It would be possible to instruct the parser to throw an exception
containing some information about what is unimplemented under certain
circumstances. That would at least be an exit point. Unfortunately it's
not so easy to do anything with it because the plugin (which should
handle that) still does a fork-and-exec, so getting the information back
isn't so easy.

I'm also not sure how you want to get hold of the video URL
consistently. Flash videos (e.g. youtube) often rely on actionscript
interpretation to create the URL needed, and the parser doesn't do any
of that. Neither  is there an obvious way to work out which of the many
network connections requested is the video you want to watch.

The parameters passed to the SWF may be enough in some cases. Note that
the plugin has access to them. In the end though, some kind of browser
plugin that never even starts gnash may be a better way of doing this.


The current release of Gnash is 0.8.6
