Long(ish) video capture produces stutters
This may actually be a kernel issue because the behaviour is different between PureOS (running 6.3) and Mobian (running 6.1).
The issue can be reproduced the following way:
- Start recording a video (rear camera in my case - I haven't checked with front camera)
- Observe the preview freezing every now and then for variable amounts of time (t \element [0.2; 3] seconds)
- These stutters are also in the video file (probably this is obvious)
- This even happens for relatively short videos of ~30s (so should be easy to reproduce)
- This also happens when not thermally throttled (i.e. coming out of suspend and starting to record shortly afterwards)
However on Mobian these issues do not seem to manifest (this strongly?)
If desired I can provide some video footage
/cc @martin.kepplinger because it may be a kernel issue (I believe millipixels in Mobian and PureOS is the same version - TODO need to recheck)
