Buster 202007012 - Unable to assign Audio PID

Hello Dave,

With the DVB FW, I am now able to run Buster with the C920 and audio at SR 4000 without problem. So I decided to test it on the HB9TV Network which uses DVB-S, SR4000, Video PID 33 and Audio PID 49, I configured the PIDs on Menu 29, but unfortunately the Audio PID is set to 34 when transmitting...

Correct behavior for this configuration or bug ?

Merci for your help

Hi Michel

It is a design feature of Evariste's H264 encoding software that the Audio PID is always the video PID + 1. The reason that you can set it in Portsdown is that my MPEG-2 encoding software allows the audio PID to be set as you want.

I think that you could change Evariste's code to set it as you want (and then recompile). The relevant file is avc2ts.cpp and you would need to change this line I think:
https://github.com/BritishAmateurTelevi ... .cpp#L2338

Please let me know if it works!

Dave
