Stuttering after pause or black screen

Single Board Computers Odroid N2/N2Plus/C4

Hi,
I have an odd issue with 4k video on my Odroid N2.

I have only seen the issue on 4k hevc vidoes, not on any 720p or 1080p content.

If I pause the video, or if the video fades to a completely black screen during the playback, the video starts to stutter and the audio goes out of sync. If I skip back or ahead 10 seconds the issue dissapears until I pause again or another completely black sequence of the film.

Anyone seen anything similar, or has ideas for a fix?

Please elaborate more when posting issues.

We need to know what version you are using at the very least.

I have the issue too.
Odroid n2+
19.5 nightly,
After i pause the video and resume it starts stuttering. If i stop the video and resume it plays normally again.
Can anybody help?

I have this problem too. When I pause video, then play it, stutters. 10 sec back helps.

Same here, Odroid n2+. Not directly related to 19.5 cause have it for a while now. Happening after putting on pause. Skipping 10 seconds back helps, so using that method for a while now.

Seems related to the Odroid n2(+).

Nope.
IĀ“m using both, N2 & N2+
No stuttering after pause

Try rolling back to 19.3. There are known stuttering bugs with N2+ on anything higher than 19.3 but nobody has been able to capture a debug of this issue.

Iā€™m having the same problem on N2+ with CE 19.5. The stutter is really light and corrected by a 10 sec skip but Iā€™d rather not having it at all.
Do you know if this issue is still there on CE20 ?
If you want debug log I can try to provide it

Managed to catch debug log and dmesg log when this happened. Odroid N2+ 4GB Running 19.5 Final

Snippet when this happened exactly. Started the movie, it was stuttering and did a 10sec backwards jump.

CE-19 is EOSD, try again with clean fresh CE-20 install.

I have had this happen with recent release of 20 also, but I did rollback to 19 because it was more stable.
I think this problem is still worth of taking a look.

13

Not on CE-19, no.

Iā€™ve seen the stutter start right after the first subtitle line (srt subs) appeared. Before that, just fine. Iā€™ll try and see if it is reproducible in CE-20 as well.

@Boulder, I think your log is better here than in the generic discussion on CE20, so here is the link: CoreELEC 20.0-Nexus Amlogic-ng Discussion - #115 by Boulder

FWIIW experiencing the same with the latest CE20.0 release build on my N2+: if there are subs in the stream (in my case the subs are embedded in the mkv) and the media paused, it starts to stutter after resuming. a -10s jump fixes it.

17

Iā€™ve had it on 20.1 nightly on a N2. Canā€™t recall the video it occurred on, but symptoms and fix are exactly as described.

As a complete hack ā€˜fixā€™ - can I suggest my addon - https://kodi.wiki/view/Add-on:Unpause_Jumpback - you can use that to automate the jump back after pause (get it to jump back after any pause, and jump back a minimal amount). That should at leat help, functionally speaking, until the problem is solved.

Confirming I also experience this issue on the N2+ on both 19 and 20, micro stutters after pause, the content is watchable but gets annoying.

yeah, iā€™ve always had this issue on the N2 on core elec leia/matrix, but i usually do a 30s back and then 10s forward (which always resyncs everything) because going back 10s would sometimes still have the stutter. iā€™ve noticed this on embedded and external subs downloaded by a4ksubtitles. i can post more when i upgrade to THE NEXUS but ainā€™t no thing.

I had written about this more than a year ago, but the devs havenā€™t been able to reproduce it, so i started to suspect something else might be causing it. Because while most people have N2, i have GT king pro, so it might not even be the device (at least not the only reason)

Just to check with others this is happening, i am using an LG 4k TV, and also passthrough audio to a Pioneer AVR. Wondering if either of these might be part of the reason. I dont suppose everyone with this problem has LG TV for example?
