Unable to load AVI file into VirtualDubMod?

Postby hikary22 » Wed Jun 29, 2011 4:35 am

I'm trying to hardsub an AVI file. But when I try to open the video file in VDM, it kept giving me this :

Couldn't locate the decompressor for format 'avc1' (unknown). VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable. Only 'Direct streamy copy' is available for this video.

What should I do to be able to load the AVI file? And what is avc1? Am I missing a plug in or a codec or something? Is there anything else I should install? And how to do it?

Your kindness would be such a great help to me! Thanks a bunch! :D

.. convert it with another program or .. or get the help of AviSynth.

Virtual Dub, as far as I know, won't accept the avc1(H264) unless
you use a Codec Pack designed for the "avc1" codec.

I'm usually one of the last ones to recommend Virtual Dub to newbe's
because I believe they can get more accomplished with AviDemux.

.. Now, I'm under the impression that AviDemux is not favored on this site.
( this may be true however, it can solve more issues with Codec's than
Virtual Dub can -- -- this is just my opinion. ) and .. .. umm .. well,
I've never had a successful video load through any FFMpeg nor AviSynth
program to date [ that does not mean that it can't be done; it does
mean that "I've never gotten it to work "right" for me." ]

.. Virtual Dub Mod works quite well with Mpeg-2 ripped files from DVD's.

First question is, did you encode the avi yourself? If so, don't encode h264 to the avi container, use mkv, or mp4. if not, then you can try to open the video using avisynth. You'll need ffmpegsource2... the script should look something like:

Code: Select all

v = ffvideosource("pathtofile.avi")
a = ffaudiosource("pathtofile.avi")

You should be able to load the script into vdub to do what you want. While you're using avisynth, you can add your subtitles in the script also using the same vdub plugin (textsub):

Code: Select all


Hope that helps. if you need assistance with Aviysnth, be sure to read the av guides here on the org.
