API changes, most recent first:
2014-04-xx - xxxxxxx - lavc 55.54.0 - avcodec.h
Add AVCodecContext.side_data_only_packets to allow encoders to output packets
with only side data. This option may become mandatory in the future, so all
users are recommended to update their code and enable this option.
2014-xx-xx - xxxxxxx - lavu 53.16.0 - frame.h, pixfmt.h
Move all color-related enums (AVColorPrimaries, AVColorSpace, AVColorRange,
AVColorTransferCharacteristic, and AVChromaLocation) inside lavu.
