RPi 3 Video stuttering.

Hi, i've run LibreElec about 1-2 months, and all of sudden my h264/x264 files are starting to stutter badly. I'm running through Emby plugin (Direct Play).

I've never had these problems when i used OSMC on the Rpi 3. Dunno if this could be heat issue in the Rpi 3 or something else, suggestions are welcome!

Regards Brian.

Are you sure they are H264 and not H265?

Media dump of a video file would assist.

Yes sure, thats why i'm wondering about the stutter.

"Video stuttering..."

Since we have no magic crystal ball here, please start with providing a kodi.log file.

I know if you're gonna dig deeper a log is needed. But i asked without logs, to get to know whether this was some obscure known problem with rpi 3 and libreelec.

Ill try to find out how to log and post it.

And maybe video stuttering isnt the best way to put, it actually pauses in several seconds 5-10 before continuing playback..

Hmm. Still suffering from major lag.. Tried the krypton beta, and now its getting worse.. maybe expected.. here's a snip of my log where playing back a file.

I'm using the emby plugin in direct play via smb share. So no transcoding is going on... This is wierd.. My rpi 1 never had issues playing anything..

Post a complete debug enabled log (use a paste site).

Your log does have some Emby compaints.

I'd suggest disabling Emby and first test playback of the file locally (e.g. copy to sdcard or locally attached USB stick).
If that is okay then try playing from a network share (without using Emby).

Testing with a clean install may be the best option if you have a spare sdcard.

Hi again,

First of all, - i fixed it :-).. It seems it was a stupid switch that acted up. I restarted the switch, and now it plays fine again. I hope, -haven't tried a whole movie yet.

Before i tried this i moved /storage to a USB stick, and edited the cmdline.txt to run /storage from the USB. I also tried playing directly via smb (not through emby addon) and it was the same.

I do still get the emby.kodimonitor and emby.player in my logs, but i think this may be due to the fact that i'm not running emby plugin in Add-on mode but Native(direct paths). This maybe a dumb choice, but i wanted to make sure it's not transcoding on my emby server..

Anyway, thank you all for your replies and help!
