| Using VirtualDub 1.7.7 I have a file that the VirtualDub can not determine what the file type is. I used GSpot an found it was a Video codec: mp4v Name : MPEG-4 video Staus:Codec Status Undetermined Audio codec: mp4a: MPEG-4 AAC LC Info: 44100Hz , stereo (2/0) Can VitualDub work with these type of files? If so what am I missing? Or is the file some how corrupt? The file plays ok using Classic Media Player. |

Can open this file used http://www.tateu.net/software/. (Required installed QuickTime or QuickTime Alternative.)
Not related. Media Player Classic use DirectShow filters - VirtualDub not (except - http://forums.virtualdub.org/index.php?act=ST&f=7&t=15093). BTW Whay not use latest VirtualDub version? |

| Ok, I got the latest version of VirtualDub and the suggested plugin and placed them in the plugin32 folder. This time it is telling me that the file is unknown or unsupported file type. Any other suggestions? Thanks for the reply. |

| Which plugin? If DirectShow input plugin... ...when open, select video file and change file type to DirectShow input driver. If QuickTime input plugin... ...Quicktime.vdplugin file is in plugins32 subfolder? BTW VirtualDub Plugin Pack - input plugins with installer. |

I do not understand what you mean by the DirectShow pluging? I can not get VirtualDub to even open the the video. Here is what I am doing. Start VirtualDub. Select Open file Select video Hit ok This is when the error about Unkown or Unsupported file popup's up. So you see I can not even open or loaded the video. Yes, the QuickTime plugin is in the plugin32 folder and the inf file is in the main VirtualDub folder. About the DShowInputDriver.vdplugin , I have tried it both the plugin32 and plugin folder both yielded the same results, the unknown file or unsupported file type. One point here is I have nor run the other program auxsetup.exe . Do I need to run this program? |

Watch this video: http://ifile.it/7dewuo5
Not related. It's for VirdualDub frameserving. BTW Unfortunately, when i try... MOV or MP4 with MP4V > Gabest MP4 Splitter + ffdshow > DirectShow input driver = "File ... does not have a video stream." Also of course, can use Avisynth script (DirectShowSource or QTSource). |

| Ok , I followed you instruction and the file was open, using the direct plug-in. Thanks In the past when I used the program I never had problem opening a video. I tried using the Video: Direct copy But it said "The source use a algorithm that is not compatible with AVI files. Direct stream copy can not be use" Is there a way that I can keep from re compressing the video and losing more quality. Thanks for you patience with me. |

| Direct stream copy audio/video from MOV/MP4 to AVI in VirtualDub? At this moment - can't. Try MPEG Streamclip (it use QT) or Avidemux. (Save to MOV or MP4 container. To AVI - possible, but only for some A/V.) |

Does it still apply to the latest version ? I tried to open a .mp4 file and the following error message was displayed :
According to VLC media player the video track is "H.264 / MPEG-4 Part 10, AVC (Advanced Video Coding)" encoded. Installing ffdshow tryouts Beta 7 didn't solve the problem. I just would like to extract a sequence from the video. |

Yes - Direct Stream Copy mode was planned in QuickTime import plugin, but it seems that plugin is no longer being developed (last version from october 2007). However, You can change container to MKV (using MKVtoolnix) and then can try fccHandler's Matroska plugin (where Direct Stream Copy is possible).
Using QuickTime plugin (with installed QuickTime) or DirectShow plugin (with installed required DirectShow filters - splitter and decoders)? |

Thanks ! I used http://www.bunkus.org/videotools/mkvtoolnix/ to convert my .mp4 file to a Matroska one. Then I was able to open it and save the part I was interesting in. However I had to disable the audio because the track is "MPEG AAC Audio (mp4a)" encoded and apparently ffdshow tryouts doesn't properly support it. Maybe I needed a special plugin or something. But it doesn't matter as I was interested by the video in priority. Note that I found the http://forum.videohelp.com/threads/286901-VirtualDub-Now-Has-a-Directshow-Driver-Plugin thread (VideoHelp.com Forum) very useful during my search. It convinced me to install http://haali.su/mkv/ and ffdshow from http://www.x264.nl, because of the splitter & decoders you mentioned, but apparently I didn't have to. To sum things all I needed was MKVToolnix, the Matroska plugin and ffdshow tryouts. |

Do you have the version 2.3 of the Matroska input plugin? (if not, update it) ffdshow tryouts support it. If the audio doesn't work, try this: Go on File => Open video file... => Select the video => Check "Ask for extended options after this dialog" => Click "Open" => Check "Direct Stream Copy raw AAC (no ADTS headers)" => OK |

| Or... Save video and audio separately - video without audio track and audio through export to 'raw audio' - and mux A/V using AVI-Mux GUI (AVI or MKV) or MKVtoolnix (MKV). Also of course can de-mux audio to raw/binary and mux again with video using AVI-Mux GUI. Works for me - after that audio is playable. BTW I checked several files and indeed I noticed a same issue - when edit (and saving in Direct stream copy mode) some MKV files created previously from MP4 (re-muxed MP4>MKV). |

| @Placio74: Have you tried my method? |
| Posted by: Placio74 Feb 22 2011, 06:13 AM | ||
Of course, but I would point that issue affects only certain specific files. 'll check again later (afternoon)... @dub&duber, You can provide this MP4 file? Or reply whether Direct Stream Copy raw AAC (no ADTS headers) is sufficient for your video file... |

@Placio74: I have asked only because if there is a bug is better to report it rather than just workaround it.  |
| Posted by: Placio74 Feb 22 2011, 09:15 PM |
| You're right and... ... I had not noticed that I was a bit older version of VirtualDub. So, what I wrote earlier concerns VirtualDub 1.9.10. When I used VirtualDub 1.9.11 with same video file, issue did not occur. |
