Latest build Rpi4 - Suffers pausing randomly and micro stutter video playback

A1RFORCE1 · November 15, 2021 at 11:06 AM

In the latest nightly builds, the video playback freezes for an micro second and fast forwards to catch up..The audio stream continues as normal. Also the playback is pausing randomly like if the buffer ran out, but no log entry appears in the debug log it's just pausing.

Cool, Thanxzz. but the pausing issue is with all the video's, I don't think this is related to VC1

You say "in the latest nightly builds".

Does it also occur in older nightly builds, or 10.0.1?

Good question, I ll run a test to verify this.

- is it still possible to download the latest LE 10 nightly version?

I see similar behaviour (LibreELEC-RPi4.arm-11.0-nightly-20211117-df8716a.tar):

video freezes for a few seconds while audio continues, then suddenly video catches up. When the video has finished playing the last frame is still displayed until I explicitly stop it.
