API changes, most recent first:
2013-10-xx - xxxxxxx - lavc 55.27.0 - avcodec.h
Deprecate AVCodecContext.error_rate, it is replaced by the 'error_rate'
private option of the mpegvideo encoder family.
2013-11-xx - xxxxxxx - lavc 55.26.0 - vdpau.h
Add av_vdpau_get_profile().
Add av_vdpau_alloc_context(). This function must from now on be
