This TS file can't be decoded with VT on macOS

[oviano]

I would have logged this as a bug on your system but the login page isn't responding for me.

This TS file was produced by FFmpeg, and encoded using NVENC HEVC with yadif_cufa used to deinterlace the source file which was a directshow capture in ASF format.

https://www.dropbox.com/s/yekpa39j0vpxb01/test.ts?dl=0

When this is loaded by VLC 3.0.4 it initially tries to use VT but this then gives an error and it falls back to wanting YUV 444, which itself seems a bit weird as the file is in yuv420p, although it plays ok.

Here is the VLC messages:

Strangely, when the file is produced in the same way except CPU yadif is used for the deinterlacing, the issue does not occur. It might not be the deinterlacing specifically, but the fact that one encode is done with the FFmpeg pixel format CUDA and the other with NV12. ffprobe reports both as yuv420 however.

It seems that VT doesn't have this issue on iOS/tvOS.

I would have logged this as a bug on your system but the login page isn't responding for me.

I get that you may have issues with the ticketing system, but this is not the place for bug reports.

Ok I saw lots of other bug reports in this forum but nevermind I’ve now managed to log a bug report, so feel free to delete this thread.
