Swfdec - Dec 2007 - Lots of problems playing back !

Hi all,
I got swfdec compiled and running, however there are a lot of problems
running it !

As a test I tried:

swfplay http://www.youtube.com/v/lUR6laFLk0A

First of all I see:

SWFDEC: ERROR: swfdec_codec_gst.c(231): swfdec_gst_decoder_init: failed to
create decoder
SWFDEC: ERROR: swfdec_codec_audio.c(192): swfdec_audio_decoder_new: no
suitable decoder for audio codec 2
SWFDEC: ERROR: swfdec_codec_gst.c(231): swfdec_gst_decoder_init: failed to
create decoder


Second, transparency seems broken - for example, around the "play"
button
in the centre of the screen, and the little spinning circles.

Third the video is not playing (I guess it's related to the missing codec
above ? however there is no indication as to what I need to install to
play it).

Fourth, the buttons (pause/play) and slider bar are VERY unresponsive, and
when pressed, artifacts appear in the image screen.

Fifth, resizing/exposing the window is broken, the image doesn't seem to
redraw.


I guess you are working on these issues, and I realise the project is
still in early development, but as I said, at least some indication of
what codecs are missing and how to install them would be nice.

If you are using a recent version of swfdec (0.5.5 or a revision from
the git repository), it uses gstreamer by default, so you need to
install non-free gstreamer codecs.  This is distribution specific.  On
Fedora, I add Livna repository and install gstreamer-plugins-bad and
gstreamer-plugins-ugly using yum.  That pulls some dependencies as well.

Another approach is to install mad and ffmpeg with development libraries
(again, you'll need some unofficial repository) and recompile swfdec to
use them:

./configure --enable-mad --enable-ffmpeg

The other problems may stem from the missing codec, so please recheck
that they persist once the codec issue is solved.

You must have installed gst-ffmpeg (or whatever it's called on your
distro) to be able to see video and gst-plugins-bad for mp3 audio
decoding. Alternatively, you can use the --enable-ffmpeg configure
switch, but that's not recommended.

Nope, that's not transparency being broken but the image. For some
reason it's not repainted properly, but I haven't yet figured out why.
It's a bad first impression for people new to Swfdec, but it's not
really hindering playback so it wasn't worth delaying a release for
it.

That is true, but then, Swfdec has no clue about it either. In theory
your distro should take care of that, but I don't think Debian or
Ubuntu suggest gst-ffmpeg and gst-plugins-bad on package install?
(side note: This was more of a question to the packagers reading this)
And hooking up something like Codeina is not as easy either, because
you don't want to get a "missing codec" window from the
thumbnailer or
the testsuite. So it's somewhat of a hard problem, but we take
patches. :)

The artifacts are probably related to the bug above. Unresponsiveness
is a general problem with bad X servers (search the archives for "EXA"
to get help on that), but could also be related to the missing codecs.

See above.
