09:07funderscore: another false positive
13:38gesh: Hi, I'm getting interlacing artifacts when trying to use the vaapi hwaccel under mpv (on a NV137). with accel: https://0x0.st/KOc2.png without accel: https://0x0.st/KOcL.png
13:40gesh: (the binary drivers are crashing my system and prevent me from confidently hibernating. I'm hoping the nouveau driver manages to avoid this)
13:47gesh: these issues occur for both h264 and vp8 videos
13:48gesh: and there is no acceleration for mpeg4
14:01gesh: I'm rebooting after clearing all remaining nvidia cruft
14:01gesh: brb
14:26gesh: nope -- even with all things nvidia upstream removed and the system rebooted, I'm still seeing the decoding artifacts, and the card isn't showing up in nvtop
14:29karolherbst: gesh: it's a bit weird, because we don't support VAAPI on those GPUs afaik. What's vainfo showing?
14:30gesh: only the integrated intel driver https://0x0.st/KOT5.txt
14:30karolherbst: yeah, so it's using VAAPI with the iGPU, which is fine. Maybe something in the displaying path gets wrong? Do you know if mvp renders with the nvidia GPU or the iGPU?
14:32gesh: not sure...
14:36gesh: vainfo suggests I only have the iGPU available
14:36gesh: despite nouveau being loaded
14:36karolherbst: yeah, but nouveau doesn't support VAAPI on your GPU
14:37gesh: ah
14:37gesh: where should it be showing up?
14:37gesh: vulkaninfo shows it: https://0x0.st/KOAN.txt
14:37gesh: but nvtop doesn't
14:40gesh: hrm. does nouveau not expose the gpu for use by nvml?
14:40gesh: because that might explain why nvtop doesn't see it
14:41chikuwad[d]: correct
14:44gesh: ok. still not managing to get anything to render with the gpu itself
14:44gesh: tried ffplay -hwaccel -i $vid and that doesn't render anything useful
14:46gesh: ah, ok, if I pass -hwaccel vulkan I see it complains Device does not support the VK_KHR_video_decode_queue extension!
14:50gesh: giving up, I'm out of time to try to fix this
14:50gesh: thanks for the help
15:08karolherbst: video acceleration is still work in progress and might take a while until it all lands and is supported
