could not link amcvideodec-omxgoogleh264decoder0 to glcolorscale0

Sun Nov 8 19:28:59 PST 2015

OK, it turns out I needed a videoconvert in there to go from I420 to
RGBA. I'm not really clear on why that wasn't necessary for
glimagesink, but that's another problem for another day.

My new issue is that glupload seems to fail after a few frames and I'm
not sure why. Except below and full log here:
http://pastebin.com/T8fT88YW

My appsink callback code is here: http://pastebin.com/p8VWZ8wb

Any thoughts?

Thanks
