flv demuxer/muxer can decode/encode metadata in data stream. Does mpegts demuxer/muxer have the same function?
Mpeg2 ts standard provides several methods to transport metadata. Is there some apporpriate way to transport some metadata at some fixed interval?

I have read the source code of mpegts demuxer/muxer in ffmpeg, which doesn't support decoding/encoding self-defined metadata.
