#8660 (mpegts recognize s302m as private data stream) – FFmpeg
https://trac.ffmpeg.org/ticket/8660
Description. When using s302m audio codec in mpegts, the current ffmpeg version gives then warning: [mpegts @ 0x55fa474108c0] Stream 1, codec s302m, is muxed as a private data stream and may not be recognized upon reading. That is a wrong message, because s302m should be listed as a audio codec. I read that the list of supported codecs are incomplete.

Looks like MPEG-TS supports AES3-formatted PCM audio as private data, as specified by SMPTE 302M. There is currently a s302m encoder/decoder in ffmpeg that will allow you to easily accomplish your goal.

[RFC] SMPTE 302M AES 3 stream in mpeg ts - ffmpeg-devel ...

1) define PARSER_FLAG_S302M and then select s302_parser in av_parser_init. It may not be appropriate though. 2) need_parsing == 3 Problem here is that av_parser_init only takes codec_id as argument. About packets disappearing problem, it seems pes->state is not reset after av_find_stream_infos, and S302M stream does not start with TS
