Is there any way to get DVB complaint CBR MPEGTS from Decklink SDI INPUT?

Currently using below command but not getting CBR.

ffmpeg -re -f decklink -i 48:00000000:00300a00 -vcodec libx264 -s 720x576 -r 25 -flags cgop+ilme -x264-params interlaced=1 -sc_threshold 1000000000 -b:v 4M -minrate:v 4M -maxrate:v 4M -bufsize:v 4M -acodec mp2 -ac 2 -b:a 192k -f mpegts udp://

Hello, Fahad.

Unfortunately, we have no experience with Decklink cards and do not provide any best practices for generating DVB compliant signals with FFmpeg.

Please contact Decklink support for clarification.

Thank you.
