Known problem: incorrect video aspect ratio in MSE mode

[AlexxIT]

This happens if the RTSP camera does not send video codec information or sends it incorrectly. The SPS and PPS parameters in the response to the RTSP DESCRIBE.

This can be fixed using ffmpeg source. But this will add a delay to the start of the stream.

streams:
  camera1: ffmpeg:rtsp://...

Without ffmpeg source, this requires significant tweaking of go2rtc. Specifically, analyzing the stream before starting the streaming.

When using the Advanced Camera Card, I was able to work around this issue with:

type: custom:advanced-camera-card
cameras:
  - camera_entity: camera.video_porteiro
    live_provider: go2rtc
+   dimensions:
+     aspect_ratio: "16:9"
+     layout:
+       fit: fill

I have the same issue accessing tapo cameras in Frigate using the tapo:// feed instead of rtsp, the stream renders in 4:3 instead of 16:9 in the Frigate live feed. I'm not sure how to adjust the tapo:// url to include the ffmpeg workaround, is this possible for this sort of stream connection? TIA.

You can do:

streams:
  cam_tapo: tapo://<your-tapo-url>
  cam: ffmpeg:cam_tapo#video=copy#audio=copy

You can do:

streams:
cam_tapo: tapo://
cam: ffmpeg:cam_tapo#video=copy#audio=copy

thanks very much!

It's clear how to fix this without ffmpeg. But this is a significant modification to go2rtc. And it won't be available anytime soon.
