I am unable to open .mov files from my Contour helmet camera and .mp4 files from my GoPro helmet camera in 32-bit Virtualdub. In both cases, get a black screen with the error message "missing codec AVC1" What do I need to install? I have
QuickTime Pro 7.73 installed,
QuickTime.ini in my VirtualDub root folder,
the QuickTime and AC3 plugins in the plugins32 folder
the AAC ACM and AC-3 ACM codecs installed in Windows (I've installed both the 32 and 64-bit versions of these -- is that a problem?)
ffdshow installed -- but how to configure? |

When you did install ffdshow, you should normally find three different items via the Windows Start menu:
- Video decoder configuration
- Audio decoder configuration
- VFW configuration
Via 'All programs' you should find these items in the "FFD_Show" entry
When using the QuickTime inputdriver plugin for VirtualDub, then 'Video for Windows (VFW)' codecs will be used (and audio ACM codecs).
You can 'enable' the needed ones via starting the VFW configuration, and via the 'Decoder'-tab click on 'Codecs' in the left column.
Then you can click at the right, at the first line H264/AVC, on the word 'Disabled' and change it to 'libavcodec'. Click OK.
Now, try again via VirtualDub to open your MOV-files via the QuickTime plugin...
N.B.: if you should install the DirectShow inputdriver plugin for VirtualDub, than you should also use DirectShow codecs (available via ffdshow).
In that case, you can enable the ffdshow codecs via Video- and Audio- decoder configuration.
When you start VirtualDub 32-bit, it will use 32-bit filters, inputdrivers and codecs.
In the same manner VirtualDub 64-bit will use 64-bit filters, inputdrivers and codecs.
Normally it should be no problem to install them both... (when you have a 64-bit Windows operating system). |

Is there any way to fix the "missing codec AVC1" problem without installing ffdshow? I am using VirtualDub on my computer at work and don't have Admin rights to install the program. |

You could ignore ffdshow and use another filter such as http://code.google.com/p/ffinputdriver/downloads/list unpack to virtualdub plugins32 and select FFMpeg Supported files filter when loading a video

You first have to look which kind of videofile you have : AVI, MP4, MOV, FLV, WMV, MKV, ...
These are called container formats : the way in which the video and audio information is stored in these files is different from one to the other.
An other thing is the way in which the information is encoded/compressed.
This is being done by so called codecs like
- H.264, DivX, Xvid, MPEG-1, MPEG-2, ... for video
- MP3, AAC, AC3, ... for audio
VirtualDub is able to open AVI files by default, and via installation of extra inputdriver plugins, it can also open other kinds of files...
In addition to VirtualDub you must also have installed the codecs that were used for encoding the video and audio
I suppose you actually have a MOV or an MP4 file with in most of the cases MPEG-4(AVC1)-video and AAC-audio ?
To open these kind of files you will have to install:
- the QuickTime plugin to be able to open MOV or MP4 files, AND
- Apple QuickTime itself OR "ffdshow" to be able to decode video and "AAC.ACM" to decode audio
Be aware that, if you installed VirtualDub 64-bit, you also have to install 64-bit inputdriver plugins, 64-bit codecs, and so on...
If you would install ffdshow 64-bit, then after installation : go into VfW configuration > Decoder-tab > and at H.264/AVC, change disabled into libavcodec. |
