I suggest that you take this wonderful page and start a compressive wiki page to help people with their attempts to compile and use ffmpeg I’d be willing to help as well.
To get –enable-shared to work, I had to copy libxvidcore.a and libmp3lame.a to the MinGW\lib folder .. for some reason it wasn’t accepting the
–extra-ldflags=-L/local/lib
*shrugs* once I copied them the enable-shared option worked.

How can I conver a flv file to 3gp format file?
I found the way myself.
./configure –enable-memalign-hack –enable-amr_nb
http://www.xlib.org is down.
I wonder if xvidcore-1.1.0-beta2.zip from http://www.xvid.org/downloads.html can be used instead… I will give it a try
I have just compiled it with all the options you mention, using your excellent instructions.
A couple of hints:
I jumped into an error about lrintf, similar to this : http://permalink.gmane.org/gmane.comp.video.ffmpeg.devel/23188
I fixed it (I think) the same way: replace
static always_inline long int lrintf(float x)
with
static inline long int lrintf(float x)
in file libavutil/common.h.
(Maybe it wouldn´t have been necessary if I had done the next change before…)
Also, lame 3.96a was giving me trouble, I tried several older versions but finally achieved it with lame-3.97beta2, which I download form sourceforge. http://lame.sourceforge.net/ is outdated, use http://sourceforge.net/projects/lame and get it from to the Files section
Good luck!
I can’t add –enable-mp3lame to build the ffmpeg.Why?Should I download a lame and build?What I should do?
Yes, please check part 2. of my tutorial.
Thanks for your great site!
I need to build ffmpeg with AC3 encoding capabilities. I know i need to add ‘-enable-a52bin -extra-libs=”-la52″‘ to the line of configure. I’d installed A52DEC but I don’t know why, it’s not enough. Do you know what I must do now?
Cheers
You are welome but sorry, I dont know what you exactly have to do to include AC3
Great tutorial! very appriciated! Now one question
Lets say i put a swf containing a flv-player on site A 10mbit host and some flv files on a site B 100mbit host. i tell the flv-player at site A to play the flv’s at site B. Now some user goes watching the clip on my site, does he download the flv from site B or does the swf download the flv and broadcast it via site A?
Hi again. i have one more question. My movies encode succesfully with ffmpeg in linux but when i watch them with some flv player on my site, the “progressbar”-thing isnt “scrollable” until the whole movie is downloaded, i guess its because there’s no cue points added in the movie with ffmpeg. is this fixable with flvtool2? if so, whats the commando? i like your riva encoder though i must do this in linux since its takes forever to download the movie from my server and then reupload it. any help appriciated.
Hi ! thanx for the tut!
i did everything mentioned, but when i want to do the make command for the ffmpeg.exe, i get a bunch of parse errors like this:
avcodec.h:1987: warning: data definition has no type or storage class
avcodec.h:1988: parse error before “flv_decoder”
avcodec.h:1988: warning: type defaults to `int’ in declaration of `flv_decoder’
avcodec.h:1988: warning: data definition has no type or storage class
avcodec.h:1989: parse error before “rv10_decoder”
avcodec.h:1989: warning: type defaults to `int’ in declaration of `rv10_decoder’
avcodec.h:1989: warning: data definition has no type or storage class
avcodec.h:1990: parse error before “rv20_decoder”
Anyone an idea?
Hi,
@32: There is no broadcast but simply a download when you don’t use a special server like the Flash Media Server.
@33: it’s not because of the cuepoints but because of the missing metadata. you can inject the missing metadata with flvtool2: http://inlet-media.de
@34: sorry, no idea. I would ask the ffmpeg-mailinglist …
Ähmm it starts like this:
make[1]: Entering directory `/c/msys/1.0/home/ffmpeg/libavcodec’
gcc -O3 -g -Wall -Wno-switch -I/local/include -DHAVE_AV_CONFIG_H -I.. -I’/../c/ msys/1.0/home/ffmpeg’/libavutil -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GN U_SOURCE -c -o bitstream.o bitstream.c

avcodec.h:437: warning: data definition has no type or storage class
avcodec.h:672: parse error before “uint8_t”
do i have to put the specified files to the same folder ?
Do you try the latest version from CVS?
I would ask the FFMPEG list for such questions …
Cheers,

