* commit '728d90a0c1973661a9e73da697bf4f90c9d19577': h264: decouple h264_sei from the h264 decoder Main changes: - SEI decoding doesn't have access to the debug flag in the codec context so a few logging are dropped. - naming of quincunx_sampling_flag and frame_packing_arrangement_type are kept as they are in FFmpeg instead of respectively quincunx_subsampling and arrangement_type used in Libav because the former match the specifications. - don't reset the x264 build info once read in order to fix fate-h264-lossless (change by Hendrik) - H264Context.has_recovery_point and deprecated AVCodecContext.dtg_active_format are set after ff_h264_sei_decode() based on the SEI state since ff_h264_sei_decode() doesn't have access to H264Context anymore. - frame_packing_arrangement_type is not checked against <= 0 in decode_postinit() since it is always read as a positive value with get_bits(). This fixes a -Wtype-limits warning by GCC spotted by Michael. Side Notes: - tested that ffprobe on the file from ticket #3652 still returns 4 keyframes - tested that playback from ticket #3063 still works Merged-by: Clément Bœsch <clement@stupeflix.com> Signed-off-by: Hendrik Leppkes <h.leppkes@gmail.com>
