We are using imx6 quad sabresd.

we use yocto morti. yocto morti was added with gstreamer plugin from community.

We try a very simple test with gstreamer:

gst-launch-1.0 testvideosrc! video/x-raw,width=1280,height=1024 autovideosink.

The video appears in rate slow on screen , and there are warning that the cpu is too slow.

With "top" we see that it get 100% cpu usage.


Does it make sense that such a simple pipeline gets 100% cpu ?


We also tried to test with yocto jethro, but get the same behaviour.

yocto jethro does was not added with community plugin.


We also wanted to verify that gpu workjing, but trying to execute the test fails (in both yocto images...):

The gpu test does not work (it says it is missing /opt/viv... / is imssing)


Do you have the same result under you imx6 quad sabresd or are we  using gstreamer in some wrong way?


Thank you,
