Is there some library for reading an avi-file and extract the pictures, frame by frame? Would that be the same as a codec? And in that case, which codec should I use? Any free avi library/codec would work.

What about libraries for reading other formats such as mpg, wmv, etc.?

Avi is a container. It contains compressed data which is compressed by a codec.
The easiest thing to parsing these kinds of things would be DirectShow I imagine.
FFdshow is a filter that can decompress almost any type of video/audio and Haali's Media Splitter is a filter that can split all popular container types (mkv, mp4).
Avi and wmv are typically already installed on a windows machine.

This is assuming you are using Windows.

I am using windows, but I would prefer to use a platform independent library so my program gets portable. I somewhat like SDL, does that have functions for viewing frames in avi-files? Do I need one tool to get the data out of the container and one tool to decompress the data, or is this usually done at the same time?

[quote=TriKri;760841]No to my knowledge. It's mostly a graphics API and an input API I think.
It's not for media viewing or extracting.

Typically you will need two.
One to extract and one to decompress (the appropriate codec would do that).

I don't know of any cross-platform library, but if you aren't scared of command lines, then you could try using mencoder. It's cross platform and compatible with lots of things.

Thank you. I have found this site, which I will take a look at. I will also take a look at mencoder, maybe it's usefull.
