Hi.

I'm looking for a good tutorial that will help me to understand how to use C++ api to create an avi file.

Thanks.

Do you know much about video? Do you know the difference between i frames and p frames. PAL? NTSC? Frame groups? Inverse telecine?

I am actually working on audio/video sychronization right now and let me tell you. Things can get pretty tricky sometimes. And this is just editing, we're talking about here.

I don't mean to discourage you, but if you're justing messing around, I highly recommend you start off with wave files. If you can hex edit, you can pretty much handle that with ease. Video is complicated, mostly because of renderers and codecs. But pure avi by itself, is just bitmaps laced together,
with sound samples at each frame.
I think it may be more fun for you, if you do as much as you can by yourself

You'll probably want a hex editor by the way

Here are some basic steps for video
--this is before your delve into avi

1) write a program that read and render bitmaps
2) write a program that can stream bitmaps into an animation

--familiarize yourself with avi

3)if you have an avi recorder, use it. make simple little videos. change the resolution, see what happens. change the sound quality. change the picture.
change the fps
4)learn the parameters, somewhere in the header of the file i do believe. (as far as i know the frames in an avi have no connection with each other.)
5)write a program that isolates video from sound(demuxer in other words)
6)write a program that plays both the video and the sound. tadaa!!!
7)write a program that captures video. if you don't want to bother with capture drivers and all that, then trying using the printscreen then copy the contents of the clipboard and dump it into a bmp.(atleast 24fps, but you'll probably want to make that adjustable anyway.)

If you can actually make an avi player or editor with just the information above, I salute you. Because to be honest, I have'nt made a functional one yet. I know more about video than C, sadly. Which is pretty bad considering, I'm not even studying to become a video editor.
