How to compress an uncompressed avi file into MS-CRAM

I had faced up with same issue in my project. So I made some changes in the code.

In VideoStream.cs
Uncomment <pre> /*Avi.AVICOMPRESSOPTIONS opts = new Avi.AVICOMPRESSOPTIONS();
opts.fccType = (UInt32)Avi.mmioStringToFOURCC("vids", 0);
opts.fccHandler = (UInt32)Avi.mmioStringToFOURCC("CVID", 0);
opts.dwKeyFrameEvery = 0;
opts.dwQuality = 0; // 0 .. 10000
opts.dwFlags = 0; // AVICOMRPESSF_KEYFRAMES = 4
opts.dwBytesPerSecond= 0;
opts.lpFormat = new IntPtr(0);
opts.cbFormat = 0;
opts.lpParms = new IntPtr(0);
opts.cbParms = 0;
opts.dwInterleaveEvery = 0;*/</pre>

and replace these two line <pre>
opts.fccType = (UInt32)Avi.mmioStringToFOURCC("vids", 0);
opts.fccHandler = (UInt32)Avi.mmioStringToFOURCC("CVID", 0);
</pre>

with
<pre>
fccType = (uint) Avi.streamtypeVIDEO;
fccHandler = (uint) Avi.mmioFOURCC('X', 'V', 'I', 'D');

</pre>

Now comple the project and use this dll in your project.
This will prevent the dialog to be appear... Hope this will help..
