Trying to deinterlace with Bob NVEnc; job crashes

[Selur]

I just noticed your PM. First bug I see is that it forces you to drop one field.

That's how the deinterlacer works.
Either:
a. you use 'bob' and one frame per frame is returned
or
b. you use 'adaptive' and then by default, if the frame is marked as interlaced in the input, the first-field get's dropped or by setting '-drop_second_field' you drop the second field. If the field is marked progressive in the input it not deinterlaced.

XXXX_cuvid AVOptions:
  -deint             <int>        .D.V....... Set deinterlacing mode (from 0 to 2) (default weave)
     weave           0            .D.V....... Weave deinterlacing (do nothing)
     bob             1            .D.V....... Bob deinterlacing
     adaptive        2            .D.V....... Adaptive deinterlacing
  -gpu               <string>     .D.V....... GPU to be used for decoding
  -surfaces          <int>        .D.V....... Maximum surfaces to be used for decoding (from 0 to INT_MAX) (default 25)
  -drop_second_field <boolean>    .D.V....... Drop second field when deinterlacing (default false)
  -crop              <string>     .D.V....... Crop (top)x(bottom)x(left)x(right)
  -resize            <string>     .D.V....... Resize (width)x(height)

see: "ffmpeg -h decoder=XXXX_cuvid"
Only thing that Hybrid does not support is 'weave', since it does not seem logical to use 'deint' and then not deinterlace.
