API changes, most recent first:
2014-xx-xx - xxxxxxx - lavf 55.20.0 - avformat.h
The proper way for providing a hint about the desired timebase to the muxers
is now setting AVStream.time_base, instead of AVStream.codec.time_base as was
done previously. The old method is now deprecated.
2014-06-10 - xxxxxxx - lavf 55.43.100 - avformat.h
New field int64_t max_analyze_duration2 instead of deprecated
int max_analyze_duration.
