Thx for comment,
cuvid can't output 50fps deinterlaced output, both frames are same, and
default behavior for yadif is to downcovert to half frame rate, so i
think is very clever to do the same here.
Also if we return in decoder that input is framerate/2 when
deinterlacing we should stay with that!
if (ctx->deint_mode != cudaVideoDeinterlaceMode_Weave)
avctx->framerate = av_mul_q(avctx->framerate, (AVRational){2, 1});

It does make sense, the deinterlacers convert 50 interlaced fields to 50
progressive frames, like for example yadif can do as well.
And disabling that functionality by default seems strange to me, as it's
clearly the superior mode of operation.

There is no need to copy second field if deinterlacing, it doesn't make
sense to use two times same image.
