No it's working fine here with gst-play-1.0 using omx (i hacked the priorities
in gstreamer to use omx decoding over vaapi). 
(media-plugins/gst-plugins-omx-1.12.4)

So now more testing for good luck..... 

<10 mins later>

I'll attach a gstreamer debug log for playing that file with omx,vaapi, and
xv/ffmpeg if you are curious. That proves 100% this issue isn't related to that
bug at all.


That ticket was a vaapi decoding issue. The test vector they uploaded also
plays here without problems with gstreamer 1.12.4. totem seems to crash on it
though but it's probably something to do with clutter and a very short file.

I made a longer file with this:
gst-launch-1.0 videotestsrc pattern=blink num-buffers=30   ! video/x-raw,
framerate=30/1   ! x264enc key-int-max=1   ! mp4mux faststart=true
movie-timescale=300 trak-timescale=30   ! filesink
location=i-frames-non-frag.mp4
