[Gnash-dev] checking ffpmeg in ./configure is broken

[John Gilmore]

In today's CVS source tree, I ran autogen.sh and then:

  ./configure --enable-renderer=cairo --enable-gstreamer

Among the output, it seems to have ignored the --enable-gstreamer,
because it's looking for ffmpeg (which I don't have) -- and then its
shell script is flaking out:

...
checking for ffmpeg header... Package libavcodec was not found in the 
pkg-config search path.
Perhaps you should add the directory containing `libavcodec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavcodec' found

If we're moving to using "--enable-media=", do we need or want the
"--enable-gstreamer" option?

By the way, --enable-media=gstreamer doesn't work.  It says
"configure: error: bad value gstreamer for --enable-media option".
For some reason it wants us to call it "GST" rather than
"gstreamer".  I don't think the saving of six letters is worth the
confusion.

PS:  I also couldn't figure out how to install Ming & MTASC in Fedora Core.
Does somebody know what Fedora named these packages?
