The second patch is better, but still needs improvement by storing a required fixed scale mode in just one place, then setting it and refusing to change the scale mode if this fixed one was set.

For setting an initial scale mode that the SWF is allowed to change later, no patch is required.

Nevermind that question. Upon more investigation I found http://www.gnu.org/software/gnash/manual/gnashuser.html#gnashrc and answered my own question. Sorry.

See rc.h and rc.cpp. The closest to what you want is probably the quality setting, so you could look at that for a starting point.

Also bear in mind that there is a standard variable "salign" that you can pass in the FlashVars to a flash player (including Gnash). It won't prevent the SWF from changing the scale mode later, but sets the starting mode.

Hi Sandro

You right, but we'll probably have situations where we'd like to be able to force a particular type of scaling. If we're trying to play 3rd party swf's and their scaling has been incorrectly set for instance, it's an easy way for us around that issue.

I will look at developing it into an rcfile entry, but I'm not quite sure how that works yet, and this patch is not a priority project atm, as the current patch works.

However, I probably will be looking to develop a more solid solution soon, as updating the patch to match the trunk quickly gets tedious.

I wouldn't be against putting something like this in trunk, but there shouldn't be any need to clutter up the GUI like that.

Scale mode is a property of the Stage (movie_root), and there's no reason why Gnash can't provide an override. The simplest way would be an rcfile entry, which movie_root could check on construction (_scaleMode), and then refuse to change scale mode if requested by the SWF.
