Car's blinking lights causes video recording to stutter and skip seconds

[Nord221]

I have a Wyze V3 flashed with the latest Thingino build 2/17/25 pointed at my driveway. Every time a car turns on their blinkers to temporarily park in front of my driveway it causes the RTSP stream and video recording to SD card to stutter and skip 2 to 6 seconds until the car turns off their blinkers. This only happens at night time.

I tried setting the Anti-Flicker setting from 0 to 2 but it made no difference. I came from using the official Wyze RTSP beta firmware and it did not have that issue. Is there any way to resolve this issue on Thingino?

car blinking changes a region of the screen and results in more data packed into each P-frame thus more data to process and transfer. given that it happens at night time, i would also think of a significant gain change due to changes in scene brightness which can trigger day/night mode switching.

try to identify where exactly the bottleneck is: data processing on the camera, data transfer over wifi, somewhere else. hijack your stock app to get access to the linux shell and compare the load and isp settings in similar conditions.

Thanks for your input on this. The scene definitely does change drastically between dark and light scene with each flash of the headlights.

The script to automatically switch between day and night mode is already disabled. Even if it was enabled I don't believe it would cause an immediate issue as it checks every 1 minute.

Could it have something to do with the light detection in thingino? Perhaps the sudden change between dark and light scenes within a second part causes some calculation to perform and thus hang the camera? Is it possible to stop this calculation?

As stated before the video is choppy both in RTSP and video recording to the SD card when the car blinks happen. The issue immediately stops when the car blinking stops. Issue does not occur in the Wyze RTSP beta firmware.

run streamer in foreground (killall prudynt; prudynt) and check the output when lights are flashing.

one little issue with wyze rtsp beta. they forgot to opensource it. lol
