I just checked your clip and, yes, I do see what you see.
LAV CUVID + HW interlacing : plays smooth
LAV (WMO) + Madvr (deinterlacing) : smooth
LAV (WMO) + yadif :
the first half of the clip, I see no dropped frames.
However, I see the decoder queue going down. Normally it stays at 15-16 (complete filled).
The second half of the clip, I notice a very low decoder queue (6 and lower) and at 80% of the clip, it starts dropping frames.
My first thought was it 's because both the WMO decoder and LAV-yadif are not multi-threaded.
Without yadif, the WMO decoder tops on 105 fps on my system, so that would mean that yadif is taken *a lot* resources.
The ffdshow implementation of Yadif is however MT IIRC, that's probably the reason why it runs smoother with the DMO decoder.
To make it simple for now, just disable yadif and let Madvr or EVR do the de-interlacing : it's faster and will give a superior result compared to yadif.
Nev : is making yadif multi-threaded still on your to do list ?
