[meta-freescale] Gstreamer1.0_1.4.5 with imxeglvivsink errors

[Carlos Rafael Giani]

First, this pipeline is incorrect:

gst-launch-1.0 filesrc location=/home/root/song.mp4 ! h264parse ! 
imxvpudec ! imxipuvideotransform ! imxg2dvideosink

it should be like:

gst-launch-1.0 filesrc location=/home/root/song.mp4 ! qtdemux ! 
h264parse ! imxvpudec ! imxipuvideotransform ! imxg2dvideosink


Second, without log output it is impossible to say anything. For exampl, 
run this pipeline with the GST_DEBUG environment variable set to 
"2,*imx*:9"  :

gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxeglvivsink


Third, does this work?

gst-launch-1.0 imxv4l2videosrc device=/dev/video0 ! imxg2dvideosink


Fourth, the fact that this produces a "could not determine type of 
stream" error indicates that your mp4 file is broken:

gst-launch-1.0 filesrc location=/home/root/song.mp4 ! decodebin ! fakesink
