Re: [gst-embedded] Need Help In Totem Media Player

[Tejas <te...@pi...>]

Hi Felipe,
	Nice to have reply from you. I have gone through gst-omapfb plugin from your git repository of gst-omapfb. I find it works on omap frame buffer and accept format as "UYVY". So I can give my decoder output in the form of "UYVY".
	I have one question, when I run my Plugins as gst-launch, I can run VGA and also HD file smoothly. But when I run into totem movie player, I can't run 320X240 video file smoothly.

	If I remove ximagesink and xvimagesink Plugins from my library path and put omapfb plugin there will totem work ?

GStreamer would find out if there's any conversion needed (of the
elements are implemented properly). Maybe you should give a try to
gst-omapfb which renders directly into the framebuffer into a YUV
overlay.

Unfortunately the OMAP3 display subsystem doesn't support I420 so you
would need some conversion for sw codecs. Or you can try to use the
DSP accelerated codecs which have an accelerated converter.

I know FFmpeg guys have been able to decode 720p videos smoothly on
the beagleboard so it's definitely possible. You just need to plug the
right pieces :)
