问题
I am trying to build ffmpeg for windows (Xp - SP2) as given here.
./configure -–extra-cflags=”-mno-cygwin -mms-bitfields” -–extra-ldflags=”-Wl, -add-stdcall-alias” -–enable-memalign-hack -–enable-shared -–disable-static -–target-os=mingw32
The above command is placed in a myconfig
file as instructed and when i run ./myconfig
, the following error is displayed:
Broken Shell detected. Trying alternatives.
Trying Shell bash
Unknown option "-–extra-cflags=-mno-cygwin".
As suggested in the link i tried various options but still i was not able to succeed.
My environment is Win XP with:
- MinGW-5.1.6,
- bash-2.05b-MSYS,
- MSYS-1.0.10,
- ffmpeg-0.5
EDIT:
After certain changes in the above command by referring howto i was able to successfully run the make command and i found the following DLL's in their respective directory
- ffmpeg\libavcodec\avcodec-51.dll
- ffmpeg\libavformat\avformat-51.dll
- ffmpeg\libavutil\avutil-49.dll
But i didn't see any ffmpeg\ffmpeg.exe file :(
What could have gone wrong?
回答1:
Ramiro's FFmpeg for Windows site gives much better step by step instructions, and has a community forum that you can ask questions on if the Wiki doesn't answer your question already.
回答2:
Possibly off topic, but I wrote a script for Cygwin to do this.

Finally I succeeded to build ffmpeg on windows with this blog http://www.finalmediaplayer.com/source.html
You may also want to add lame and x264 to your build.
- Extract the tar to /ffmpeg/libraries
./configure --prefix=/ffmpeg/olibs --enable-static --disable-shared
make
make install
Additionals libraries:
- FAAC http://downloads.sourceforge.net/faac/faac-1.28.tar.gz
- FDK-AAC http://sourceforge.net/projects/opencore-amr/files/fdk-aac/fdk-aac-0.1.1.tar.gz/download
Reconfigure your ffmpeg again with the options: --enable-libx264 --enable-libmp3lame --enable-libfaac --enable-libfdk-aac
