Its really just a matter of exposing it over NSAPI with some decent messaging and thread management. In gecko-mediaplayer we now have an option to choose an alternate backend. One of those alternates is fosfor which is a clutter-gtk / clutter-gst application and we can embed that application in a firefox window (the window managed by gecko-mediaplayer). As for directly including clutter into a plugin. I don't see why you can't, especially with the clutter-gtk wrapper. I think what would be really interesting would be to use gobject-introspection and gjs to expose the Clutter API to plugins. Sand-boxing issues aside of course.

Re: [clutter] How to compile clutter-mozembed
I've not added the API to do this yet, I'm afraid. It's not a priority, but patches welcome. I'd suggest that the cluttermozembed should create a shared memory segment, write the data to that segment, then send a message to headless along the lines of 'render-html shm-name', then block for a reply (something like 'html-rendered'), after which it can free the shared memory segment. --Chris On Mon, 2009-05-11 at 14:31 +0800, Yao wrote: Hi, All: I have built mozilla-headless and clutter-mozembed successfully. and Tests under clutter-mozembed/tests works well.

Kiran I don't know how it changed lately, but the scrollbar you see is hardcoded in tidy, so it displays always. The only solution is to modify the source and remove the calls to (off my head) scrollbars_show. I don't remember which object exactly, but one related from the viewport to the finger_scroll_view. Mike TidyFingerScroll is an extension of TidyScrollView. To hide the scroll-bars permanently, you can set the size of the scroll-bars to zero by using tidy_scroll_view_get_[hv]scroll_bar() and setting the 'xthickness' and 'ythickness' stylable values using: tidy_stylable_set (TIDY_STYLABLE (vscrollbar), xthickness, 0, NULL); tidy_stylable_set (TIDY_STYLABLE (hscrollbar), ythickness, 0, NULL); I'd recommend doing it this way rather than changing the Tidy code. Other tricks, if you set the scroll-bars reactive, they'll remain visible permanently too (and will be interactive). -- Chris Lord, Intel Open Source Technology Centre -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com

Ok, a bit of testing on an Ubuntu Hardy based system seems to suggest that this is due to either the X driver (Intel i915) or buggy libraries on the Intrepid system. Yes, unfortunately Ubuntu have picked a buggy driver revision. A temporary fix is to disable text mip-mapping (note that you'll have problems using high-quality textures too, but the default settings for this are fine). You can do this application-side, with clutter_set_use_mipmapped_text (FALSE); before creating any ClutterLabel/ClutterEntry actors, or you can patch Clutter itself. In clutter-main.c, search for the line pango_clutter_font_map_set_use_mipmapping (ctx-font_map, TRUE); and change 'TRUE' to 'FALSE'. This will affect all Clutter applications and fix the problem.

Note that I've not tried this code, so it may not work... Also,
adjusting the scale properties linearly may not produce the results you
intend (instead, you may want to multiply scale_x/scale_y, or have
preset values). Also, you'll want to put upper/lower bounds on the
values they can take too.
Hope that helps,

RE: [clutter] Comments about new texture-from-pixmap feature
I've been looking at this and have been coming to the same conclusion. You could pack the yuv (444, 422, 420, whatever) data in an arbitrary way into an RGBA texture and use shaders to translate to real RGBA. This would avoid the multi-texturing, but I imagine you'd still have to munge the data to get it into a format that's convenient to read by shader (so probably not the memcpy, or equivalent). A fall-back would require multi-texturing though, and I agree that this is probably best off in the clutter-gst layer. Implementing this at the cogl level will likely over-complicate a lot of code and restrict expandability. --Chris On Tue, 2008-07-01 at 14:31 -0400, Kashyap Ashwin wrote: Is this even possible to do without memcopying data around?
