MKV Video Freezes But Audio Continues To Play On ROC-RK3328-CC

RandomScrub · June 2, 2020 at 1:51 AM

Hello,

I'm experiencing this on my 2GB ROC-RK3328-CC (Renegade) board. I'm using the latest public build of LibreElec for the ROC-CC with the PlexKodiConnect addon. I've got both the RK3328 wired and the PC with Plex wired as well. In terms of cooling it has a Pimeroni Fan Shim on it and usually hovers around 58 degrees while playing videos.

What I've noticed is on some videos the video itself will freeze but the audio continues playing until eventually the video unfreezes and plays normally. The length of freeze and how often it happens is completely arbitrary for videos. But if it happens on a video it is repeatable in the exact same spots on the video every time.

The videos are 1080P HEVC 8/10 bit MKV format. The videos that I have issues with are anime with subtitles (ASS/PGS). Every other 1080P HEVC 8/10 bit video plays without hiccups (B99 for example).

The issue is replicable in the same spots regardless of whether the video is being played through PlexKodiConnect plugin or if I play it locally off of a USB device. If I play the same video on my Samsung Galaxy S10+ with Kodi it plays without issues. It plays on my computer with zero issues as well whether I play it through Kodi or MPC-HC.

I've included the Kodi.log file, Kodi.old file and the Mediainfo for one of the videos that I am able to replicate the issue with.

On the logs I enabled debugging logs as well as all of the specialized logs as well. Any help would be greatly appreciated. If I missed anything I can include it as well if needed.

Please edit your post and reduce the amount of linked files to two or three.

We'll ask for more logs, if needed.

PS: No reaction from your side, so I had to remove your links.

It's one log broken into 7 parts because of the file size limit of PasteBin.

Would attaching the full log and just leaving a couple links be okay as well?

Nobody will read 10 file links to help you. It's unreadable that way.

If somebody asks for files, you can post again.

PS: Thanks for editing your initial post.

Try the brand new LE 9.2.3.

RandomScrub · June 8, 2020 at 4:53 PM

Tried out 9.2.3. Looks like it has gotten a little bit better. Still have occasional stutters every now and then but they're fewer and far between.

Disable audio pass-through at Settings -> System -> Audio.

RandomScrub · June 10, 2020 at 2:43 AM

It's always been set to disabled if I'm not mistaken..

That looks buggy to me.

PS: I'm not sure whether the buggy kodi.log is related to your issue. The cause of your issue could also be a lack of hardware performance. Do you have options to overclock your device? Read here about HEVC and overclocking on RPi.

RandomScrub · June 14, 2020 at 1:38 AM

Yeah unfortunately it may just be the hardware isn't up to par for 1080p HEVC. I've dug around to see if there is a way to overclock my device, but I've been largely unsuccessful so far. Will keep digging around.

Thanks for your help.

advancedsettings.xml has some features to play with. I just have no clue if it affects your issue.
