I'm just assuming here you're using madVR 0.67 - which is actually causing this problem.
In any case, i've applied a small fix which should make LAV CUVID more resistant against this problem in the future.

Yes I was using madVR 0.67. I downgraded to madVR 0.66 and all is well. |

Aspect ratio bug
Looks identical like in CoreAVC - http://forum.doom9.org/showthread.ph...00#post1390600 |

Disable "Use Stream AR" in LAV CUVID settings. Those encodes are just broken, having a wrong AR encoded in the bitstream. Haali manually overwrites that AR, so CoreAVC didn't have to offer this option in the decoder.

quick question guys if anyone knows the answer it would be great. Does the output colorspaces option in lavcuvid have an impact when lavcuvid does hardware de-interlacing?
I'm outputting from lavcuvid into avisynth, which doesn't take nv12 as input, but I'm afraid that selecting yv12 in lavcuvid will have a negative impact on my de-interlacing quality but am not sure if this is just the final output colorspace, or a colorspace used internally for deinterlacing.. Edit:btw this is using nvidia gpu which obviously has better deinterlacing when fed nv12 afaik Last edited by mark0077; 29th July 2011 at 01:06. |

I think the quality will not be affected if you change from nv12 to yv12 but I'm not 100% sure

The decoder internally always works with NV12, its the only format it natively supports at this point. If you request YV12 output, it'll be converted manually (eg. by LAV CUVID, not by the NVIDIA driver) afterwards.
There is no quality difference between NV12 or YV12 output - both formats are 100% identical (except their different memory layout, of course)

I thank for your decoder codec.
But I have one problem for divx/xvid format on my laptop with Nvidia optimus system. My GT540m is VP, C feature. 0.7 version can decode for divx/xvid with Nvidia optimus system. But 0.8 and 0.9 version can't decode that. I think that you don't consider Nvidia optimus system. |

XVID/DIVX is really not the most complicated format, and i don't think it hurts anyone if its falsely detected as not supported.

Nev,
I've gone back to LAVcuvid for 1080i since there are no other options out there that can match the deinterlacing quality. While not perfect, it's still better than anything I could do with FFDSHOW + YADIF. I've done much reading here: http://www.avsforum.com/avs-vb/showthread.php?t=1157287 Also, those videos provided there might prove useful to anyone that wants to check the deinterlacing capability of their setup. And of Nev to fine-tune LAVcuvid. Quote:

The Cheese Slices video is a common testing video, already knew it.
Also, i don't think speaking of "percect" when talking about deinterlacing is really realistic. You have a video with only half the information, and you have to interpolate the missing information. There is clearly still some artifacting going on with the hardware deinterlaces - however this is a very artificial sample, on real world samples, i consider the GPUs already pretty damn good.

nev,
today I tried an old MPEG2 .ts TV stream and it didn't play correctly with LAV CUVID while LAV Video, FFDShow and madVR's Decoders played it fine. From madVR's OSD I noticed that it was a 4:2:2 so I guess that my (if any) video card doesn't support it in hardware. Is this correct? Is there anything I can do to have LAV CUVID as my preferred decoder but still use another one for such unsupported streams? If you need I can provide a sample, but I think you already have such streams.

All hardware decoders are currently limited to 4:2:0.
I already have the code to probe the MPEG-2 media type if its 4:2:2 or 4:2:0, and refuse connection in this case. I just need to get around to adding it.

Yep Finally Lav Cuvid would be able then to fallback to any preferred Software Studio Profile Decoder as Lav Video, MPCs Video Decoder, Mainconcept, Nero ect the same then needs to be done for H.264 and those different non "consumer" hardware decoder supported profiles.

Hi - hope someone can help...
Can anybody explain the following:- I'm testing with a 1080i retail music video BD, output to my LCD monitor via DVI, 1920x1200@60Hz NVIDIA GeForce 9500GT CUVID Settings:- Frame Rate - 50p/60p (Video) Use Stream Aspect Ratio (yes) Use HQ DXVA processing (yes) Field Order (Auto) Output Format (Auto) If I set Deinterlacing to "Adaptive", the video seems to play back half-speed compared to the audio and falls horribly out of sync. The renderer properties (EVR) are showing 59+ fps... However if I choose either of the other None/Bob settings, EVR shows same fps but Video plays at correct speed... Thanks in advance if anyone can explain this! m |
