vapoursynth.Error: StackHorizontal - kingcrimsonster - 28.09.2024

When I try enable resize the input file 720:480 to 820:548 and prees preview button - appears error:

Original should be YUV420P8 which got resized to width=820, height=548
original = core.resize.Bicubic(clip=original, width=820, height=548)
Filtered clip was YUV420P8 which got converted to RGBS for RealESRGAN,
clip = core.resize.Bicubic(clip=clip, format=vs.RGBS, matrix_in_s="470bg", range_s="limited")
then downscaled to 820x548
clip = core.fmtc.resample(clip=clip, w=820, h=548, kernel="spline64", interlaced=False, interlacedd=False)
and converted to YUV420P:
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P8, matrix_s="470bg", range_s="limited", dither_type="error_diffusion")
at:
stacked = core.std.StackHorizontal([original,clip])
both clips should be YUV420P and 820x548, Vapoursyth complains about:
S t a c k H o r i z o n t a l :   c l i p   f o r m a t   a n d   h e i g h t   m u s t   m a t c h

From what I see, everything Hybrid does is correct.
My guess atm. is that the AviSource source filter does not output YUV420P8, but something other.
Would need a small sample of the source, which also causes the problem to look into it.
Does it also happen when not using AviSource?

Quote:Does it also happen when not using AviSource?

It's the same in both options.

RE: vapoursynth.Error: StackHorizontal - Selur - 28.09.2024

I can reproduce the problem, looking into it.

RE: vapoursynth.Error: StackHorizontal - Selur - 28.09.2024

AviSource, outputs: YUV422P8 and since Hybrid detects that the vfw decoder is available it uses for UT-Video AviSource.

So to be clear, this is not a bug in Hybrid, but either a bug in:
  • MediaInfo for reporting the wrong color sampling, or
  • UT Video for not signaling the correct color sampling, or
  • the vfw decoder returning the wrong color sampling.
Argh.
As a workaround, I added a new option: 'Never use AviSource'.

Enabling it will cause Hybrid to not use AviSource and using BestSource or LWLibAVSource works fine here.
(In general, I would not recommend enabling this, but it should help with your problem.)

=> uploaded a new dev with the new option.

Thank you, now working!
