  I'll try to expand this, but here's a start on my notes for Nomad:

  Good luck. From looking through the Nomad SDK, Gstreamer appears to 
be only partially installed. You might have better luck with ffmpeg 
directly. I did fix Gnash's configure to better handle a broken and 
partially installed Gstreamer, so it'll now build fine. I just had to 
disable some features, like auto-probing for input devices like a 
webcam. (you can set this in your .gnashrc file anyway)

  I used the newer one, with my changes.

  Which I cleaned up an reorganized to work the standard way. The 
improved sysroot that successfully builds Gnash is at:
http://www.gnashdev.org/tools/sdg/arm-angstrom-linux-gnueabi.tar.bz2

  All fixed in trunk as of revno # 11502.

  I changed g_strcmp0 to strcmp where I found it. The other issue is 
pbutils headers are installed, but not the library support. This is now 
fixed in trunk. The other problem was the Gstreamer headers wanted 
libxml2 headers, which we don't look for. When building native, we use 
pkg-config to get the flags, which include libxml2. When cross 
configuring with no pkg-config, we have to find all the pieces of 
Gstreamer ourselves. So I had to add libxml to the sanity check of what 
is found.

  Just a glib dependency missed cause of cross-configuring.

  Also fixed.

  My newer build is at: 
http://www.gnashdev.org/tools/sdg/gnash-nomad.tar.bz2. This is trunk as 
of revno #11502. I don't have any Nomad hardware, so I can't test it. 
(add begging for cool hardware here... :-) )
