Describe the problem you are having

I am seeing a similar issue to #14309 with an h265 cam and go2rtc where certain videos will never play. When I first launch frigate, everything works well. At some point, my ability to play back recordings fails. When opening a single .mp4 file from the affected period I get a file ~10MB in size but thinks it has a ~4h duration, seen below. My config is very simple with one camera right now as I've been testing, also below. If I restart Frigate, thinks seem to work well for a little bit then choke again.

note: even though the stream is named h264Preview_01_main, the resulting data is hevc.

On some cameras, the discrepancy between media length and size is often due to the use of a "smart codec" that severely alters the keyframe interval on the footage.

I've seen this with Hikvision's "+" codecs, but I don't own a Reolink to be able to confirm. Can you check your camera's settings to see if there's any kind of "smart codec" enabled?

I've made the change and will let it run for the day and see.

mbaran5 Oct 16, 2024

this seems to have helped, as we're now on the 2nd day and my ability to review alerts and detections is still working including audio.

That said, this may (I can't say I tested before fully as it was so tempermental) have introduced a decent audio delay, maybe 1-2s. Is there a way to try to get that closer to sync?

hawkeye217 Oct 16, 2024

You could try a few things.

First, try using go2rtc's aac transcoder:

go2rtc:
  streams:
    Front:
      - ffmpeg:rtsp://user:[email protected]:554/h264Preview_01_main#video=copy#audio=aac
    Front_sub:
      - ffmpeg:rtsp://user:[email protected]:554/h264Preview_01_sub#video=copy#audio=aac

If that still produces undesirable results, try using #async. I'm not sure if this parameter still exists in the current go2rtc version, though.

go2rtc:
  streams:
    Front:
      - ffmpeg:rtsp://user:[email protected]:554/h264Preview_01_main#video=copy#audio=aac#async
    Front_sub:
      - ffmpeg:rtsp://user:[email protected]:554/h264Preview_01_sub#video=copy#audio=aac#async

the audio coming from the camera is already AAC, so would the first one do anything differently? I'll try async and see if it still exists.

Any thought to trying the restream low latency flag?

hawkeye217 Oct 16, 2024

Even if it's already AAC, ffmpeg could remux and reorder. I'd certainly try transcoding.

The low latency restream preset is appropriate for extremely solid (wired) camera connections.
