Detecting QPEL and GMC with VB6

[marnix88]

Hello, I'm making a codec finder, which shows information about AVI videos. I have almost everything the way I want it, but I'm still missing some important information. I'd like to show information whether the video was encoded with QPEL, S(GMC)-VOP, B-VOP and N-VOP or not.

Does anybody know how to get his information with VB6?

Thanks.

Is there really nobody who knows how to get this information?
Are there other languages that can get this information?

I looked at the source code of mpeg4modifier, which is written in C#, but I have no idea which part of the code I exactly need.

Look at ParseVOL() and ParseVOP() in MPEG4FrameModifier.cs. The flag for QPel is stored in vol.quarterpel, and the frame type is in vop.vop_type.

Thank you, Moitah.

I wish that somebody would translate those parts to VB, but I doubt anyone is willing to do that.

At least now I know which parts to look at. Thanks again :)

How did you go ? I'm also stuck with VB6 and some code would come i handy ...
