The other day I wanted to create a GIF anim from a short part of an AVI, so I started searching for a program that would do that for me. Most of the programs I could find were ones that cost money though, which I found odd because it seemed like a relatively easy thing to do. Now, surely there must be some free programs like this but I didn't have the patience to go through all the search results.

So yesterday I started writing a program for this myself, and now the first version is done. It's very minimalistic so far; it's a command line application and only has a few options, such as starting frame, length, playback delay etc. There's not a whole lot of error checking either.

Since it uses VFW for video decoding you need to have the necessary codecs installed for whatever AVI you want to convert. A possible improvement for the future might be to add support for AVS files using AVISynth, so that you can read MPEG files, as well as getting access to all the AVISynth filters.

I've submitted the program to the archive - in the meantime you can get it from the link at the top of this post.

I just finished a GUI in Win32Lib for this. However, neither the original command line program nor my GUI convert the AVI correctly. On line 136, aFrame is zero. I assume that's supposed to be a handle of some sort, but there is no check for it the value to be nonzero. I added a check for this to my GUI, so it never gets on to the actual transcoding.

aFrame = AVIStreamGetFrameOpen(aStream, {40, sAviInfo[6], sAviInfo[7], 1, 24, 0, 0, 0, 0, 0, 0})

That means you either don't have the necessary codec installed, or that codec doesn't support decoding to 24-bit RGB. The example video that I included with the program uses DivX iirc.

Anyway, like I said in my previous post, passing .avs files to the program works if you've got AVISynth installed. So if you've also got FFDShow installed the DirectShowSource function in AVISynth should be able to decode pretty much anything (except MPEG2 maybe, but there's a plugin for that).