Hi,
Just wondering if you had any info on compiling ffmpeg for Windows Mobile. I’ve asked at the ffmpeg mailing list and at corecodec.com (tcpmp uses ffmpeg) but have not received any replies. I’ve tried a number of things (wince toolchains, configure options) but nothing has worked. Any help would be very much appreciated.
P.S. Great guide for compiling for Win32. It saved my butt.
Sorry, no idea. but good luck!
Hi, i’m just follow your instruction and
after compiling and installing of ffmpeg.
The error message popup was shown and it say that
“This application has failed to stard because libmp3lame-0.dll was not found.Re-installing the application may fix this problem”
Anyone an idea?
Thanks for the great tutorial. I followed the instructions for everything except xvid, and it all worked fine. Now I can create flv’s with video AND audio. NICE!
Do you, or anyone reading this, have any links to or examples of the command line to make ffmpeg generate a 3gp with both video and audio?
I have 15 second video clip that I’ve broken into a series of jpegs and a single .wav file. I can now, thanks to this site, encode that as a flv with both the video and audio, but I’m not able to figure out the right set of command line parameters to encode it as a 3gp. I have an earlier version of ffmpeg (precompiled from the Gallery2 source forge project) that I am able to generate an mp4 with, and by simply changing the extension to .3gp the file plays on my Samsung cellphone, but it does not have audio.
Any advice, links or examples anyone?
Hey gugcula:
I had the same problem. Simply look in your msys’s local\bin and the libmp3lame-0.dll file is there. Copy that into the same directory as your ffmpeg.exe and you are good to go.
On my setup, that directory is C:\msys\1.0\local\bin
After compiling and copying lib are completed, i’m trying
to convert but it always display these message
C:\Program Files\FFmpeg>ffmpeg.exe -y -i legendheroes_ot_psp_101805.mpg sample.flv

Could you guys offer any solutions?
hi gugcula,
sorry no idea. I would ask in the ffmpeg-mailinglist.
ok i’ll go there thank you for provide this good tutorial
Hi,
i want to do video processing using opencv and VC++
i don’t now how to install ffmpeg for windows and how to use ffmpeg with opencv and vc++ to do video processing could please anyone give me the stepwise procedure to do this.
I want to use ffmpeg to convert from 3GP to FLV. Unfortunatly the video-stream is not converted correctly. The video of the resulting FLV runs almost twice as fast, as in the origianl 3GP. I a,lso notice this in ffmpeg’s output:
…Input
Stream #0.0: Video: h263, 176×144, 11.51 fps
…Output
Stream #0.0: Video: flv, 176×144, 20.00 fps, q=2-31, 200 kb/s
I use the following command:
ffmpeg -i 77493_1139671907306.3pg -y -ar 22050 test.flv
Does anyone have an idea about this? The option -r does not fix my problem.
I use ffmpeg version 0.4.9-pre1, build 4718
Thnaks alot and kind regards, hans
Ah, sorry. I need to add, that this tutorial helped me alot getting ffmpeg started
Hi Hans,
i don’t know where the problem is. I would ask the ffmpeg-mailinglist.
Hi Sönke,
thanks for your quick answer. I should have checked out the latest version from the CVS-Repository in first place. After a little bit of struggeling with the make-process I compiled it and everything is running fine now.
Kind regards, Hans
Hi Sonke,
Just wanted to thanks for the great info.
Thank you so much for great tutorial here. I have been trying to compile ffmpeg with AAC on windows. I followed everything as you explained but somehow ffmpeg failed to find the ffmpeg libraries. I am able to compile AAC and xvid sepertly and set the path. I used follwing configure command

I could solve the problem by copying libfacc.dll into Mingw32 include directory i.e. MinGW/lib/gcc/mingw32/3.4.2 and use the following config to build ffmpeg with xvid and aac
./configure –enable-shared –disable-static –enable-memalign-hack –enable-
xvid –enable-gpl –extra-cflags=-I/C/mplayer/msys/xvidcore/src –extra-ldflags

mplayer/msys/faac/include –extra-ldflags=-L/c/mplayer/msys/faac/libfaac/Debug
now i get following errors

