I've been a Kodi user for years. Was running Kodi 18.7, which was the latest one on the Raspbian (Debian 10). RPi 4 is connected over HDMI directly to AV receiver. Recently bought a new AV receiver and noticed that sources with Dolby Digital+ (E-AC-3) were not outputting any audio when passthrough was enabled. As soon as I disabled passthrough for for E-AC-3 audio was working as PCM. After some googling found that Kodi 19 had some fixes related to E-AC-3 and updated to Debian 11 from where I got Kodi 19 via apt install. Now, audio started to work as expected (yay!), however all content as h.265 did not show any video, just audio. Playing h.265 content was not problematic on Kodi 18. Decided to upgrade to Debian 12 to get Kodi 20, which I'm currently running. Now video and audio is playing, but doesn't matter if source is h.265 or something else then video framerate is unbearable (feels like 10 FPS or something). Doesn't matter if source is 1080p or 4K.
In /boot/config.txt I have these lines:
dtoverlay=vc4-kms-v3d,cma-448
dtoverlay=rpivid-v4l2
hdmi_enable_4kp60=1
I've tried almost everything by now. Any ideas why these problems exist? Any suggestions what should I try next?
