Hi,

Hope you are doing well.

I am struggling with Proper CBR MPEGTS UDP stream from Decklink SDI input.

On Stream analyzer I am getting error of PCR accuracy.

Regards,

Fahad

you can try -muxrate parameter of mpegts muxer and bitrate parameter of output udp url.

but i am not sure it helps to fix PCR accuracy.

try piping tsduck with ffmpeg
