CODA VPU initialization failure with Gstreamer

[João Rodrigues]

Hello.
I am trying to use GStreamer in an iMX.6 SoC with the mainline kernel (4.13.x), with the aid of the CODA vpu driver.
Although, when i run gst-launch-1.0 playbin uri=file:///home/root/test.mp4, i always get the following kernel message:
[  386.336530] coda 2040000.vpu: CODA_COMMAND_SEQ_INIT timeout
I have tried various things by now, but was never able to generate an output.
I can only generate an output on my screen with gst-launch-1.0 videotestsrc ! autovideosink (fbdevsink also works)
Looking forward for a solution
Extra debug info:
CODA is initialized properly by the kernel;
the sink used by gstreamer is imxg2dvideosink (Which i think it is one of the sources of the issue)
CMA memory is set to 64MB (320 MB does not fix it)
Gstreamer ver - 1.8.0

In the meantime I have tried with GStreamer 1.12, same results

Best regards,
João Rodrigues
