What happened?

As in the title: Previews on S22 Ultra Android 14 do not play with videos over 5min. I tested short videos and they work flawless. Also tried with a lent Pixel 8, and the same 5min+ videos preview without issue (even though rendering is slower on the Pixel 8 :D).
Any ideas how to fix it?

are you sure the 5 min is the main factor? what camera is the video file from? does it have gyro data? what resolution, codec?

Sorry for the late reply. Spend a whole afternoon making videos of various lengths, only to find out, that it's actually not related to the length...

So you were right. The resolution seems instead to be the problem. 4k videos (3840 x 2880 ) don't preview within the first few frames of pressing play.

Same videos run perfect at 2.7k (2688x2016) resolution.

Mind you this is all on S22 Ultra. On the other phone I tested (Pixel 8) 4k videos are not a problem.

Other video stats:
Lens profile: DJI Avata 2
Duration 8s
Framerate: 59.940, also tested with 50fps with same result
Codec: HEVC 115.34 (for 4k) HEVC 95.89Mbs (for 2.7k) -> is this maybe the source of the problem?
Pixel format: YUV420 10 bit
Contains gyro: yes

Ok go to Advanced and try different "Preview pipeline". Also does anything change when you disable stabilization?

Tried all combinations of preview settings. Preview also stops even if stabilization is switched off. Video plays normal with the build in video player, so I don't think, it's a codec problem either.

Try this apk https://github.com/gyroflow/gyroflow/actions/runs/8444901910/artifacts/1361449368

Tried the apk, but same behaviour. 2.7k videos run in preview with no issues, 4k videos run for 2-3 frames, then lock up.
Pixel 8 plays all without issues. It doesn't matter if I choose the "[wgpu] Adreno(tm) 730 (Vulkan)" or "CPU" option for the preview pipeline video processing, else I would have blamed it on the S22 GPU architecture. I'm going to make some anonymized videos tomorrow morning and post them for testing. Thanks for the quick response.

Here are 3 videos (4k 4:3 not working, 4k 16:9 working, 2.7k 4:3 working) and some screen recordings.

(I reset all setting to default in the app before doing the screen recordings)

How about this apk? https://github.com/gyroflow/gyroflow/actions/runs/8849189979/artifacts/1451192994

Still same behavior.
Btw: I just realized, that scrubbing though the whole video is possible, before pressing play. After pressing play, the video locks up again after a few frames. I added a new screen recording to the OneDrive, using the new apk.
