My Device [Dell Wyse 5070 ThinClient

HDR is not possible with this. DisplayPort 1.2a can't output HDR metadata

Could be a dying NAND flash. Try to run LE from a USB drive.

I use ffmpeg 4.4 which is not even merged to a current LE master. That is the most likely cause of the audio issue.

Doesn't work in regards to what?

I tried a bunch of HDR sample files. TV reports that no HDR present. Can't run modetest right now because I already moved my AMD Athlon 200GE box to another room.

lrusak It works fine on Gemini Lake. Doesn't work on AMD Vega 3.

this build outputs is RGB 36bit for everything

It outputs RGB 12-bit at up to 4K/30Hz and RGB 8-bit at 4K 50/60Hz.

It can be forced to output YCbCr 4:4:4 instead of RGB but there is no point.

5980 is a completely different hardware and different drivers.

It only turns off very briefly when I stop watching a channel and than right back on again

I use VDR/VNSI. It constantly scans transponders for EPG, so the LED is always on. It should turn off when there is no signal. Also, there is a short blink when switching from one frequency to another.

Does it turn off then there is no signal from antenna?

Quote from Forage

The tuner is also constantly warm

That's normal. Same with 5520SE.

I don't know if it works on 5580 but on 5520SE I enabled the green lock LED with this:

My build of tvheadend should not be used with LE nightlies.

HDR10, HLG should work on that board. Dolby Vision will never work on mainline linux.

RE: Intel true 10bits/HEVC/HDR support... ?

Yes, Tvheadend that was compiled for X11 version of LE doesn't work.
I compiled Tvheadend 4.2 and 4.3 that will work with my builds.

I don't know what broke it, so no idea.

New build:

- Kodi Matrix updated to 01033a8 + HDR patches

- Current LE master ebf2ee0

- Linux 5.14.1

- FFmpeg 4.4 updated to bf87bdd + AV1 fixes

- included support for AV1 VAAPI HW decode (Intel RKL/TGL and newer)

- AMD support is included this time (radeonsi mesa driver)

LibreELEC-Generic.x86_64-11.0-devel-20210904012247-ebf2ee0.img.gz

Kaby Lake/Apollo Lake will work only if the board has HDMI 2.0 (via DP->HDMI LSPCON chip). Native HDMI 1.4 port will not output HDR.

Anything with HDMI 2.0 onboard should work.

edit projects/RPi/devices/RPi4/linux/linux.arm.conf, add the line CONFIG_DVB_USB_TBS5520SE=m.

Make the same change to linux.aarch64.conf file.

Just compile an image with my patch. Copy it to packages/linux/patches/raspberrypi and edit projects/RPi/devices/RPi4/linux/linux.arm.conf, add the line CONFIG_DVB_USB_TBS5520SE=m.
