Also, what tracker? LAV CUVID doesn't have a public bug tracker.

Anyway ... just swapped out my last ATI card for a nvidia one. FYI - you are not the only one getting better results from nvidia over ATI. Cyberlinks PD9 can output AVC 50 or 60p using the nvidia GPU but not with ATI. |

But as nev allready mentioned this sample is strange and for such a thing you would need something very adaptive to get it right Though that it works in a full Software chain (Lav Splitter->Lav Video->EVR) seems to show @ least that Intels Telecine does it's job nicely and Nvidia should not fail here either on EVR with the same Software Decoding setup.

But it is a damaged cut and all my experience say "interlaced short mpeg2 cuts are always problemetic unless they are cut by Video ReDo or VideoReDo TV Suite." So this sample may never be a trial subject imo. EDIT: I haven't used Cuttermaran for years, this might be another working way to cut the mpeg2 files correctly.

If it is addressed to me, i just said your sample has been cut with a non-suitable SW (IMO) so it has lots of issues. This is not your fault.
Sorry maybe i posted in wrong thread? Last edited by rica; 6th September 2011 at 21:55. |

In any case, I will wait for the Blue Ray release of Game of Thrones (December) before I do anything.

Also did you tested on EVR with Nvidias Telecine in the controll panel active or disabled ? (Though Lav Cuvid should overwrite this i guess) Xaurus: You should also contact the ISV that Software you used to cut this and make him aware of this discussion

Hi Crunch.
I can not see any difference between MAdVR and EVR. Inverse telecine is enabled or disabled has no effect on the result. EVR custom (even it shows 23.97 fps) fails; it has lots of dropped frames. But as i told before this cut can not be reference. Take care. |

I've encountered a problem with a MBAFF 25p (flagged as i) AVC Blu-ray file and think I've diagnosed the troubles. The symptoms are video stuttering and are most prominent with madvr, but you can also see them with EVR. The trouble seems to be with the deinterlacing of the progressive material to 50fps even though the stream header says 25fps. If I turn the deinterlacing off or change the deinterlace framerate to 50p/60p then the stuttering disappears.

Hi nevcairel
I'm a big fan of your projects, and I really love the quality, but I seem to have a performance bottleneck in my system and I was wondering how I might get to the bottom of it. Decoding MPEG2 1080i streams, in PotPlayer with either EVR, EVR CP or madVR renderers, my system seems at best to drop approx 1 frame per second. System is an i7/965 at stock clocks with a GTX260 card. Its running Vista 64bit at the moment and is in a dual-head configuration. I'm planning on a fresh format to Win7 anyway but I'm wondering if my GPU is bottlenecking, and if this is the case whether upgrading to a DDR5 model might help, over the DDR3 RAM in the 260? |

The easiest way to check if there is some obvious performance bottleneck would be to get GPU-Z and check the video engine load, GPU load and memory controller load - as well as GPU memory used.

I compare CoreAVC 3.0 to LAV CUVID 0.12, the result is this.
LAV CUVID 0.12 VPU Load = 33% GPU Load = 12% Memory Load = 721MB/1024MB CPU Load = Average 14% CoreAVC 3.0 VPU Load = 32% GPU Load = 11% Memory Load = 738MB/1024MB CPU Load = Average 20% *LAV Video 0.35 VPU Load = 0% GPU Load = 38% Memory Load = 332MB/1024MB CPU Load = 30% I used GPU Observer Gadget (I think it's the same as GPU-Z) to measure the loads. Filters used : LAV Filters 0.35, Reclock, madVR 0.74, MPC-HC. I don't know who is the real winner here but my observation is, faster seeking with LAV CUVID. Is LAV Video a software decoder like ffdshow? Additionally, I got no glitches in madvr using LAV Video wherein CoreAVC and LAV CUVID I get 5-8 glitches, I'm using the default settings of madvr.

I'm focusing on other projects at this time. I'm not aware of any issues that need immediate attention, everything is working pretty good.

I want to say, very GOOD job you have done on this codec, is allot beter than coreavc that dont even work anymore after 2.6 under dvbviewer.
Also channel change is allot faster than any codec i have seen, so keep up the good work. |

Showing only 280mb used of 896mb, 16% GPU load, 6% Memory Controller Load, 6% Video Engine load, less than 5% CPU usage but I am still losing approx 1 frame every .5-1 second... Testing again it seems to be more related to madVR than LAV CUVID. I think with EVR CP it drops almost no frames. However if I have any significant CPU utilisation (say video encoding), it will drop more. Do you have any idea whether being in dual head mode might have an impact? |
