Title: videoplayer and videograbber working (tested on pandaboard)

some fixes to gstreamer player and grabber to make them work on arm, tested only on panda but it should work on rpi.

it works also with the hardware accelerated components of gstreamer but those need a color conversion step to upload to opengl texture (as opposed to hw overlay that is usually used by other players) that makes it slower than decoding on software. all this is done automatically, if the hw accelerated plugin is present it'll be chosen. on ubuntu-omap4 to deactivate the hw accelerated plugin:

apt-get remove gstreamer0.10-plugin-ducati

on the pandaboard the example that comes with OF works without dropping frames, h264 with 720x404 works ok setting the pixel format of the player to BGRA and more than that begins to drop frames. on the rpi installing gst-omx should give hw accelerated decoding
