Introduction to FFmpeg
FFmpeg is a solution to record, convert and stream audio and video. It is a very fast video and audio converter and it can also acquire from a live audio/video source. Designed to be intuitive, the command-line interface (ffmpeg) tries to figure out all the parameters, when possible. FFmpeg can also convert from any sample rate to any other, and resize video on the fly with a high quality polyphase filter. FFmpeg can use a video4linux compatible video source and any Open Sound System audio source.

Using a SVN Snapshot
Make sure that you have Subversion installed before issuing the following commands:
svn co svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
tar cvjf ffmpeg-r$(svnversion ffmpeg).tar.bz2 ffmpeg
Dependencies
Optional
Configuring
Look at the output of ./configure --help and add the parameters for the optional dependencies you have installed.
A few options you may want to use:
--enable-pp --enable-liba52 --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libogg --enable-libtheora --enable-libx264 --enable-libxvid --enable-libvorbis
Non-Multilib
If you are not building a SVN Snapshot apply the following patches:
patch -Np1 -i ../ffmpeg-0.4.9-pre1-gcc4-1.patch && patch -Np1 -i ../ffmpeg-0.4.9-pre1-amr_fixes-1.patch
Compile the package:
./configure --prefix=/usr --enable-shared \ --enable-pthreads --enable-gpl \ --disable-ffplay --enable-postproc && make
Install the package
make install
Multilib
32Bit
If you are not building a SVN Snapshot apply the following patches:
patch -Np1 -i ../ffmpeg-0.4.9-pre1-gcc4-1.patch && patch -Np1 -i ../ffmpeg-0.4.9-pre1-amr_fixes-1.patch
Compile the package:
export USE_ARCH=32 && CFLAGS="${BUILD32} -fno-PIC" \ ./configure --prefix=/usr --cc="gcc ${BUILD32}" \ --enable-shared --enable-pthreads \ --enable-gpl --disable-ffplay --enable-postproc && make
Install the package
make install && mv -v /usr/bin/ffmpeg{,-32} && unset USE_ARCH
N32
If you are not building a SVN Snapshot apply the following patches and sed:
patch -Np1 -i ../ffmpeg-0.4.9-pre1-gcc4-1.patch && patch -Np1 -i ../ffmpeg-0.4.9-pre1-amr_fixes-1.patch && sed -i 's:$(prefix)/lib:&32:g' $(grep -lr '$(prefix)/lib' *)
Compile the package:
export USE_ARCH=n32 && CFLAGS="${BUILDN32} -fPIC" \ ./configure --prefix=/usr --cc="gcc ${BUILD32}" \ --{,sh}libdir=/usr/lib32 \ --enable-shared --enable-pthreads \ --enable-gpl --disable-ffplay --enable-postproc && make
Install the package
make install && mv -v /usr/bin/ffmpeg{,-n32} && unset USE_ARCH
64Bit
If you are not building a SVN Snapshot apply the following patches and sed:
patch -Np1 -i ../ffmpeg-0.4.9-pre1-gcc4-1.patch && patch -Np1 -i ../ffmpeg-0.4.9-pre1-amr_fixes-1.patch && sed -i 's:$(prefix)/lib:&64:g' $(grep -lr '$(prefix)/lib' *)
Compile the package:
export USE_ARCH=64 && CFLAGS="${BUILD64} -fPIC" \ ./configure --prefix=/usr --cc="gcc ${BUILD64}" \ --{,sh}libdir=/usr/lib64 \ --enable-shared --enable-pthreads \ --enable-gpl --disable-ffplay --enable-postproc && make
Install the package
make install && mv -v /usr/bin/ffmpeg{,-64} && ln -sfv multiarch_wrapper /usr/bin/ffmpeg && unset USE_ARCH