hi, really good stuff both this and the riva gui!
i do have problems with my ffmpeg install, as the sound comes out all distorted and uhm buzzy. ive installed amr_nb and lame. riva converts the file just fine though. ever noticed anything like this?
thanks for your information on –enable-xvid.
It is really helpful. there is nobody provided such information on internet exept here.
I share some my experience on –enable-xvid here:
First, I changed in ffmpeg configure:
1, point to right xvidcore library directory:
–enable-xvid) xvid=”yes”
extralibs=”$extralibs -L/usr/local/lib -lxvidcore”
2. if test “$?” != “0″ ; then
rm config.h
mv -f $TMPH config.h
else
echo “config.h is unchanged”
fi
because it can not mv to config.h.
3. here is my configure command line:
./configure –disable-static –enable-shared –enable-memalign-hack –enable-
xvid –enable-gpl –enable-mingw32 –extra-cflags=-I/local/include –extra-ldfl
ags=-L/local/lib
4.
make change in xvidff.c and xvid_rc.c
pointing xvid.h to right position.
On my pc this is the case, different from PC to PC:
#include “../../../../local/include/xvid.h”
5.
add the scripts mentioned above in xvidff.c
6,make
just found out why i got distorted buzz instead of the correct audio. turns out i needed to compile with amr_nb-fixed as well.
There’s a space between “windows” and “.h” in your code.
Just found that out cuz cp & paste didn’t work
#include
Thanks for the hint but this is a problem of the blogsoftware I am using. I have to upgrade to a newer version but had no time yet.
Does ffmpeg can convert the file with extends “.wmv”, what is the command line.
yes, but only wmv7/8.

Derek, do you receieve any linking errors when you compile with the lame lib files? - my only concern is, is that its not actually linking into the ffmpeg executable, - have you tried to convert from wave to mp3 using just the lame binary? and if so does it work
I have no idea about these,
I just follow the ZLib support then make again.

How can I use FFMPEG libs to create jpg files from a video file?
I have write some code to get a frame from video, but I do not know how to convert this frame to a jpeg file. I have tryed to convert FFMPEG AVFrame to a GD gdImage, and then save this GD gdImage to a jpeg file(ffmpeg-php use this kind of method), but the jpeg file I generated is incorrect.
Can you help me? thanks a lot.
you can extract the first image with
ffmpeg -an -y -t 0:0:0.001 -i test.flv -f image2 test%d.jpg
without -t 0:0:0.001 all frames are extraced.
i have installed ffmpeg into my linux system.
and i am able to covert the videos,
but there is no audio in my output flv, what i am missing?
what’s wrong ?

thank you!
ffmpeg -i test.mpg -ab 56 -ar 22050 -b 500 -r 15 -s 320×240 test.flv

Anyone has an idea?
My files are being converted …. but they output with a 0kb file size… none of the videos work.. but they do output to that 0kb file size.. What could be the problem?
Also I’m not really familiar with MSYS and MinGW. Using them can I compile ffmpeg so that I can used it on Debian?
Thanks for your help!

This seems to be the best place for information on ffmpeg. Thanks Sonke!
I’m using Debian and I’m installing all my packages using apt-get. But I can’t figure out where the ffmpeg directory has been created. So I’m having a hard time trying to figure out how to configure ffmpeg to work with lame. Does anybody have any idea how to do this.
Thanks in advance for any help that anybody can provide!

Anyone has an idea?
I am not sure but try “-f mjpeg”

Is there any way you guys could put together an “idiots guide to installing ffmpeg on windows”??
This tutorial is all giberish to me
Sorry but this is free information which I produced in my freetime.

Hello! Thanks for this post I think it is very useful!

