imxg2dvideosink does not work

[emustafa]

Hi everyone.

I am using Debian Jessie image for hummingboard IMX6. I compiled version 0.12.0 of https://github.com/Freescale/gstreamer-imxand installed it. I can use imxipuvideosink just fine. However, I can't get imxg2dvideosink working.

When I try the following pipeline:
gst-launch-1.0 videotestsrc ! imxg2dvideosink

I get
$ sudo gst-launch-1.0 videotestsrc ! imxg2dvideosink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

After it just hangs. The same pipeline works fine in Solidrun's debian jessie image. I am looking for suggestions on how to fix this issue.

I don't know what information to paste here. Here is the output of uname -a
$ uname -a
Linux cubox-i 3.14.67-cubox #2 SMP Fri Apr 29 03:34:19 CEST 2016 armv7l GNU/Linux

The dmesg output when the pipeline runs is:

Thanks.

There are two kernel sources, both has issues on their own. Our default kernel works but has problems in video / camera area, while new kernel (our imx DEV branch) works good in video area and lacks of PCI support.

 

Our core mission is to have basic good working image and sometimes we go extra mile to provide video acceleration or similar. I already spent waste amount of time to fix this but failed.
