Compressed SWF format not supported

When trying to convert a .swf file to .flv in ffmpeg, I get this error. Is there any way to decompress or bypass this error in ffmpeg, or i开发者_开发百科s there any other command line video conversion tool that can do this conversion for me with a compressed .swf?

Yes, there are conversion tools, and one comes with ffmpeg actually. It's called cws2fws. You can find the source file at "ffmpeg_root/tools/cws2fws.c". I'm not sure if you need to pass additional options to your ./configure script to make it compile.
