Getting info from avi

Please bear with me here, as I'm verrrry inexperienced... First of all, I am using Visual C# Express Edition. I have been searching on the MSDN for some hours now trying to figure out these things, but I don't see anything that looks like it might be useful (or I don't understand what I'm seeing :p). First of all, I need to open an avi file and grab the framerate. I imagine this ought to be pretty easy, if I could figure out how :confused: Secondly, and I'm sure this must be far more difficult... I want to find the timecodes for each keyframe in the avi file. Thanks in advance if you can help this poor newbie to understand these things :)

check out MeGUI.. it does just that, and a couple more things with anything that AVIFile (VfW) can open. Keep in mind though, using open source code means you have to open source your program as well..

Look for MediaInfo lib, I use it in Realanime fo get infos on all my sources.

as far as keyframes go, there's the archanger program from the xvid forum that's also written in .net and which can identify frame types.

Thanks guys, this is probably what I need :)

Here is an examlpe of how you get the main info of an avifile using the vfw interface (vfw.h) in c/c++. The Keyword is AVIFILEINFO. Code:

Somebody is maintaining a C# avifile wrapper on CodeProject.

Wow, thanks guys. So many options :)
