I raised an issue a few weeks back on post # 3,633 ([8.0.2e] LibreELEC 8.0 for S905/S905X) concerning random stutter during 25p content playback (23.976p and 24p content are unaffected). This content is all HEVC and 720p resolution. My entire library is 720p and 98% is HEVC.
I have narrowed it down to the change between releases 8.0.1l and 8.0.2a. I have tested several files at both releases and so far I see perfect playback at 8.0.1l, but random stuttering at 8.0.2a and all subsequent releases through 'e' on the same files.
The big change at 8.0.2a was that Kodi was upgraded from v17.1 to v17.3 and the kernel was changed back to MM. I don't know if this is the cause but my testing does seem to suggest that this is where the issue started. The stutters are random in nature (not predictable like the 40 second micro stutter). It also appears that release 8.0.1a plays back the files perfectly (this was the last MM release before the experimental kernel changes done from 8.0.1b thru 8.0.1l)
Should I upload a debug log (or a sample of the log around the time that the stuttering occurs)?
Strange that only 25p is affected,,,,,,,,,,,,,,,,,,,,,,, I should add that the files playback at the correct TV hertz rate (i.e. at 24hz for 23.976p and 24p and 50Hz for 25p).
I've posted a log here:- FGDg
This was using the latest dev version uploaded yesterday. The stutters are a lot less noticeable (so far) with this version - sometimes very difficult to see them. I don't know if the log will shed any light. I did test a x264 25p 720p file and also noticed stuttering - as said, it's difficult to pin down the cause as it's so random and sometimes it can be 20 minutes or more before it happens. Most of the time it happens within the first 10 minutes - but on all 25p content so far.
TIA
PS - I've no problem staying at 8.0.1l
