h265 streams stuttering on intel NUC 5CPYH

Hey everyone,

I have an issue with h265 streams which are all stuttering. I am currently on 9.0.0 and the stuttering didn't happen on the 8.x builds of libreelec.

Do you know what can I do in order to improve the playback of h265 streams?

libreelec is running on the intel nuc 5CPYH which has braswell celeron CPU

Thanks

Same situation here

Downgraded to 8.2.5 and all is fine

Same here. Anyone playing h265 on 9.0.1 successfully?

You all should probably post a debuglog instead of a "me too" posting. We can't help without that log

OK can do- how do I find a log from video playback? Haven't done that before.

Also, after searching my issue quite a bit I'm concerned my issue with h265 is that the hardware is lacking, and processor is not fast enough for software decoding. Can anyone confirm/deny??

I am on an Intel Nuc 5CPYH.

Thanks

See post #29 in this thread:

Video stutter 25Hz Videoplayback with Hardwaredecoding Libreelec 9.0

Kodi 18.2 fixes the issue. Libreelec will incorporate Kodi 18.2 in the next update (due soon ?)

The update is out, and h265 is OK.

H265 10bit still stutters, but I'm now fairly sure this is due to my hardware/processor.

You can check that when you press "O" on your keyboard, this should show you the CPU and RAM usage... for me it did not work with with 9,0,1 so I came back to 8.2.5 where it works pretty fine...

I have NUC 6CAYH with J3455 processor, 2x4GB RAM, even when processor usage is bout 20% I am experiencing stuttering (I am playing over gbit ethernet from my Synology NAS using SAMBA bitrates are pretty small about since my videos are about 1GB / 1 hour movie/TV series).

So for now I am staying with 8.2.5

So I made and SD card install of new 9.2.2 the problem is still present for some of my TV shows that I stream over samba from my Synology NAS.

I have notice that the video was NOT choppy with 8.2.5

it was using:

Video decoder: ff-mpeg4(sw)

format: yuv420p

interlacing method: yadif=1:-1:1

now with 9.2.2 it is choppy:

Video decoder: ff-mpeg4(sw)

format: yuv420p

interlacing method: unknown

seems that the interlacing method makes the difference...
