I'm having issues with playing videos on my tablet - Samsung Galaxy Tab A8 (SM-X200), 4GB Ram, Android 13.
All this relates to playing videos stored in my local network, not any streaming from the internet.
At first there were occasional buffer issues with 1080p videos, where the video stopped, the loading circle appeared and on top it showed the "buffering... x%". This could take up to several dozen seconds with the percentage sometimes fluctuating back and forth until it would continue.
Then there's another phenomenon, where the video also stops for a few frames and then continues - by speeding up the missed out seconds - without showing the "buffering" message. This applies to 720p as well. This is what I mostly experience at the moment. The aforementioned buffering with the loading circle seems less/gone with higher memorysize in advanced settings.
I think this part of the log (full log here) refers to those issues. This can happen several times in a minute and then it's fine for an hour. Sometimes it might not happen at all. I couldn't find a common denominator for files where this happens and where it doesn't.
As you can see, this happened 30 times within three minutes.
I played a lot with the advanced settings, currently using
This is a bit extreme, but I went from low memory of just ~256mb with readfactor of 100 (onehundred) to more balanced values or lower/upper extremes at the same time. Nothing really solves it.
To my entire setup... the files are stored on my little home server (Win8-x64) thats connected via 1GBit LAN to the router. The files are shared as nfs-links via haneWIN NFS. I did this back in the day, when I had issues playing BluRay Remuxes with Kodi on my first RaspberryPi (1. gen - 100mbit LAN), when sharing via smb and this completely solved it and I never had any issues ever since.
The tablet is connected via Wifi-5G to the router with short distance to it. 2.4G and 5G channels are separated to guarantee it uses 5G.
There aren't many apps running in the background, I use it to watch videos while in the kitchen or to read ebooks and nothing else. I can stream youtube or twitch streams in 1080p-60 without any issues, which go up to 8mbit/s.
While surely x264 would have higher peaks, the readfactor and large memory should allow generously to compensate for those higher demands, at least in theory.
I regularily restart the tablet and clear the Kodi cache, but to no effect.
The tablet might not be top of the line, but I don't see why it would struggle with those issues in terms of processing power.
With the wifi I don't think I can improve anything, at least not in conventional ways. I already put the tablet on realtime-prioritization in the router settings, but I doubt that has much influence in the local network. Also there's no other devices active that would be able to hog the bandwidth.
I'm running out of ideas and hope, some of you might have experienced - and solved - this.
I know haneWin has some settings for chunk sizes or so, but I didn't play around with that yet, or know what I should try.
In the end I don't even know what the bottleneck is. Is it the wifi? The tablet? Kodi's buffer management?
If anyone can help, I'd greatly appreciate it.
