Audio in mpeg-ts files

[mhaines4102]

Question

`I have an media MTX implementation against an rtsp source. As long as the recorded file format is MP4 I get audio. But when I change to MPEG TS the audio stopped. I did an FF probe file and did not see encoded audio. Is there something that needs to be set in the configuration for the audio to be in the MPEG TS files?

I am using the docker image. `
