Trying to use a RPi 4B via composite to CRT TV as a local media player for HVEC / H.264 10 bit videos

[/RaspberryPi]

I've been working on this project to set-up my RPi4 4b (8gb) as a media player with a CRT TV. I am specifically having issues getting the Pi to playback HVEC (H.265) / H.264 10 bit videos in VLC. H.265 doesn't work at all (black screen) and h.264 10 bit videos play, but with a lot of visual artifacts and occasional lagging. I first tried Kodi (LibreElec) and OSMC, but experienced a lot of lagging with those distros, even with lower bitrate H.264 (1080p) videos. I read that LibreElec has an upstream version of FFmpeg that supports H.265, but it didn't seem to work for me. So I ended up running regular RPi OS with VLC.

My understanding is that HVEC and H.264 10 bit videos are supported with the appropriate drivers. However, I still can't get the encoding to work despite following multiple forum threads and blog posts online. Is this because I'm using a composite signal vs. HDMI?

Hardware: RPi4 4b (8gb) to CRT TV via TRRS composite cable. Media is being played back locally via a 4 TB powered external desktop HDD (Western Digital).

Software: Raspberry Pi OS 32-bit with VLC

I downloaded the following libraries: libgles2-mesa libgles2-mesa-dev xorg-dev

My config.txt:

# For more options and information see # http://rpf.io/configtxt # Some settings may impact device functionality. See link above for details # uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment the following to adjust overscan.
