Tanix TX6 LIbreelec 12.0.0 video stuttering problem

Can you post the sample file somewhere so we can have a look at it?

Sure, try here: https://file.io/nD7cfTqFjux0 or here https://easyupload.io/cf79c7

It's a good test file because it has a lot of smooth panning shots, any stutters stick out like a sore thumb, and again to note this played fine on Allwinner H6 on LE11 (and 12 Beta1/11.95.1), but now struggling on LE12 final so it's a recent regression to bisect.

It plays on all the devices I have to hand, none of which has an H6 chip. I need to rummage in cupboard to find one..

Cool, but yep would be good if someone else could test the file on an LE12/H6 setup.

I've tried the test file on LE12/Tanix TX6 and it does play "jerky". I thought the bit where the helicopter flies overhead was the unmissable showcase for the problem. I've played it on other (non LE) devices and it's buttery smooth.

hello, im having same issue since a couple of days ago, but not always (so maybe problem there before and i didnt see it before), it happends suddenly, some times video "break" images when OSD is up and dissapear when OSD is gone, others is just the contrary, video starts to show "broken" images, bands, jumps, flashes that stops when OSD is opened.

just stopping playback and starting again problem dissapear, have to say that for me, setting to EGL does make no difference

hardaware is orange pi3 lts, install is 12.0 "jernej ethernet patch"

Bingo, not just my box then. Thanks!

Let's hope that chewitt's rummaging was fruitful and he can sort it out.

hi there, the issue seems to be something about subtitles i will explain it: if movie need subs in some pars, subs are on by default, screen flickers, but if subs are not required (some other parts of the movie in my mother language i.e.) subs stops, its ok, but still enabled, just setting them to none, flicker stops.

Tbh, most overlays affect the video performance with PRIME rendering on the Allwinner H6.

yes, it seems to be overlays issue

Is there any more news regarding the fix yet?

I'd sort of given up on my TX6 but the latest nightly Libreelec 13 (Kodi 22 alpha) is a big step forward imho. Only thing I've found is glitchy playback of SD TV streams that are mpeg2 in a day's testing. To me this is insignificant. I'd recommend anyone to try it.

Thanks to Libreelec team for this.

Yep, I'll wait for the LE13 betas before I revisit my TX6 (back in the box for now, don't want to bin it just yet).

Try to install latest LE12 nightly. There were some fixes about video playback.

If anyone is interested, I can also post WIP images where video decoding is re-done and TX6 is capable of smooth 4k@60 HEVC playback.
