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

So far I am able to run the following pipeline successfully till now.

However, it would be good if anyone can help me to run with
"imxeglvivsink". I am getting following error
##gst-launch-1.0 -v imxv4l2videosrc device=/dev/video0 ! imxeglvivsink
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.

Also not able to verify video encode and decode. Could you point me to
some standard video stream for decode I can test with (may be h264)
and from where can I download?

Dear All,
I am trying following command with gstreamer with imxeglvivsink on
i.MX6Solo but could not able to see working till now.
Could you provide some example pipeline commands to run with
imxeglvivsink? How could I fix the below errors? Any
inputs/suggestions?
How should I test my gstreamer setup with imxeglvivsink?
