It looks like:
a) It's attempting to play the file with FFmpeg's SWF playback, not
swfdec
b) FFmpeg is throwing an error code (one that our demuxer wrapper
doesn't recognise) when it first starts trying to play the file
c) You're probably not going to have much luck playing swf files with
GStreamer - the swfdec wrapper was written for swfdec 0.3, and never
been updated since - and as you see, the playback via ffmpeg isn't very
good except for some few files.
