Are you sure you're compiling/linking against your compiled
FFmpeg version?
What's the result of:
avcodec_find_encoder(CODEC_ID_H264); ?
If that's the problem then you should double check your
compilation/linking commands, and make them points to the right path
where you installed your version of FFmpeg.
