Yes, there are some issues with the bobbing solution and the current implementation is a hack due to an nvcuvid.dll deficiency. When I update the dialog with the recent correspondence you will see what is going on in that regard. Engineer O has said that he will try to get it working properly. And given what he has done so far, I expect it to be resolved.
I'm working on MPEG integration and MKV container support right now. |

Intel Xeon X3360
nVidia GeForce 8600GTS 2GB RAM (who cares) Windows XP Professional SP3 I installed it (couldn't figure out the whole missing license thing), but I gladly paid since I've been using free stuff for years and its the least I could do. Got the license, I can demux files fine. **EDIT** I had to drop the nvcuvid.dll in the system32 dir to get it to work** Couple of Questions if I may: #1 - When I 'encode' , 'transcode' (whatever), my h264 content to, say xvid, in vdubmod ... I'm seeing same exact fps than what I normally see (with same CPU usage). so, "how" do I know if I'm using anything correctly or not? Or perhaps better stated ... I don't know what I'm doing. #2 - when one turns deinterlace=true after the .dga file in the AVCSource line in my .avs file; will that actually deinterlace the file, or do I still need a plugin to perform that action? #3 - when people are stating that they are getting 60fps at 0% CPU usage ... what are they referring to? Just the rendering of the AVC file itself? In other words, it has nothing to do with 'encoding/transcoding' (I don't know the correct vernacular). Thanks for answering, and thanks Donald for everything you do (rule violation??) |

ok, by adding:
AVCSource("1.dga", deinterlace=true) The output file (lagarith) was deinterlaced (what seems to be very well) [I'm working with a 1080i h264 source file] Is there something else I can add that will provide frame decimation so that I don't have to use 'any' plugins at all in my script for sources that require IVTC? If that were the case, I would be a happy guy here (less work for me in backing up my shows). Additionally, when dealing with 720p content, I have been reading this thread, and it seems that one can do this: a=AVCSource("file.dga",deinterlace=true,use_top_field=true) b=AVCSource("file.dga",deinterlace=true,use_top_field=false) Interleave(a,b) ??? To achieve 29.97fps (from 59.94)? Please be kind to me, I'm new at this stuff for the most part. |

Tell me more about your source material. Better yet, post an unprocessed source sample. Then I can advise you properly. |

Two files there. 1080i which requires deinterlace (of course) and decimation (since it should be 23.976fps). 720p which requires halving the framerate to bring it "back" to 29.97fps. Not sure if this is what you were asking for? Bottom line - I tried with deinterlace=true in the line with the 1080i (subsequently had to decimate in the script as well) and it turned out really well. I'm asking if one can add something (in addition to) that will allow for decimation as well as deinterlace (without having to use a filter in my script). I understand what you wrote above, so I guess that's not possible. But, what is needed in order to get the 59.94fps down to 29.97, other than separatefields()? Are there options? |

Sorry if this was asked before but I don't get the point of hardware decoding, isn't the decoder mostly used for transcoding and shouldn't rather the encoder use the hardware instead?

The point is in freeing up CPU for encoding by moving source decoding to GPU. As for encoding needing hardware, CUDA in its current state is no good for that (as per x264 dev experience, and DS actually saying he'd rather learn GPU assembly then use CUDA for encoding)

Another bug (affects both DGAVCDecNV and DGAVCDec):
When indexing the M2TS of Die Hard (over 2 hours long, nearly 30 GB big), an error message appears at frame 138187 (or at frame 162775 for DGAVCDec) that says: "Could not allocate memory: AllocPPS: slice_group_id" At this point, memory usage for DGAVCIndexNV.exe is at 137148 kilobytes. Maybe this is a limit? Trying to use the same instance of DGAVCIndexNV.exe again fails right at the start of the indexing with the same error message. I couldn't cut out a sample, because the error doesn't appear with small streams. |

1. Speedup of transcoding for some machines. 2. Correct decoding of streams that libavcodec still has problems with. 3. Access to the PureVideo deinterlacing and possibly the 3:2 engine to come. 4. Decoding of VC1 to come. 5. Integration of MPEG, AVC, and VC1 into one application. |

Sorry if this sounds completely pointless, but on the filter page on your site, do you periodically update the correspondance between you and NVIDIA?

Congrats on your new software, Donald. You seriously deserve some beer money for all your hard labour!
May I humbly suggest, that you put a slightly more informative text into your "Missing License" dialog; as usual I didn't RTFM, and I had no idea what to do. Maybe you could also allow it to decode the first 10% of a given clip, just as a teaser. MP4/MOV parsing would also be exceptionally useful, since MPEG4 seems to become a quite common container. CUDA development is very interesting - especially if they get their async interface working optimally. Keep up the great work!

I can use the "beer money" to buy the MP4 spec I need. I've just used some it at lunchtime to buy the BluRay Disk I need to test memory leak issue reported above.
You suggestion on the licensing is a good one. I will do something about that. |
