<div>Hi. I've been trying to play either a udp h264 stream or a
video file with hardware acceleration.<br>

With this command I get VERY choppy playback, low cpu usage and
a lot of banding:<br>

Adding a small queue after the decoder at least would decouple video
decoding from actual rendering which probably helps here.<br>
<br>
As you have low CPU usage I assume you built gst-omx and
gst-plugins-bad correctly for zerocopy decoding which is good :)<br>

horrible.<br>

Similar thing (banding, low fps, low cpu usage) happens with:
<br>
gst-launch-1.0 filesrc location=file.mp4 ! qtdemux ! h264parse
! omxh264dec ! glimagesink<br>

<div>I compiled this version on my own, I'm running 1.11.1 right
