Transcoding OPUS to AAC yields a muted audio track

[felipecrs]

I flashed Thingino in one of my cameras, and this firmware is capable of sending audio in OPUS format, which is great.

My go2rtc config is like the following:

streams:
  my_cam:
    - rtsp://thingino:[email protected]/ch1
    - ffmpeg:my_cam#audio=aac

When I play in VLC with:

rtsp://go2rtc:8554/my_cam?video&audio=opus

Everything works ok. I can hear audio just fine.

But when I play with:

rtsp://go2rtc:8554/my_cam?video&audio=aac

There is no audio. In fact, the AAC track is included, but it's muted.

I wonder, have you ever tried transcoding OPUS to AAC? Maybe I'm not alone.

PS: I don't see any error in my logs.

I didn't have a source that supports OPUS out of the box. Unify cameras support it via RTSP protocol.

I can give you access to my camera stream if you want.
