Just a note -- at least in the past (when last I worked with this),
video card drivers/manufacturers put a hard limit on the number of
simultaneous xvideo output windows. In my case, I needed to display 8+
simultaneous videos and it was configurable and so xvideo was not a good
option for me. glimagesink allowed me to get past the hard limit and
provided reasonable performance. ximagesink (in the past) had poor
performance and some odd behavior (e.g., resizing the video window
mid-playback didn't update until the next frame was rendered. So with a
slow framerate video, it would behave funny). If xvideo isn't working
for you, you might look at seeing if there's a manufacturer-provided
driver with xvideo support.
