Okay, I first tried again with gstreamer after installing 
gst-plugins0.10-bad-0.10.10nb2 Open source multimedia framework - bad plugins
gst-plugins0.10-ugly-0.10.10 Open source multimedia framework - ugly plugins

But no noticable change. (I don't know what tool to use to test my 
gstreamer other than totem but don't want to install it now with 
libgnomeui. I also see that the gst ffmpeg plugin used its own provided 
ffmpeg.)

So I installed ffmpeg-20080727nb7 using pkgsrc (and lame with its unclear 
licensing). I used the ffplay (SDL frontend to ffmpeg) and it worked for 
me using:
$ youtube-dl 'http://youtube.com/watch?v=9sJUDx7iEJw'
$ ffplay 9sJUDx7iEJw.flv
(I could watch and HEAR the video "but they can't help their neighbors" :)

Then I did a gmake distclean in my source and then:

 CXXFLAGS=-g CFLAGS=-g ./configure --enable-gui=gtk \
--prefix=/home/reed/gnash --with-npapi-plugindir=/home/reed/gnash/plugin \
--enable-media=ffmpeg 2>&1 | tee configure.log.6

 time gmake 2>&1 | tee make.log.6

which failed here:

I am going to try to get this working from command-line before I pursue 
getting it to work in firefox.

Should I be using a newer ffmpeg version?

Should I use development code for gnash instead of 0.8.5 release?
