Compile And Install FFMPEG on Redhat RHEL4

I just had the wonderful opportunity to set up a video sharing site on Redhat Enterprise Linux 4. Yeah. Four.

The worst part was getting ffmpeg to work, so here are my notes.

(download, extract, etc.)

Configure, Compile, and Install FFMPEG
./configure --enable-libmp3lame --enable-libvorbis \
--enable-libxvid --enable-shared --enable-libfaac \
--enable-libfaad --enable-gpl --enable-libtheora \
make install

Create Symlinks

ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51
ln -s /usr/local/lib/libavformat.so.52 /usr/lib/libavformat.so.52
ln -s /usr/local/lib/libavdevice.so.52 /usr/lib/libavdevice.so.52
ln -s /usr/local/lib/libx264.so.58 /usr/lib/libx264.so.58
ln -s /usr/local/lib/libtheora.so.0 /usr/lib/libtheora.so.0
ln -s /usr/local/lib/libfaad.so.0 /usr/lib/libfaad.so.0
ln -s /usr/local/lib/libfaac.so.0 /usr/lib/libfaac.so.0

If you don't create these symlinks you will get errors like:
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file

Run ffmpeg and it should spit out that insane list of options, wihout any errors.

Online Flashcards and Quizzer

I just launched a new online flash cards and quizzing site called FB_Quizzr. The site is primarily intended to be used as a Facebook application.
