I have no problems with movies (24p). Interlaced works fine and dandy if I set the setting in LAV CUVID to "Film mode". Set it to "Video mode" and it gets stuttery. Also, I just tried it with an episode of "Avatar: The Last Airbender" (the cartoon, not the crappy movie), which is 480i, and the results seem to be the same. |

Did you try first changing the refresh rate then commencing playback? There is certainly something Odd (have yet to get to the bottom of it) where using madVR's refresh rate changer I can not keep the final queue from dropping to Zero and hence then dropping frames in conjunction with LAVCUVID/nvidia.....

Getting Closer to smooth playback! - I found one issue in that J.Rivers MC's "Video Clock" (aka reclock) is causing most (not all) dropped frames when ON with this combo of filters when madVR changes the refresh rate - I've posted over there.

Okay so I'm not sure what the heck was going on, but the problem seems to be solved. I was trying some things and started getting some ODD operation from MPC-HC where it would always stay on top and full screen, preventing me from accessing menus (like the LAV CUVID setup menu) and causing other headaches like closing MPC-HC! I had to uninstall MPC-HC (deleting all settings), reinstall, and get everything set back up. Once I got everything set back up, I changed over to LAV splitter. Now I get smooth playback with deinterlacing set to "video mode". Yay. In short tests, it seems that I still get a hiccup here and there, so I might give Reclock a try later and see what happens, but the original problem I asked about seems to be solved. |

You can use the regular video decoder as well, and I believe it's basically the same. Just set it to accept raw formats, and disable decoding of whichever formats you don't want decoded.

hi i have been using this for some time now, working perfect so far (with mad vr)
but my question is about quality, which should give me the best quality? core avc, lav cuvid or mpchc dxva? or they are just the same?

MPC-HC DXVA = not so smooth. LAV CUVID = perfect if pair with ffdshow filters. CoreAVC = fine, but seeking problem and not so nice support Edit: For me, there's no difference when watching with smaller screens (22" - 32"), but with large screens (42" - above) I see some pixelation.

After some test with dvbviewer pro and LiveTV i recognized some problems with format changes and channel changes (mpeg2 and h.264).
On format (channel) changes the pictures freezes several seconds or stopped until I rebuild the graph. Dvbviewer does not rebuild the graph by format/channel changes. LAV CUVID doesnt like on the fly format changes? By the way LAV CUVID works very well here with correct deinterlacing (576i50 and 1080i). Thanks for your good work! GPU= GT430 Driver= 275.33 (win7 32bit, evr custom renderer) |

It constantly stuttering, pausing, freezing and shows a black screen and doesn't play smoothly. It uses quite a bit of the GPU, I'm getting around 57 to 71% while it's decoding but that drops to zero when it is failing to decode the stream. I believe it is meant to be the Video Engine that does decoding. That is what gets used when neuron's DGDecodeNV is decoding H.264 video. Comparing with CoreAVC using CUDA, the GPU load is much higher although the video engine load is a little lower than CoreAVC at around 25%. With Mpeg2 everything works fine. I'm using a 1GB GT 240 with the latest 275.33 drivers on Win XP SP3. Therefore, it seems that some more work is needed to get this working correctly. I look forward to trying it when it is working better. |

LAV CUVID Decoder 0.9
Code:
0.9 - 2011/07/05 - Slightly faster seeking - Improvements to dynamic format changes - Safe-Guards against crashes inside the NVIDIA decoding functions This is a pretty minor release, but i wanted to get those fixes out before they rot on my disc for much longer while i work on other things. So here it is! Have fun!
