camera became unresponsive after a week of normal performance

[sergeymaysak]

Hi All,

I've installed latest custom fw on my wyze v2 cam a week ago. The start was very promising. i've got 1600x900 rtsp h264, integration with synology, camera in home assistant and mqtt switches and snapshot camera on motion and ffmpeg cam for homebridge. Great! and really working.

However, device became very unresponsive after 6 days. it looks like cpu is under heavy load constantly. web ui is mostly unaccessible, video streams as well (i'm not able to open rtsp stream in vlc - vlc hangs). I've tried to inspect contents of sdcard - its mostly empty. i.e there is nothing that close to fill up the card. I use 64Gb sd card.
Reboot does not help. So far I try to detect what makes cpu busy but w/o no luck so far. Any advice where to look are welcome.

Also tried to:

• disable motion detection completely
• disable audio
• change video resolution to lower with less fps
• disable video recording

Nothing helps. (

If anybody knows how to fix this, please share.

Best, Sergiy

I recognized similar behaviors. But not that bad. In my case sometimes the stream hangs. And so does ffmpeg, which records the stream from another machine. I even switched off logging, which does happen from /system/sdcard/controlscripts/rtsp-h264 to the sdcard.

When I have updated the cam through web update, it gets better for me. But after a couple of days I get the same issues again.

restarting the cam, in some cases, the router, usually fixes it for me.

I've extracted sdcard and run First Aid for it on mac at disk utility. It found a lot of issues in file systems. Well, I've just reformatted sdcard again and copied contents of firmware_mode on it again.

It looks like helped to web UI.
But video stream is lost just after minute of so of work after restart.
My logcat shows the following after restart:

I've found it was already discussed here: EliasKotlyar/Xiaomi-Dafang-Software#21

Not sure what's next...

closing this as resolved by repairing and reformatting sdcard.
