I think there is a problem with the PureVideo deinterlacer. Here are the scripts and the results:
1. Single rate deinterlacing: Code:
MPGSource("E:\Columbia\VTS_01_1.demuxed.dgm", deinterlace=1) crop( 10, 4, -10, -2) LanczosResize(640,528) trim(0,2500) 2. Double rate deinterlacing: Code:
MPGSource("E:\Columbia\VTS_01_1.demuxed.dgm", deinterlace=2) ChangeFPS(25, linear=true) crop( 10, 4, -10, -2) LanczosResize(640,528) trim(0,2500) The first video seems choppy to me and the second one smoother. Shouldn't those two videos look the same?

I use HDV cameras that output m2t files with mpg2 video and mpg1 audio.
When I open these files in the index program it comes up with an error about audio streams types not matching. Mentions ac3 and aac, which these files have neither of these types. This is preventing me from doing batch command line encodes and also this didn't happen with your non GPU version. I either need a way to specify the audio pid or disable error messages or both I guess. Or make it work like it did in the non accelerated version. Thanks Here is a link to sample file http://avs-scratch.s3.amazonaws.com/...ooper-mjmp.m2t |

Here's a sample of the audio delay issue I'm experiencing if I use VideoRedo to edit my files:
http://www.mediafire.com/?sharekey=4...4e75f6e8ebb871 It's very similar to the one xopowo discussed in the DGAVCDecNV thread. DGIndex= 32ms. DGMPGDecNV =-619 ms Thanks for wanting to fix the issue Neuron2. |

Works nicely. Using the PureVideo deinterlacer on 1080i TS -> 720p AVC encodes, I'm seeing 24% speed bump on first pass, and 12% on second pass. That's the fastest increase I've seen on anything, from swapping out any one piece in my encoding process. Thanks.
Question: How do I get audio to demux? The documentation makes it look like it's supported, but I'm assuming this just isn't implemented yet. I select Audio > Audio Demux. Set the one and only audio stream (which is already set anyway); close the window. Save the project. No audio demuxed. Last edited by UsedUser; 12th March 2009 at 07:45. |

I'm getting an error then a crash on drag & drop of multiple files in sequence. Something is not re-initialized between files.
Drag & drop a TS file into the app. Do something if you like, or don't do anything. Drag & drop another TS file into the app. Try to play or save the project. Try File > Close then drag & drop again. On Play: "No video frames found!" On Save: "Timed out looking for sequence header." Or sometimes the attached image then a crash. Couldn't reproduce the exact steps on the crash.

Is it a requirement that the screen saver and Windows account locking be disabled?
When I lock my Windows account (i.e., on screen saver start), the CUVID server fails. I get two pop ups: Server: cuvidMapVideoFrame() error. Server: cuvidDecodePicture() error. The cuvidDecodePicture() error repeats until I quit encoding and restart the CUVID server. |

As clearly described in the release notes, multiple file opening is not yet supported. I don't know anything about the screensaver issue. It may be an Nvidia driver strangeness that I have no control over. |

Ah, I see that now. I did read all the documentation. Don't know what I thought it meant at the time, but it didn't occur to me that it meant that. In a future release, you might consider clarifying what the statement means for the user: "The application must be closed and reopened between opening each new file." Thanks. |

Can I ask what was unusual about this case? I'm curious about the details. It was originally an ATSC broadcast transport stream, which I segmented with VideoReDo. Also wondering if I should contact my local broadcast affiliate or VideoReDo developers about something they could avoid doing. |

The stream is fine.
As I parse video transport packets during Save Project, I look for the first I frame right in the packet data so that I can start demuxing audio packets as soon as possible (I don't want to wait until the video decoder sees that it is an I frame because some audio packets could be skipped). But I was looking only in packets with payload_unit_start_indicator set. The problem was that the sequence header carried quant matrices and this pushed the I frame picture header into the next transport packet, which did not have payload_unit_start_indicator set. And so I never detected the I frames and audio demuxing never got started. Last edited by Guest; 13th March 2009 at 14:00. |

I just put the fixed version up for you:
http://neuron2.net/misc/DGMPGIndexNV.exe Let me know how it works for you. Still have to look at the drag-and-drop issue. |

neuron2,
I found a solution to the audio delay issue with VideoReDo. After reading some of the above posts I decided to look at VideoReDo's options. By default, VideoReDo is checked to convert all I frames to GOP. Once I saw that, I unchecked the box and now the audio delay issue is gone. Edit: Nevermind. I forgot I put your new exe inside the folder last night. The results were the same with I frames being converted to GOP. I didn't think you'd fixed the issue I was having with VideoReDo files, just UsedUsers. Anyway, the new .exe seems to have fixed my issue as well. I must have missed something in the above posts.
