Test conversion of a video file from DV p.5 to DV p.8.1. Script version 3.0, mode 8.1. An error occurs in the vpy script when using the libplacebo library.

do you have a sample? It's working fine on my end but I know that some iTunes P5 web-dl are not working.

PS, you must have a GPU that supports Vulkan to use libplacebo.

I also tested a few more samples with this profile, and the result is the same everywhere.

Intel UHD Graphics 730 supports vulkan, I also specifically checked the functionality of vulkan via ffmpeg - video decoding works, I think other filters will work too.

No issue converting this P5 video to P8 HDR10 on my end(i9 + rtx3070) but I also tried it on my cheap laptop with intel graphics and it failed, so libplacebo might not be supported at all on i-gpu.

Here, I converted it for you: https://drive.google.com/file/d/1ji9nRJbRL1UryoQ1ioilaTdveg-trDfp/view?usp=sharing
