Following my dumb Q about MPEGs a couple of days ago it was suggested
I'd be better off with AVIs, so I've moved on to AVIs and picked up Ronn
Kling's AVI code from http://www.kilvarock.com./freesoftware/dlms/dlms.htm
It seems to do the generate test okay, and subsequently read back the
avi it generated, but everything goes pear-shaped and IDL crashes
horribly if I try to import a short AVI I've just saved from a movie
capture program called PowerDirector, using the maximum quality option.
That movie plays okay in VLC and Windows Media Player.
It falls over reproducibly on different machines, and as well as 7.0 I
loaded up a copy of 6.3 just to make sure nothing had changed in IDL to
break it.
Anyone have any ideas what might be going wrong?
Ta, pete.

never did fix it, despite trying lots of alternative codecs and options,
so who knows...? However, I did find an alternative which is an AVI
reader for ImageJ which lets me save everything out as individual
images, so it's one step extra but /relatively/ painless and if anyone
else is suffering with AVIs this is one way around.
With a bit of luck Ron's revised version will help troubleshoot it when
it's out.
Pete.
