title: What does it mean for a .swf file to be compressed?
body: <p>I tried converting a .swf file into .avi through ffmpeg, and I got the error 'compressed swf format not supported'. How does a compressed .swf differ from an uncompressed .swf file? How do you specify which one you want to make, and is it even possible to? How would you decompress a compressed .swf and what should you expect to find? I googled a lot of these but I didn't manage to learn much from the bits and pieces I found.</p>
