Question: video freezes

[RomchikL]

Hello!

Are there any restrictions (from the go2rtc server, browsers, or other platforms) on continuous video viewing from the server?

I can view a continuous video for a minute or two. Then the video freezes. At the same time, the log is good.

Check info page about your stream. If send/receive fields updates in time.

[RomchikL]

When the camera freezes, these fields also freeze.

[AlexxIT]

Well. I think the camera stops sending data. Probably thinks no one's connected to it. First, try to use ffmpeg in copy mode:

streams:
  camera1: ffmpeg:{link}#video=copy

[RomchikL]

Now the camera works continuously, but there are freezes for a few seconds. About twice a minute the camera freezes (and the send/receive fields also freeze), but then (after 5-20 sec) the camera continues to work without my help.

[AlexxIT]

Well. Maybe ffmpeg reconnects to your camera continuously. Have you check it in some other software? VLC maybe.

[RomchikL]

Ya, VLC: there are short friezes (~0.5-1 sec), but streaming latency is ~2 sec. The stream works for 0.5-3 minutes and the program stops the stream at all (the info page is "null").

Picture Entity card in HA: Here camera works as in the latter comment (a lot of friezes for 2-10 sec). The latency is minimal.

What camera model we talking about? Is it has brand mobile app?

[RomchikL]

Laxihub M3-TY with root, app - Smart life (Tuya). But the camera does not have internet access. I can't view the picture in this app. As a test, I can turn on internet access, but the stream will be through Tuya's server (not rtsp).

All of the camera hacks, I've looked at, have very awful RTSP protocol implementation...

Oh. It's you again #7 :)

[RomchikL]

@AlexxIT Yep, it's me again ;)

[AlexxIT]

Can you send direct link to hack, not to author profile? Maybe some article about it.

[RomchikL]

The direct link , but here are just the differences. The main hack is described here

add: I didn't change the firmware, I just got root and turned on onvif.

I experience similar issues with my streams.

It happens on the following devices, with a Reolink RLC-423 (https://reolink.com/us/product/rlc-423/) Samsung S7 FE (Wifi 6) Samsung a7 lite (Wifi 5) My computer (Ryzen 3900X, 1gbps, 2080s)

I can tell on the tablet, by using the GPU logs, that the gpu usage drops to 0 when the stream freeze, as if no more data is received.

I will be happy to provide logs and debugging time

[AlexxIT]

@maxi1134 Test your RTSP in other programms first. VLC, default Hass stream without WebRTC, ffmpeg copy mode.

[maxi1134]

Works perfectly in VLC!

[AlexxIT]

You need to test all my examples.

[AlexxIT]

Is the problem still relevant?

[RomchikL]

For me the problem is not relevant. After the update everything works fine, thanks!
