Your config wrong. You don't have aqara_g3 stream

Hi, I have the same camera and I'm facing this issue as well, but I've somewhat narrowed down the cause after some debugging.

In the videoToMedia() helper function, two CodecParams are reported for this camera, which are equivalent to H.264 Main Profile Level 3.1 and H.264 Main Profile Level 4.0 respectively (see print below).

core.Codec{Name:"H264", ClockRate:0x15f90, Channels:0x0, FmtpLine:"profile-level-id=4D001F", PayloadType:0x0}
core.Codec{Name:"H264", ClockRate:0x15f90, Channels:0x0, FmtpLine:"profile-level-id=4D0028", PayloadType:0x0}

The trackToVideo() helper subsequently uses the first available level, which is Level 3.1. However, that doesn't actually appear to work, and instead it is Level 4.0 that results in a successful stream.

One way to test this with the hardware is to temporarily change this line to hardcode camera.VideoCodecLevel40 instead:

go2rtc/pkg/homekit/helpers.go

Line 98 in 7036d19

Level: []byte{level},

Let me know if more details are required - at this point I'm not sure if the camera is wrongly reporting its support for Level 3.1.

@bebaton14 you have VERY old FFmpeg

[AlexxIT]

@duncanleo I have tested G2H Pro. And haven't problem with default go2rtc behaviour. All works fine.
Model CH-C01, firmware 4.0.7_0006.

[AlexxIT]

Thanks @duncanleo. You was right. Some bug in G2H firmware. Can't play stream with low level.

https://github.com/AlexxIT/go2rtc/releases/tag/v1.8.5

PS. No problem with G2H Pro

[duncanleo]

@AlexxIT thank you for fixing the issue!
