[BUG] Incorrect range signalling

[Selur]

Deinterlacing SD content, I get a constant ~660-667fps/s with 60% CPU and 70-80% GPU. (No speed drop on 2 1/2 hour source.)

clip = qtgmc.QTGMC(Input=clip, Preset="Fast", TFF=True, opencl=True) # new fps: 50

with OpenCL and Neo enabled.

DFTTest2 should be available when an NVIDIA card is detected, which should be the case. (for SD content, using DFTTest2 is a bit slower for me, speed is ~656-660fps)

During my tests, the source was located on a normal hdd and the temp folder lied on a m2s drive and I used NVEncC as encoder.


Using software encoding and:

• Bestsource in cpu mode I only get ~140fps. (speed starts at 400 and quickly goes down)
  
• Bestsource in cuda mode I get ~585fps. (speed starts slow and increases)
  
• LWLibavSource in cpu mode I get ~580fps. (speed quickly hits 580fps)
  
• LWLibavSource in gpu mode I get ~580fps. (speed quickly hits 580fps)
  
• FFMpegSource2 I get ~590fps (speed quickly hits 590fps)
  

so on my setup the decoder doesn't matter much.

While using software decoding with LWLibavSource and encoding, I get 73%CPU usage (no GPU usage) and ~580fps.

Speed does start up at 600fps, but the quickly settles around 580fps.

The only setup could see a slowdown was when using Bestsource in cpu mode, but even then the speed dropped quickly (after a few seconds).

=> I suspect anti virus or similar interfering on your system, did you check your taskmgr what else was running in the background?
