Re: Writing JPEG-encoded movies without QTJ



Thanks for the AVI link.  :)  I bookmarked the site for future  
reference.

Also of interest:
Werner Randelshofer ripped apart my JPEG-movie-encoder classes and  
rewrote them:
http://blog.hslu.ch/rawcoder/2008/06/21/writing-quicktime-movies-in-pure-java/

His implementation is more compact than mine; I highly recommend it.   
Also his encoder supports PNG movies (which is great for truly  
lossless encoding).

In coming months I'll probably try to add MP3 audio tracks to movie  
files manually, too.  (I'll probably refer to Stuart MacKay's SWF- 
writing library; I know it can break MP3's down into packets/samples.)

Regards,
- Jeremy
