[lavilao]

Important Information

Provide following Information:

• mpv version : lastest mpv & libplacebo from master
• Linux Distribution and Version: manjaro gnome
• Source of the mpv binary: self compiled
• If known which version of mpv introduced the problem
• Window Manager and version
• GPU driver and version: Mesa 21.2.5
• Possible screenshot or video of visual glitches

If you're not using git master or the latest release, update. Releases are listed here: https://github.com/mpv-player/mpv/releases

Reproduction steps

with lastest mpv & libplacebo from master gpu-next is not working with ewa_lanczos, with gpu-api=opengl it throws this error [vo/gpu-next] Tried calling `pl_swapchain_resize` with unknown size! This is forbidden for OpenGL. The first call to `pl_swapchain_resize` must include the width and height of the swapchain, because there's no way to figure this out from within the API. and then crashes with i965: Failed to submit batchbuffer: Input/output errorche: 960s/139MB or stays on a black screen with audio still playing, with gpu-api=vulkan [vo/gpu-next/vulkan/libplacebo] vk->QueueSubmit(cmd->queue, 1, &sinfo, cmd->fence): VK_ERROR_DEVICE_LOST (../src/vulkan/command.c:481) [vo/gpu-next/vulkan/libplacebo] Failed holding swapchain image for presentation [vo/gpu-next] Failed presenting frame! and after that is a black screen, lanczos and spline36 works ok

Expected behavior

mpv runs fine with polar (ewa_lanczos) scaler

Actual behavior

crashes or black screen and the gpu hangs (desktop freeze for a couple of seconds)

Is this still an issue? I'm assuming it's caused by upstream (due to the GPU errors being logged) either way, but I might as well ask.

[Dudemanguy]

Going to assume this is solved (i.e. works on my machine).

[lavilao]

Scale=ewa_lanczos does work, the issue seems to be cscale=ewa_lanczos (at that time they were the same) whenever I use cscale=ewa_lanczos the vídeo just loops in the 1st second or goes directly black.

[Dudemanguy]

Could you post some new logs?

[lavilao]

mpv -no-config -vo=gpu-next -v -v -gpu-api=vulkan -cscale=ewa_lanczos -log-file=mpv-logs.txt mpv-logs.txt

[haasn]

I don't see anything wrong or suspicious in that log

if it helps here is a picture, the audio kept going but the video was on a loop and when hover over the bottom the interface broke
