Can't achieve smooth playback of AV1 video files on Ubuntu 23.10 with Nvidia RTX 4070 Ti

[ninbura]

I'm trying to playback AV1 files via VLC on Ubuntu 23.10 with an Nvidia RTX 4070 Ti, but haven't been able to achieve something even approximating smooth playback. The video will play for 1 second, and then freeze.

I had a similar issue on Windows until VLC version 3.0.19 was released, and now without changing any settings or additional work; video playback is flawless on Windows. I can't say the same for my machine running on Linux... With version 3.0.18 installed via apt I get visual video playback, but with the described playback performance (freezes). When I install VLC player version 3.0.20 via Flatpack I get black playback (no signal), but can still hear the audio. When I change the Input /Codec to "Hardware-accelerated decoding to VA-API Video Decoder" I get video playback again, but with the same behavior as previously described (freezes).

A quick list of what I've tried:

• Restarting the system
• Uninstalling / Re-installing Nvidia driver & VLC
• Installing / Switching to VLC version 3.0.18 (apt)
• Installing / Switching to VLC version 3.0.20 (flatpack)
• Installing / Switching to Nvidia Driver 535 (via "Software & Updates")
• Installing / Switching to Nvidia Driver 545 (via "Software & Updates")
• Installing nvidia-vaapi-driver (apt)

Relevant Software info:

• VLC Player v3.0.20 (installed via Flathub)

Relevant Hardware Info:

• Motherboard - ASRock X339M Taichi
• CPU - AMD Threadripper 2970WX
• GPU - Nvidia RTX 4070 Ti
• Memory - 128GB DDR4@3600Mhz
