Jetson Nano Save two usb webcam streams picture in picture pipeline wont start

Hi,
A few suggestions:

  1. You may run audio-only pipeline to confirm audio source is good.
  2. Set sync=false in filesink. This can disable A/V sync mechanism of gstreamer
  3. Run sudo jetson_clocks.

One case we have tried is onboard camera + USB audio input. FYR.
