[E-devel] Is there any efl object instead of gtk.drawingarea ?
hi all, You know that Gstreamer video often is displayed in drawingarea which is created by gtk.Drawingarea() function, Is there any efl object instead of this function to create a drawingarea to display Gstreamer video. Any examples would be welcome :) Thanks!

hi, thanks, I think you should know about canola I think the media part of it is implemented by Gstreamer. Am I right ?

We should look at libplayer (libplayer.geexbox.org), which is a wrapper that controls mplayer process in slave mode, After that, as Gustavo said, write a buffer vo for mplayer like it's done in vlc. AFAIR mplayer can be only controlled in slave mode. my 2 cents. -- Nicolas Aguirre Mail: [EMAIL PROTECTED] Web: http://www.digital-corner.org - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel

On Mon, 3 Nov 2008 16:20:23 +0100 thomasg [EMAIL PROTECTED] babbled: Because of that and many many other reasons it would be really cool, to have a mplayer backend for emotion. :) that is impossible as mplayer has no interface to provide yuv data to a caller. thus no backend exists. until mplayer has such a facility (out of the box - without patching mplayer) an emotion engine can never exist. emotion is not the most efficient video player - in software rendering it does software yuv-rgb(32) conversion then scales in rgba space. the performance is actually quite astounding considering how much it actually does going the long way. if you use the gl engine its the same efficiency as mplayer/xine with xv. the yuv-rgb + scaling is done in hardware (with a fragment shader) and the upload to video mem is the same path as xv pretty much, so you'll see the same cpu overhead there with full emotion + scaleable/fadable/layerable objects and just regular boring xv. But I know, it's really tricky to find a good solution, because mplayer isn't meant to be just a backend.
