imx6dl gstreamer 1.0 playbin fails

[jefflancaster]

I am using imx6dl, Linux kernel 3.14 (yocto-dizzy), gstreamer 1.0, gstreamer-imx libraries, and all the necessary gst-plugins.

Problem: I can't get playbin to use the imx vpu library components, specifically the imxvpuenc_h264.

I built and installed the gstreamer-imx libraries:

I didn't have the h264parse plugin installed in my build. Now it works fine.

great, so gstreamer works fine totally, right? if yes, pls close this thread.

if you use the command "gst-inspect-1.0 | grep playbin", what can you get? any error message?

and what image do you use? demo image or built by customer?
