[FFmpeg-user] mpegts multiple streams metadata set problem.

[Alexei]

Hey folks!
I'm trying to set metadata on some input streams before muxing them into one. But non of the options work.

inputflags="-fflags +igndts -reuse 1 -analyzeduration 3M -thread_queue_size 1M -probesize 3M -rtbufsize 356M"
udpflags="pkt_size=1316&fifo_size=2379746&overrun_nonfatal=1&buffer_size=655350000"
streamsrc='udp://239.5.6.1'

while [[ ! -e /tmp/stream.stop ]]; do
ffmpeg \
$inputflags -i "$streamsrc:5201?$udpflags" \
$inputflags -i "$streamsrc:5202?$udpflags" \
$inputflags -i "$streamsrc:5203?$udpflags" \

I did try -metadata:s:v:N, where N is stream number, -map-metadata 0 - nothing works. Output shows:

Output #0, mpegts, to 'udp://239.5.5.3:5800?pkt_size=1316&fifo_size=57113926&bitrate=43900000&overrun_nonfatal=1&buffer_size=65535000':

Somehow it sets metadata for audio stream. But at the same time

ffprobe -i udp://239.5.5.3:5800
...

I have this output from ffprobe.


also, I've tried metadata option before -f mpegts, after and in other different places. Switched to rpt_mpegts. It sets metadata, but messes up services. I have IP Probe
DVB-T decoder that can't decode it, it sees one channel that has 24 streams and not 24 channels.