Thanks for your help.
Sorry for previous question. I solved the problem. I had not mp3 lame enabled.
How come when i try to execute ./configure the console says “./configure exec: bash: not found”
Check the tutorial I linked at the beginning of my tutorial (Update …)
About Riva FLV Encoder 2.0, I’ve found a bug about ffmpeg not detecting ac3 audio format when trying to convert an mpeg to FLV vidéo.
I’ve tried with an other ffmpeg.exe but it doesn’t accept the -hq ans the quality is really poor !!!
Any idear ?
Thanks in advance
-hq is not supported in the latest ffmpeg-builds.
I am afraid this could only work if the Riva FLV Encoder get an update because -hq is set by default.
Thanks a lot Sönke for your quick answer !
Yes , I’ve seen that Riva FLV Encoder put the -hq in the command line.
For testing, I’ve remove the -hq in the file “encode.bat” generate, and then it works but the quality is really poor !!
So I’m asking me how to keep a good quality without the -hq option …
Thanks again.
Hi YannX,
sorry, but I have no idea and I would recommend your ask in the ffmpeg mailing list.
Hi,
Please help me. When i convert my movie file(wmv,mpg etc) to flv, it doesnt have a sound/audio. I already install LAME, mencoder. I follow this line:
ffmpeg -i test.mpg -ab 56 -ar 22050 -b 500 -r 15 -s 320×240 test.flv
Thanks,
mike
Please ask in the ffmpeg mailinglist.
Hi,
ok thanks, But just for an info. I think avi, wmv wont be properly converted since it is made from windows. I try to install a ffmpeg to windows and generated .flv works fine. I already triend install a LAME and MPlayer to my CENTOS box but still no sounds. Thanks anyways.

Hey Guys,

No compatible shell script interpreter found
The configure script requires a POSIX compatible shell such as bash or ksh
This bash version (2.04.0.(1)-release)is broken on your platform.
Upgrade to a later version if available.
Im not evern sure where to start with this…anyone help :???
Well…firstly thansk for a great tute…I got this working, at least locally.
Im trying to run this from a web server now, sending the command line option using PHP.
For some reason, its seems to work (the videos encoded!) But my browser out puts:

The specified CGI application misbehaved by not returning a complete set of HTTP headers.
I cant work this out at alll…any help?
Hi,
I did not try it but this looks promising: http://lists.mplayerhq.hu/pipermail/ffmpeg-user/2006-October/004773.html
Hi,
thanks for this great tutorial…
Well, i needed some days to compile ffmpeg and all the needed libraries on my Windows-Machine (cause im not familar with MSYS & MINGW).
But now i’ve made my first stable build today (from SVN revision 7218) including avisynth-support and lame-mp3 encoding.
Feel free to download my build here: http://vergin.org/files/FFInstall.exe

I know that u’ve mentioned it a cpl of times earlier as a response that this isn’t a support forum but pls can u just write in the command to generate an flv output from two or more video[mpg ..] files using ffmpeg.
I want to concatenate two video files and write an flv output.
Any help would be greatly appreciated.
Thanks in Advance.
Kreez.
I do not know the exact command and recommend searching the ffmpeg maillinglist archive. I remember that this usecase was mentioned a few times.

Hello,
This was really helpful to me but i have doubt in it after creating a flv file from mpeg, when extracting a screen shot it extracts a .jpg file of the same dimensions as the flv file is their any method or any parameter to use to specify my own parameters in the command
ffmpeg -an -y -t 0:0:0.001 -i test.flv -f image2 test%d.jpg .
ie. i want a screen shot of 50×50 dimension
thank you for ur help in advance
Execute ffmpeg.exe in the command line and you see all options. There is the option -s for size and also an option -img to specify an image format.
When I compile ffmpeg in mingw32,How to configure ffmpeg to support with vhook?
Thanks a lot for your help
George, I would recommend you ask the ffmpeg mailinglist
Hey thanks for the tuto.
I haven’t finished yet. I reach to compile lame!
But as i didn’t find solution on internet for my compilation problem and get it done, yeah i feel really good, here is some help:
I had this error for make:
../libtool: cygpath: command not found
so i re-install msys and minGW out of Program Files directory. The space was to much possibility of path difficulty. to be sure i re-install cygwin too. All this in c:/dev/.
From that i followed your instruction and it works!
thank you all.

First of all I would like to thank you for this great tutorial. The original ffmpeg does not seem to output any good information while converting video files. Its hard to track for errors and I would like the change how this works since I’ll be calling ffmpeg from my application and I need to know if the video is converted successfully or not. What is your suggestion? Where should I start?

Hi,
I’d install ffmpeg with faac, faad, lame, etc support. avi, mpg, wmv converting to flv without problems. but I cant convert mov to flv.

