API changes, most recent first:
2017-xx-xx - xxxxxxxxxx
Change av_sha_update() and av_md5_sum()/av_md5_update() length
parameter type to size_t at next major bump.
2017-05-05 - xxxxxxxxxx - lavc 57.94.100 - avcodec.h
The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
