Bad Twitch playback on Raspberry Pi 2

1st Official Post

    Hi, I was looking at updating my OpenElec Kodi 17.3 pi setup, so I downloaded and flashed my SD card to the latest LibreElec.

    LibreELEC-RPi2.arm-8.2.5

    Problem is, playing Twitch 1080p stream, I get audio but laggy video playback. Reverting to a re-flash of OpenElec 8.0.4 resolves the issue, with the same stream. Output is HDMI to a Samsung TV.

    LibreElec has only the Twitch 2.2.4 plugin added, nothing else.

    Anyone else have this issue? Or any tips as to how to resolve?

    Thanks!

    No joy. With 8.90.003 same playback issues.

    I turned on debug logging and it shows 8.5fps while the twitch stream is being played. Playback is smooth for a second or two then starts to lag.

    CPU showed 4 cores, moderately used (CPU-KODI was ~50%)

    Which RPi? 2,3 or 3+?

    50% seems very high especially on 4 cores, so I'm guessing decoding.

    Stick with 8.90.003 and provide full debug logs (as explained in my signature), also the output of

    dmesg | paste

    top -b -n 30 | paste (When twitch is running)

    You could also try increasing the buffer in .kodi/userdate/advancedsettings.xml - but this is a last resort as the default settings should suffice.

    Code
    <advancedsettings>  <cache>    <buffermode>1</buffermode>    <memorysize>262144000</memorysize>    <readfactor>20</readfactor>  </cache></advancedsettings>

    Note: This is the MAX. For 24/7 systems you'll need to reduce the memorysize as Kodi uses 3x this value.

    I have a feeling this could be due to python.twitch which hasn't been modified since 2016.

    I think the best you can do is stick with OpenElec or try lower resolutions is the twitch setting. There is an open ticket for lagging Here

    Thanks for that info. I added my 2c on the open ticket you provided.

    I do have a solution with sticking on OpenElec 17.3, but I would prefer to stay current, and the working OpenElec says it *should* work.
