======================
Good points.
My original ProRes422 HQ source input file before encoding to HEVC using
CinelerraGG/FFmpeg, was a in a valid HD 1920x1080i25 format.
I also had a look at the available ffmpeg pixel formats:
ffmpeg -hide_banner -h encoder=hevc | grep yuv422p10
Supported pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p
yuvj444p gbrp yuv420p10le yuv422p10le yuv444p10le gbrp10le yuv420p12le
yuv422p12le yuv444p12le gbrp12le gray gray10le gray12le
ffmpeg -hide_banner -h full codecs=hevc | grep yuv422p10
yuv422p10 64 ..FV.......
yuv422p10 3 ..FV.......
So now in a third attempt, I've tried to simply deinterlace the H.265
file, but still get the ffmpeg Vulkan hwaccel initialisation error.
I'm wondering if my deinterlace code line is correct, because the
deinterlaced output is smaller (halph the size) of the input file.
I would have expected it larger(?)
