MISB ST1402 (available at https://gwg.nga.mil/misb/docs/standards/ST1402.2.pdf) has two kinds of KLV metadata - synchronous and asynchronous. These patches provide initial support for that. Synchronous is stream_type = 0x15 for "Metadata carried in PES packets" with stream_id = 0xFC for "metadata stream."
Asynchronous is stream_type = 0x06 for "PES packets containing private data" with stream_id = 0xBD for "private_stream_1." We do have some support already (on writing), see https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/mpegtsenc.c#L1396 for the stream_id handling. We need to be able to set the stream_type as well though. Brad Brad Hards (2): Add constants for KLV pseudo-profile. Set stream_id correctly based on KLV profile selected. libavcodec/avcodec.h | 3 +++ libavformat/mpegtsenc.c | 6 ++++++ 2 files changed, 9 insertions(+) -- 2.17.1 _______________________________________________ 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".
