does mpegts muxer/demuxer support metadata

qw
Hi,


I try to insert my defined metadata into ts file using the following command:


ffmpeg -i input.ts -c copy -copyts -metadata message1="test" -f mpegts output1.ts


If I use the following command to copy metadata from ts file to flv file, my defined metadata doesn't exist:


ffmpeg -i output1.ts -c copy -copyts -map_metadata 0 -bsf:a aac_adtstoasc -f flv output2.flv


flvmeta --dump --yaml output2.flv


Mpeg 2 transport stream supports several ways to send and receive metadata. Does mpegts demuxer/muxer support metadata? which tools does mepgts demuxer/muxer support to transport metadata?




Thanks!


Regards


Andrew

Can you provide a sample that shows one of these ways?

any ts file can reproduce the same result.
