File Information

AVILIB is a simple wrapper for ML's basic AVI engine to easily create AVI movies using the more
familiar low-level file-i/o syntax of the form:

- aopen : open an AVI file
- awrite : write to an AVI file
- aclose : close an AVI file

takes image(s) of the form
- RGB (x/y/3)
- INDEXED (x/y)
- getframe(...)

performs extensive error checking on subsequent input(s)
- size
- bit-depth

for further explanations see:
     help aopen
     help awrite
     help aclose
     help avilib

for i=1:10
% if used in a wintel (2k/xp) env
% with <windows player> installed,
% this will show the movie right away:

     set(gcf,'position',[100 100 200 200]);
for i=1:10
     aid=awrite(aid,f,r,{f r;f r});
% !goo.avi

For me aopen command does not work.Why?
>>Undefined function or method 'aopen' for input arguments of type 'char'.<<

This is absolutely excellent! I'll never use Windows Movie Maker again!

Just one thing to note is that a few more usage examples might be useful. For example, framerate is set using: "aid=aopen('-f','foo','-d',32);" ... not "aid=aopen('-f','foo','-d','32');" or "aid=aopen('-f','foo','-d 32');" etc.

This may be obvious, but it could save some people a little time.

good tool and easy to incorporate in one's own routine. I was stuck trying to write frames into avi files after processing them. This is fast and efficient. Thanx a ton
