Device Stops for 2S every 50S to 80S. Screen blanks and audio stops when playing music. It is occurring on nightly releases 20210218 20200219 and 20210220 and possibly earlier.

The device is a RPi4b with 2GB ram.

Please test with this build LibreELEC-RPi4.arm-9.80-devel-20210205165343-b642f3c.tar

If this has the same issue post debug logs: enable debug logging in kodi, reproduce the issues, then run "pastekodi" via ssh or use the logfile upload function in LibreELEC settings.

Note that screen blanking is often a sign of a bad HDMI cable - especially if you run at 4k resolution. Double-check that and also try running with kodi configured to 1920x1080 (that should work even with crappy HDMI cables).

How does one enable AAC to AC3 transcoding on the RPi4 LibreElec Nightlies? The option is not apparent. Do I need to install a plugin?

Change the settings level to advanced or expert and you'll see the options in Settings->System->Audio

I tried another similar file Downloads Page - Demolandia but that one stuttered too. I thought it might have been my NAS so played it locally from a USB; was smoother but still jumped around.

Yes, this is to be expected 4kp50/60 files won't play smooth.

-As someone mentioned before, DD+ pass-through doesn't work (but when disabled soundbar outputs as PCM)

-High frame rate (60 fps) videos don't work (memory issue or not supported yet? My settings perhaps?)

like the sony sword one: Sony: Swordsmith HDR UHD 4K Demo | 4K Media

DD+ passthrough is broken in kodi Garbled sound with DD+/EAC3 passthrough and official Dolby DD+ 7.1 sample · Issue #19182 · xbmc/xbmc · GitHub so leave that disabled

I could play back Sony Swordsmith here, so it would be good if you could post a "pastekodi" log.

50/60fps UHD is quite problematic though. The video driver can't output 4kp50/60 yet and the HEVC decoder in the RPi is also struggling with these files - player debug overlay shows that A/V sync is climbing up. 4kp24/30 files generally work fine though.

Passthrough is working well except on videos with 7.1 audio. I'm using passthrough via optical to a Marantz SR55000 receiver 5.1 speaker system. The media is HEVC 10 bit derived from a BlueRay. The Dolby 7.1 audio is being detected as a stereo audio source by the Amp. The voices in the video are mapped to the a surround channel and a barely audible. Media Info says the 8 channel mapping is "Channel layout : C L R Ls Rs Lb Rb LFE.

Media Info Audio.

Audio

ID : 2

Format : AAC LC

Format/Info : Advanced Audio Codec Low Complexity

With optical out only AC3 and DTS passthrough is supported. The mediainfo shows it's not a dolby digital but an AAC audio track - that can't be passed through at all, you have to enable AC3 transcoding (then kodi will transcode AAC to AC3 and you get 5.1 sound with your receiver).

dmesg says it's an RPi3B+

Solution: connect the DVD drive via a powered USB hub (or in the rare case the drive can be powered externally then do that).

The preferred and easiest way to post logs is to either use the upload logfile option in LibreELEC settings or to ssh into the RPi and enter "pastekodi".

Both variants will give you an URL, just post that URL here.

One question to all: Doe anybody knows, whether HDR is only available with HDCP 2.2? Is HDR passthrough not possible with HDCP 1.4 ?

HDR and HDCP are completely independent - RPi doesn't even have a certified trust path, so no widevine, HDCP etc.

RPi4 doesn't support 1366x768, see the official documentation Raspberry Pi 4 HDMI pipeline - Raspberry Pi Documentation

Try the workaround from there or just search for "RPi4 1366x768" and you'll find plenty of info and other possible workarounds.

Hias, the image that is tagged by its file on the above quote I just tried and I still don't have the hd audio formats ... although kodi on the TV has all the HD sudio formats (and the tagged build is the latest nightly build) any solutions?

No. As I already wrote 2 times, here RE: RPi4 testbuild with HDR support and here RE: RPi4 testbuild with HDR support there is no fix/solution available yet to get HD audio with your TV.

so long,

Hias

FYI: the HDR and HD audio changes of these testbuilds are now in LE master and included in the latest nightly build, so you can switch back to using nightlies.

It'll probably take a while until the colorspace and bit-depth issues are fixed, I'll report back when we've got something new to test.

so long,

Hias

The fix hasn't been written yet...

Hias

master/nighly is missing 2 commits from the latest testbuilds which further reduce the chance of audio dropouts - I'll include them in the next RPi kernel update.

http://ix.io/2PAw this is it, thank you in advance because this problem is fraustrating since the odi on android tv supports dolby atmos and dts hd and eac3 but on this libreelec build and the other libreelec build cant get thse formats

Thanks for the edid, this is a bug in the linux kernel's EDID passthrough format detection - I recently ran into that as well. I'll have a look if/how we can fix that.

linuxuser run this command on your RPi, then post the URL you got:

od -t x1 /sys/class/drm/card0-HDMI-A-1/edid | pastebinit

copy-and-paste that into putty/ssh and make sure all is in one line and exactly as above.

Quote from linuxuser

Hi again , do I need to grab this file from the tv or from the Raspberry pi 4? Thank you and also I tried but it says -sh edid.dat : not found

Use putty to connect to your RPi, enter that command, then use eg filezilla to copy the edid.dat file to your PC.

As an alternative you can run the following command via putty:

cat /sys/class/drm/card0-HDMI-A-1/edid > /storage/videos/edid.dat

then you can get to the edid.dat file via the "Videos" samba/windows share.

Edit: if you are using linux then use ssh root@IP-OF-YOUR-RPI instead of putty and "scp root@IP-OF-YOUR-RPI:~/edid.dat ." instead of filezilla.

so long,

Hias

linuxuser can you please grab the edid of your TV and upload it? Run

cat /sys/class/drm/card0-HDMI-A-1/edid > edid.dat

then upload edid.dat (you may need to ZIP it so attaching works in the forum software).

so long,

Hias

Yes. RPi4 uses the ARMv8 addons, RPi2 the ARMv7 ones.
