It contains quite a lot of things that are missing here, like lots of constifications (i.e. AVFormatContext.(audio|video|subtitle)_codec; avcodec_find_(de|en)coder and the corresponding *_by_name functions return const AVCodec*; av_find_best_stream() has been made const-correct; avdevice_list_(input_sources|output_sinks); the avdevice_next API (the last next API in existence -- does someone know why?).
Your list contains errors, besides the first entry being duplicated: > * AV_CODEC_CAP_INTRA_ONLY and AV_CODEC_CAP_INTRA_ONLY removed, use > corresponding > AVCodecDescriptor.props values instead ... > * avcodec_find_best_pix_fmt_of_2 replaced by avcodec_find_best_pix_fmt_of_2 - Andreas _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
