[yocto] MP4 Playback Issue with GST-1.0

[Carlos Rafael Giani]

Hello,

it would also be useful to know if this happens on the PC as well. If 
so, then asking the GStreamer developers may be more appropiate.

Also, the GStreamer 1.0 version in Dora is 1.0.9 , while the one in 
master is 1.2.2. There have been significant h264 related fixes between 
these two.
