Posted my debug logs, please advise jernej if any more info is required:

dmesg:

Again to note, this box doesn't seem to have any default working IR config (even my MCE RC6 remote doesn't work with it OotB), it'll reboot/restart fine, but doesn't shutdown or start (from IR or WeChip G20 RF dongle), no WiFi either but I understand this.

Otherwise it's an excellent box, a genuine Samsung CJNB4R 64GB eMMC and great thermals (rarely above 55'C, even under heavy load)

My problem is if I power off I get stuck on a black screen and can not power it back on without unplugging the device and plugging it back in.

Tbh my T95 Max does this also, both with the TX6 stable/nightly images and TX6 Mini test image, it doesn't shut down properly (HDMI is still powered, screen is grey not black).

Looking forward to the upcoming RPi4B+ vacuum tube edition.

I use an AMD 5950X to encode stuff with in Handbrake, I dread to think how long some of the jobs would take an RPi4

Also for <=1080p files H.264 is still often optimal for filesize/quality compared to H.265.

in theory !

125 MB/s minus overhead := "effective data rate"

Indeed, it's more like 90MB/s in reality.

I've just tested this myself on my T95 Max (w/LibreELEC 10.0.1 stable), to confirm you can't rotate the video via DTP, but it works via EGL:

Note this is obviously just the video, not the whole display UI.

oh, I wasn't aware that RPi 3 has only 100 mbit LAN.

RPi3 does, RPi3B+ has a Gigabit controller connected to the USB 2.0 bus, so it's a bit faster (so 480 Mbps, but in reality more like ~300 Mbps)

Quote from JoeAverage

any pointer ?

Try disabling DRM PRIME and letting it fall back to VAAPI, is HW decoding shown then?

H.264 8/10bit decoding 'should' be supported by your IGP though.

Quote from surveyor81

I tried it with lubuntu but it doesn't show me the option of 60hz. Max option is 30hz

Could also be a cable issue, so try another if you can?

Quote from JoeAverage

questions:

why do I see "ff-h264-drm_prime (SW) ?

does it mean all GPU-HW-Features are switched off ?

Yes, but only for that particular codec depending on HW capabilities, for example VP9 profile 1 might show (HW) but VP9 profile 2 might show (SW) or the hardware decoder might support 8bit colour and not 10bit (which is fairly common).

I just picked up a dirt cheap Allwinner H6 TV Box (T95 Max) just to experiment with and not really expecting it to be perfect with any of the latest TX6 images, but it works great (apart from IR and WiFi, but hey) and I'm pleasantly surprised tbh, good job.

I am trying to make a new install for my Pi 3, but I am having difficulties. my laptop runs Linux Mint 19.1

It should be straightforward if you already have the gnome-disk-utility installed, just download the image instead, and then 'restore disk image' to the card/drive you wish to use.

The hardware video decoder in the IGP is normally enough for processing, the CPU performance is only relevant for running heavier skins etc, but a couple of cores (2C/4T) is usually fine.

Anything >Intel Apollo/Kaby Lake should be okay for HDR, and for AMD the Vega based APU's are good too (if overkill on performance per watt).

I've been using the below build on my Hades Canyon NUC system (Vega M GPU) and it's been great with HDR so far:

Intel NUC 8th Gen: SMP’s HDR build: Atmos Skip fix?

I have been using the smp HDR LibreElec HDR build on my Intel NUC8i3BEK for quite a while with excellent results. Thanks smp .

Kodi Git has just added a fix for a long-standing issue that causes skipping in high bitrate Atmos streams. Skipping can be so bad some titles are unplayable (examples: The Beatles Abbey Road album and Free Guy movie) . This fix resolves the issue with changes to Kodi’s audio syncing.

Here is the Matrix branch fix, there’s one for V20 master too:

Yep, that new build is really good so far. RPi4 is delivering a top notch experience now, credit to everyone involved.

Quote from loki7777

So what is good, will be supported for a while and will not cost as much as Nvidia?:)

Intel NUC and equivalent devices, or the trusty RPi4.

Everything else will need a bit more homework and research tbh.

I'm still a bit concerned about AV1 support in general tbh, the two main mobile SoC manufacturers (Qualcomm and Apple) still don't support it in their latest hardware, and until they do it'll struggle to gain much traction IMHO.

...ASRock J4205-ITX board (Apollo Lake w/1.77.93 LSPCON firmware)

Also tested the 1.78.4.0.4 firmware from here: https://www.intel.com/content/www/us…e-nuc8i7be.html

Had to double check it's the same MCDP2800 LSPCON, and it is: https://www.kinet-ic.com/mcdp2800/

Again, all updated fine and worked with HDR content switching fine also.
