How can i open h264 video files in virtualdub?

Question

First the video files was mp4 then i converted them to avi files. Now that they are avi files when i try to open a video file in virtualdub i'm getting this error:

Couldn't locat decompressor for format h264 (unknown) virtualdub requires video for windows vfw compaitable decompress ...etc

What i did so far ?

Install ffdshow in configuration i changed not to disable h264 and all others in decoder.

I installed divx

I have virtualdub 1.10.4 Now i'm using ffdshow 32bit i tried 64bit before

I have windows 8.1 pro 64bit

Tried almost or anything i found in google nothing worked so far. I wanted to open the original mp4 video files in virtualdub but nothing worked so i converted it to avi but also not working.

What else can i do ? Maybe there is another program like virtualdub that it will work ?

Answer 1

You need to install the h.264 VFW codec here: https://sourceforge.net/projects/x264vfw/ Just close VirtualDub beforehand, and pick the default options in the installer. Worked like a charm for me.

AFAIK the file being MP4 or AVI is unimportant, it's just a change of "container", ie. what's inside both files is a h.264 encoded video channel.

Caveat: as mentioned by Ivo Kostić in another answer, it doesn't work well with interlaced x264 (I have no experience with that, I just thought this important fact should also appear in the "top" answer).

Answer 2

I used the VirtualDub FFmpeg Input Driver Plugin, Direct sourcforge page

1. Download
2. Copy files to the plugins folders in the virtualdub directory
3. Restarted virtualdub
