--- Comment #13 from Tom Mitchell <tom at duotecno.be> ---
I also have the same problem with this pipeline. I use the latest sources from
git 1.11.01.

gst-launch-1.0 souphttpsrc location=<MY_URL> ! image/jpeg,framerate=10/1 !
jpegparse ! queue2 use-buffering=true ! omxmjpegdec ! videoconvert ! videoscale
add-borders=true ! video/x-raw,format=RGBA,width=800,height=480 ! glimagesink

I get the same error and I also have artifacts and stuttering video. 
CPU usage here is 90-110%.

On the version in the raspberry pi repository the same pipeline has to be used
with 'format=RGB', 'format=RGBA' doesn't work.

I have to use: 
gst-launch-1.0 souphttpsrc location=<MY_URL> ! image/jpeg,framerate=10/1 !
jpegparse ! queue2 use-buffering=true ! omxmjpegdec ! videoconvert ! videoscale
add-borders=true ! video/x-raw,format=RGB,width=800,height=480 ! glimagesink

CPU usage here is 23 - 30% and the video is displayed perfect.
