    Hi!


    As I was reading the latest threads, I realized many users don't know there's Libreelec 19.8 with Kernel 5 with Astrometa DVB-C driver support.

    Here's the link: Index of /builds/master/


    Please note, this is an update pack only, not a full img also it is not official, so bugs and incompatibility issues might be present.

    To be honest, I don't remember how I installed it, but as far as I remember:

    Just install the official build with the downloader and get the latest 19.8 update from the link above.

    When it booted I used the update manual via Samba share described on this page:

    Update LibreELEC [LibreELEC.wiki]


    I hope it helped, if I was wrong, then correct me!

    Cheers. :*

    • Tell us the complete steps how to face the issue, so we can try to reproduce:
    • Description: I installed libreelec 9.1.002 (stable) and after first boot I updated to the version above. I needed, because my DVB-C dongle has correct firmware only in kernel 5.0 or above. and it works :) . I have set up TVheadend and I was happy, but watching HD DVB-C stream for a minute, the pi starts shouting about it's temperature. After a minute watch the temperature went up to 179 F degrees. I have a passive cooling sink on both GPU and CPU. I never experienced this quick heat rise. The sinks itselves was quite hot. The idle temp is 135 F. During stream playback the cpu usage was not more than 20-40 % per core. If you need any more information, I'm happy to help.

    Additionally to the above, if you are facing video playback issues:

    UPDATE:

    As I'm in Hungary, I went to Celsius and I was playing with settings. I managed to take down the temperature, but the problem is not solved.

    - 1st.: with default TVHeadend settings @ 720p with HD stream 30% CPU = 82 Celsius (case, heatsink, no fan)

    - 2nd.: passthrough TVHeadend setting @720p with HD stream : 10-25% CPU = 73 Celsius (case, heatsink, no fan)

    - 3rd.: passthrough TVHeadend setting @800x600 with HD stream : 10-25% CPU = 68 Celsius (case, heatsink, no fan)

    - 4th.: passthrough TVHeadend setting @800x600 with SD stream : 2-15% CPU = 62 Celsius (case, heatsink, no fan)

    - 5th.: passthrough TVHeadend setting @1080p with SD stream : 10-35% CPU = 68 Celsius (case, heatsink, no fan)

    - 6th.: passthrough TVHeadend setting @1080p with HD stream : 10-40% CPU = 71 Celsius (case, heatsink, no fan)

    (room temperature 29-30 Celsius, very hot here now)


    Very interesting, set TVH to passthrough the stream makes a big difference, although I think that conversion is going to the GPU according to the cpu usage. (Well, I hope I have set it to passthrough, for the second time I did not find the setting, so many setting... :) ) For some reason (looking at the 2nd and the 6th tests) it's not very accurate. Anyways, I'm not sure how to keep the temp below 60, as far as I know that is the limit of the safe usage.
