Slow video

[adolfocartagena]

Hello everyone.
When the application has been open for about 15 minutes it begins to look very slow, as if the FPS were dropping.

Thanks greetings

Hi!
Please check the CPU and memory utilization during playback.

Does this happen only if you have multiple streams visible at the same time?
Is your GPU intel?
Are you running with acceleration?

For me I get similar very gradual slowdowns, but only with multiple streams: Works good for at least 10 minutes, but the following day very slowed down. Will check CPU/GPU usage next time.

I am running on Debian 12 on Intel GPU (i5-5200U) with acceleration:

(Interestingly enough https://www.happytimesoft.com/products/onvif-client/index.html also has a leak in memory side so could have something to do with the system itself.)
