that's why i said a direct implementation would rock (that wouldn't be DXVA) it would give GPU supported editing possibilities via Dshow
you can't get the frames via DXVA only direct via Ncuvid

@leeperry
the era of "GPU acceleration" is over we are in the era of complete Bitstream Video Decoding on consumer PC systems now, as long as you only work via Ncuvid there is practically 0 cpu utilization

well that would finally be true "no b/s" GPU decoding
no more NV12 only/VMR9 only/"no ffdshow PP for you coz you've been a naughty boy" plus CoreAVC would be pointless, as most ppl who are using it at this point don't wanna go DXVA because it's L4.1/NV12 only I'd be happy to register for it, and many ppl too(especially on AVS/HCFR) |

Hi, I got a problem with DGAVCDecNV.
Actually I wanted to compare the decoding quality of DGAVCDecNV to DGAVCDec. Thereby I stunbled onto something I didn't expect. With AvsP I just loaded the appropiate .dll and used AVCsource(). from "Die Welle" Blu-ray DGAVCDec .............. DGAVCDecNV .............. DGAVCDecNV "reverted" from "Hellboy" Blu-ray DGAVCDec .............. DGAVCDecNV .............. DGAVCDecNV "reverted" DGAVCDec seems to be correct, the actual picture of the frame decoded with DGAVCDecNV is slighty offset and stretched. I had the impression as if it was decoded to 1920x1088 and then cut at the bottom to 1920x1080. To "revert" that I added 8 lines at the bottom of the frame (->1920x1088) and resized it back to 1920x1080 et voilą the result was the same as the frame DGAVCDec decoded. Setup: DGAVCDec 1.0.6, DGAVCDecNV 1.0.6, Windows Server 2008 x64, 8800GTS512 180.48whql driver. It's the same with DGAVCIndexNV, also 1.0.8 and DGVC1Dec/IndexNV. I know of another user (Vista x64, 8800GT 512MB, 177.35) with the same problem. Prolly a Nvidia bug? if needed: "Die Welle" 20MB .m2ts sample created with DGSplit. (P4$5VV0RD: --- ) Last edited by vucloutr; 5th December 2008 at 20:28. |

I was going to buy this to support the author (even though most of the stuff I encode is MPEG2 1080i -> H.264 720p), but the lack of a demo and this glitch has me worried that for the occasional encode where I do want to use it, that I won't be able to. Can anyone else verify that this bug exists? |

I read through close to 40 pages of this thread and hadn't seen anyone else complain of that issue. I was wondering if it was something that only affected a few people. |

No, I have not duplicated it. I am still investigating.
Initially, I opened the sample in DGAVCIndex and DGAVCIndexNV and did Save BMP. The two BMPs were binary exactly the same. Now I am checking the DGAVCDecode(NV) output... |

Test 1: Open your sample stream in DGAVCIndex and then do Save BMP. Repeat with DGAVCIndexNV. The resulting BMPs are bitwise identical. Test 2: Serve the video via basic script using DGAVCDecode.dll to VirtualDub. Copy frame to clipboard and then save it using Paint. Repeat for DGAVCDecodeNV.dll. The resulting BMPs are bitwise identical. Earlier versions of DGAVCDecNV did not handle cropping rectangles properly. Please retest with the version given above. Also, be sure to update the CUVID server and nvcuvid.dll with the ones in the zip file. Last edited by Guest; 6th December 2008 at 00:49. |

strange though.
here with DGAVCIndex 1.0.7 + DGAVCIndexNV 1.0.8 http://www.imagebam.com/image/a3983b20099687 |

I have noticed a discrepancy in the description of the detected audio streams from the audio demux and the audio section of the information panel.
The source file is "Hellboy 2" Blu-ray m2ts. Notice in the audio demux listbox stream 1100 is labeled as "L+R" and in the audio section of the information panel it is labeled as "C+L+R+SL+SR 48 1536" BTW, is it possible to give these appropriate names, i.e. DTS Master Audio, TrueHD?

Well, I just redownloaded dgavcdecnv108.zip and suddenly, magically everything is fine. (i've almost gone nuts at this point..)
So I just looked up the two different "dgavcdecnv108.zip" files. You updated the nvcuvid.dll right? I had downloaded dgavcdecnv108.zip before you reuploaded it with the updated nvcuvid.dll. Seemingly the bug was in the old nvcuvid.dll: DGAVCIndexNV 1.0.8 to the left with new nvcuvid.dll, to the right with old nvcuvid.dll dunno what to say finally.. hm.. problem solved, thanks anyway.
