Hi guys!

I didn't want to start a flame, just understand and learn a little bit more from who knows really more than I do!

That's my situation now: after checking every option in LAV, the output is NV12 for SD and HD 8 Bit (MPeg2 DVDs, and H264 .mkv) and P010 for HEVC 10 Bit UHD; with the same settings of before, madVR produces dropped frames: I suppose because colorspace conversion and chroma upsampling are on his shoulder, and I have to re-optimize.

If I simply enable SVP to do frame rate conversion for SD and HD, LAV changes automatically his output to YV12: I suppose to "talk" with FFDshow input, am I right?

In this situation, FFDShow output at NV12: wouldn't be better to force his output at YV12 (to avoid the YV12 - > NV12 conversion), and let madVR do directly the YV12 - > RGB conversion?
