I can confirm that. Tried also max. cpu stress without difference. For memory, I have 2/3 of cma and half of system memory free while the application is running.

I do not use audio, but I get this error message also sporadically using the `PyavOutput`: ``` 2025-08-08 19:58:54,266 DEBUG - Discarded non monotonically increasing dts: 19484976901

You can try pyav to write .mp4 directly from python, it has advantages with handling timestamps: https://github.com/raspberrypi/picamera2/blob/fb031cb49cb2af4dab7439be7a90784c9d3db1ab/picamera2/outputs/pyavoutput.py#L15-L18 Example: https://github.com/raspberrypi/picamera2/blob/main/examples/pyav_capture.py

Sorry, thought you were using ffmpeg explicit at some point. So the PyavOutput is giving you the > Timestamps are unset in a packet for stream 0. This is deprecated...

I encountered a similar problem which is probably caused by the same bug. After stripping down my code to a minimal example I also noticed the CameraManager and preview event...

@djhanove While testing the new firmware, I discovered a different issue, which looks similar at a first glance, but is different. With the affected firmware, my complex application stopped after...

Thank you, that sounds reasonable and explains what I observed. Skipping frames seems to be the only option for the encoder if exceeding the bitrate with max compression. I can...
