LibreELEC H265 DOLBY: STREAM STALLED AFTER UPGRADE TO 10.0.2

sny78 · April 3, 2022 at 9:40 AM

Hey everyone,

maybe someone has a tip for me. After successfully upgrading my Pi3 (1GB Ram) to 10.0.2, I can no longer play local H265 videos.

Sound works great, but video playback stalls every 1-2min.

Code

<advancedsettings>
  <cache>
    <buffermode>2</buffermode>
    <memorysize>99614720</memorysize>
    <readfactor>4</readfactor>
  </cache>
</advancedsettings>

Note that GPU accelerated H265 decoding is no longer available in LE 10 and future versions. If this is important to you stay at LE 9.2

H265 is software decoded and RPi2/3 simply don't have enough CPU power to do that.

so long,

Your micro log snippet shows nothing of use, but LE9.2 and earlier have custom optimisations for software HEVC playback on RPi hardware and LE10/LE11 do not have this, and as there is a general mission to only run upstream code (and avoid 100k line custom patches) there are no plans to add it back (the clever but hacky patches are not upstreamable). So RPi2/3 will still software decode HEVC content, but you prob. can't achieve HD resolutions.

Thanks a lot, just downgraded to 9.2 and everything is working fine. Thanks!
