Comment (by triffid_hunter):

 I ran into this today via mpv on Linux.

 Using ffmpeg-6.1.1-r5 Gentoo package, nVidia proprietary driver 550.90.07
 on an RTX3070.

 $ mpv --gpu-api=vulkan --hwdec=vulkan file.mp4
 …
 [vo/gpu-next/libplacebo] Available surface configurations:
 [vo/gpu-next/libplacebo]     0: VK_FORMAT_B8G8R8A8_UNORM
 VK_COLOR_SPACE_SRGB_NONLINEAR_KHR
 [vo/gpu-next/libplacebo]     1: VK_FORMAT_B8G8R8A8_SRGB
 VK_COLOR_SPACE_SRGB_NONLINEAR_KHR
 [vo/gpu-next/libplacebo] Picked surface configuration 0:
 VK_FORMAT_B8G8R8A8_UNORM + VK_COLOR_SPACE_SRGB_NONLINEAR_KHR
 [vo/gpu-next] Assuming 59.950550 FPS for display sync.
 [vo/gpu-next] Loading hwdec drivers for format: 'vulkan'
 [vo/gpu-next] Loading hwdec driver 'vulkan'

 The patch kindly offered by Sn0wCrack does seem to prevent the crash from
 occurring with a quick test.
