vcgencmd measure_temp command returns anywhere from 80 to 84.9'C during playback.
The RPi 3 currently sits in the aluminum Flirc Kodi case.
This shouldn't happen with Flirc case. Looks like there is no contact at all with a SoC and a built-in heat sink.
I just tested with kernel 4.18.0 - the issue seem to be fixed - I blocked the signal from LNB and when the signal came back - tuner was able to lock it.
Nevermind, I did more testing and this issue randomly pops up with any kernel including 4.9.
However, with kernel 4.18 I encountered another issue - VDR (or VNSI) does not seem to function - I don't get any picture.
CvH or anyone - can you test if VDR/VNSI works on your hardware with kernel 4.18?
I want to test with those mutex commits reverted - I tried to revert on kernel 4.14 but I have no idea how to do this. 
After upgrading from kernel 4.9.80 to 4.14.61 on my RPi3 I noticed this:
After the signal is lost (e.g. due to bad weather) and when it comes back - the tuner (DVBSky S960) does not lock the signal anymore. A reboot is required. I was able to reproduce this issue multiple times by blocking the signal from the LNB. Never had this issue with kernel 4.9.
Nice, is this going to get fixed in future builds? I miss my Godfather Collection...
Use Milhouse builds for now. There is no such issue in his builds.
This build does not play DVDs (VIDEO_TS folders).
21:22:27.076 T:1567503216 ERROR: Error on dvdnav_openI came across this issue when building my own RPi2 images from current LE master. I used Ubuntu 16.04 as a build host.
There are 2 ways to fix this:
- do not enable LTO for building Kodi
or
- build in Ubuntu 17.10 or 18.04.
I am not aware of any other hardware that will give you similar HDMI config options.
Those tweaks are for raspberry pi only.
Manually edit diseqc.conf.
Try to remove RAM overclocking
sdram_freq=400The HW VC1 and MPEG-2 codecs are irrelevant. VP9 is decoded with ffmpeg on Rpi. The performance of software decoded VP9 and HEVC is massively improved in Kodi 18.
It plays fine on Rpi3 with LE 9 (current Milhouse build).
VDR config plugin never worked for me either. Just download channels.conf from the internet.
There are no usable Kodi 17 builds afaik. Rockchip support in LE is more or less experimental - there are no guarantees that it will ever work well like Rpi3.
Try "arm_freq=1300".
8-bit HEVC will work. You will need Windows for 10-bit HEVC.
