Yes quite likely, :-) though if you move the work from the CPU to the GPU, then the work is still being done, just being shared out more, so who knows, but from my experience the chip temp does seem to be lower now, (while playing HEVC) especially if you are not particularly stressing it, which in my case is most of the time, my test files are way above the quality setting I would normally use for every day use, normal usage will now only prompt 50-60% CPU max usage, which is almost bound to help with temperatures.  ;-)

One of my HEVC 10-bit 1080p videos stopped working with build #1010. I can upload a sample if needed.

RE: LibreELEC Testbuilds for RaspberryPi (Kodi 18.0) - dantist - 2017-10-11

I'm currently ripping a Bluray series to MKV files so I can watch it with Kodi. It's all working well, but I have one episode so far where LibreELEC uses the second audio stream (English) instead of the first one (German). Other players like VLC handle the file correctly. The VLC codec informations are 100% identical. I also scanned the files with "MediaArea MediaInfo" which also gives identical results.

Any idea what could be the reason for this?

Edit: Rescanning the library did fix this. I guess you can't just replace older files with new ones. Maybe Kodi uses the audio track information it found during the initial scan and ignores the actual audio track information when starting a video?

I upgraded from #0922 to #1010 and watching a HEVC concert today, saw the overheat icon for the first time in a long time. It only lasted a minute, but it is not something I have seen recently with these beta builds and not on that specific file in a long time.

I have a file that now requires more gpu mem than before. Can you check if increasing gpu mem fixes your issue?
If it still fails with, say, gpu_mem=512 then post a sample.

I have asked John to look into the increased memory usage to see if it can be avoided.

ffmpeg normally achieves multi-core parallelism by decoding multiple frames in parallel.
But sometimes due to dependencies this is not possible (e.g. frames depending on an I frame that is currently being decoded).
In this case you may see kodi dropping frames even though cpu is much less than 400% (4 cores maxed).

The last update added some within-frame parallelism for files encoded with tiles or wpp (wavefront parallel processing) which can help this situation.
But it may make the 4 arm cores busier for short periods which may increase temperature.

Really the only solution is to improve cooling. The Flirc/Kodi case is highly recommended.
You may also find that decreasing arm_freq / over_voltage will keep temperatures down (and with the continued performance improvements that may be feasible).

Keep the sdram and core/v3d overclock as they don't affect heat as much as the arm and do provide a useful performance benefit.

Increasing gpu mem to 320 fixed it.

Thanks, I've commented out arm_freq=1300 and over_voltage=4, and I do already have gpu_mem_1024=320
My Pi's are mounted vertically in open air with heart sinks installed.

What were the ssh commands to show how many times the heat/governor has kicked in, and also to show how many dropped frames?

You can use "bcmstat.sh y" to monitor undervoltage, frequency cap and thermal throttle events.

(2017-10-12, 14:12)J_E_F_F Wrote: and also to show how many dropped frames?

You can enable the PlayerDebug overlay from ssh with:
Code:
kodi-send --action=playerdebug

or map "PlayerDebug" to a button on your remote.

Alternatively, add "<loglevel>1</loglevel>" in advancedsettings.xml, restart Kodi, then:
Code:
tail -F /storage/.kodi/temp/kodi.log | grep drop:
Total dropped and skipped frames will be reported when playback is ended. This has the advantage of not wasting CPU time displaying the overlay which can itself be the cause of dropped frames.

OK, this is really weird, if I comment out arm_freq and/or over_voltage, and reboot, Kodi just freezes, I cannot control it via remote (phone or usb/bluetooth)  if I set arm_freq=1200, the same thing, Kodi freezes and can't be controlled.  Is some other setting here linked/dependent on my arm_freq being 1300?

arm_freq=1300

Please test #1012 as this now includes the RTL8814AU driver. I just hope nothing new is broken with RTL8812AU.