Hi,
I need lame.exe file.I searched it. I got lame-3.97 & lame-3.92. but these two things doesnt contain lame.exe
file.Because I want compile that file.Because already i did installation of MinGw & Msys.I want to compile lame.exe.Please give me right passage to this one.
Hi,

Hi,
I am not familar with ffmpeg concepts. How to extract lame to my Msys home directory.Please give me right solution to me and where do i write the following things
like “Enter the following commands:

1. ./configure //(takes a few minutes)
2. make //(lame is being comiled; takes a few minutes, too)
3. make install”
Please give me right solution…
Lame itself has nothing to do with ffmpeg. it can be compiled into ffmeg. just download the lame sourcecode and extract it to the directoy where you installed msys and there into the subdirectory where you home dir is located. Then follow my tutorial.

I got the err when I was configured Lame in msys.

Prabhu, you need to use a newer version of bash shell, i.e. bash3.1. It can be downloaded from http://prdownloads.sourceforge.net/mingw/bash-3.1-MSYS-1.0.11-snapshot.tar.bz2?download
BTW, I would recommend a very detailed tutorial at http://arrozcru.no-ip.org/ffmpeg_wiki/tiki-index.php?page=HomePage

[...] FFMPEG kurulumu? - Zoque.Forum ayn
Thank you for your help! I managed to get it going thanks to this guide
I did however get the same problem as listed about “Broken shell detected. Trying alternatives…” so I compiled an older version and that worked fine!
For Prabhu:
Download updated bash for MSYS from:
http://sourceforge.net/project/showfiles.php?group_id=2435
right now, last version is bash-3.1-MSYS-1.0.11-1.tar.bz2
Copy bash-3.1-MSYS-1.0.11-1.tar.bz2 to c:\msys\1.0 and extract it (bash.exe should go into C:\MSYS\1.0\bin).
You need to do this because ffmpeg’s configure script doesn’t work with bash 2.0.4 that comes with MSYS.

Hi Sonke,
This was the best guide i have seen in using ffmpeg. Brilliant work. The exe is working fine for me. But now I am facing an issue as I wanted to do the ffmpeg conversion inside the webserver and it is not advisable to call the exe from a server script. Hence was wondering, whether there is any way of creating a java class or api for ffmpeg. Have you ever thought about such a possibility. If so, could you please advise me on that.
Thanks in advance,
Arun George
Hi Arun, sorry but I have no thoughts on that. There was a project called ffmpeg-php which had ffmpeg as a php module. you might want to check how they solved it.
hey guys. ı try to install ffmpeg and ı dont know where will a write
//./configure //(takes a few minutes)
//make //(lame is being comiled; takes a few minutes, //too)
//make install
please help
This has to be entered in the MinGW console
ı wrote it but doesnt anything.
see you it
“$ ./ configure
sh: ./: is a directory”
did you see?
you said you need to wait for a few minutes but nothing
you have got a space between ./” “configure
has to be ./configure
and you see a lot of output after this command so you have to wait until the output says “finished” or something like that …
akn@EFLATUN–AKıN ~
$ ./configure
sh: ./configure: No such file or directory
akn@EFLATUN–AKıN ~
$ ./ configure
sh: ./: is a directory
my friend ı tried it so many times and ıt never says “finished”.
do you know anythinga bout it Sönke
thanks
Then you are simply in the wrong directory.
Which configure do you want to execute and where is it located on your filesystem and did you change to this directory within MinGW?
no ı did not change any directory in minGW .
do ı need to change it.
(if ı can solve that problem ı will so pleasure to you)
thanks.
and ı cant use a real server my server works in my pc for this present. also ı dont use riva flv encoder, does it induce those mistakes?
of course you have to change to the directory in your case to the dir where you extracted lame.
can you explain me more specific . what will ı change in minGW?
thanks
sorry, no time.
thanks for everthing sönke

Hi there!
Thanks for such a great help! I really really appriciate this. I can convert my videos and grab the thumbnails. But the only I am having is the audio encoding which fails due to “output buffer too small”.
I have tried the 3.97 veriosn of lame to o but was not helpful. Please help me with this too.
There is another question too. I have the binaries from Ramiro Polla for ffmpeg which I am using. When I applied the code it was not working obviously cuz there were no configure and other c files only binaries. So I got a zip of version ffmpeg-0.4.7. I pasted em in the same folder as the binaries. Compiling ffmpeg generates non executables so do i have to use the binaries which I am already using? How does this connects?
Please I really need your help!
