Where's the patch to do it? I was going to hack on that with Alp
Toker, so if we had something to start, that'd be great.

This definitely works by Swfdec 0.4.5 - 0.4.5 plays Youtube after all.
It can be that it misinterprets some stuff in the xxx.swf file and
therefore never gets to loading the FLV. That would then be a missing
feature.

If you do your own SwfdecLoader subclass (see the swfdec-mozilla
loader for example), everything should just work. The Mozilla plugin
loads progressively just fine. For testing purposes, swfplay -d 10
will make loading the file take 10 seconds time.

That's a bug in older versions of ALSA or libc. It's fixed in Ubuntu
Gutsy's version. You can locally use Robert's suggested fix for it
until that bug is fixed upstream.

That again is a bug in upstream ffmpeg. Swfdec uses -Werror on purpose
during development so that these bugs get fixed. Releases compile
without -Werror, so yeah, you can just use CFLAGS="-Wno-error"
./configure to get rid of it.

That is indeed a bug, that I'll immediately fix. I blame Robert for
not complaining yesterday. ;)

Ooops, yeah I forgot about readding this during the 0.4 => 0.5 port.
It's somewhat of a hack anyway, but I should get around readding that
before the next release.
