i have downloaded a program named mpgtojpg which says it can extract jpg files from mpg or avi file formats. but sadly, it doesn't live to its name. it crushes when it tries to do the work.
i needed this type of program since i am going to extract picture files from a video of some of our organization's activities for our photo album.
can we do it in vb? pls help me how to do this one, i'm below newbie when it comes to graphix with vb... :(
could you please elaborate more on that, like which one are you using, plus if you have some information on its system requirements, may be we can help you out.Quote:

Do you want to extract every single frame as a jpg?
if its possible... or anything as long as i can extract a picture from a video file...
You could always find the place you want and hit Print Screen.

This program captures video and images from a video input device, maybe helps you if you take a look at its sourcecode.

actually I'm still in the progress of trying to do that kind of software using VB.
anyway, I can recommand you a software, it does extract a video file to graphic files. you may try search on the internet for this software ---> "BPS Video Converter & Decompiler"
hope this info is not too late for u :)

Video files are more complex than you'd think for the sake of compression, although I believe mpg's in general are simpler than most.. Perhaps the software was designed for an older mpg format, perhaps its garbage.. You can easily get VB to auto screencap, (there are samples out there) but you might be opening a pandora's box by trying to decode frames.. However if you do it, Post it..:)
If this is more about extracting frames than finding the code, I've been using The Gimp with the Gap extension, and Media Player Classic to extract frames from Mpeg. The Gimps gap extension is perhaps the more powerful (and complicated), letting you specify a page range to extract. They both come under the GNU General Public License. I've had no problems with them.
Edit: I'm also using the (again GPL) ffdshow codec.
