Hi,
question might have been asked, but I can not find an answer easy
(especially for my use case).

I have very bad video performance on RPi4 + Debian + Kodi 18.9
IT is as if the video acceleration is not working. TBH I did not check
if /dev/dri exists and has the right permissions, but before I do that can
you share your experience and give me some idea where to start.

I found so far only BS with help of google and not exactly related to RPi4

thank you in advance

Not realy any help but my Pi3B+ running OSMC was perfect
My Pi4B which is raspberrypios + kodi also plays without any issues.

Stock debian is probably missing some proprietary broadcom blobs

Yes. All I know is that you only get hardware acceleration with the
official RPi / Broadcom stack. Kodi on RaspiOS 32-bit should be good, I
think, or else the specialised Kodi image LibreElec as linked from https://www.raspberrypi.org/software/operating-systems/#third-party-software

But I never tried it so this is definitely not expert advice.

(Not 64-bit RaspiOS because that's in beta and last I checked video
accel was one thing not working, or not well.)

Great!
Thank you very much!

Can I put one of these mentioned above on a NFS root, or there are issues to expect?
I prefer to run the RPi4 diskless.

thank you again in advance

LibreElec worked perfectly well and fast even on a RPi2, on a Pi4 it is
working even better here at my home, and with the advantage of built-in
h265 decoding through the graphics chip, so it's definitely well worth a
try.

Just for the record:
Unfortunately the image assumes there is SD card with squashfs that it wants
to mount and fails if I put the files on the NFS.
Do you know where exactly this is located (what is the initrd)?

thanks in advance
