Dear All,
I have some problems with the examples provided in the document i.MX 8 GStreamer User Guide .
I am using MCIMX8M-EVK board(i.MX 8M Evaluation Kit | NXP ) and "L4.19.35_1.1.0_MX8MQ" imx-image-full-imx8mqevk.wic image from the link (https://www.nxp.com/webapp/Download?colCode=L4.19.35_1.1.0_MX8MQ&appType=license ) provided in the document. (Chapter 1.0)
root@imx8mqevk:~# uname -a
Linux imx8mqevk 4.19.35-1.1.0+g0f9917c56d59 #1 SMP PREEMPT Wed Oct 30 13:39:09 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux
But it seems that some i.MX Proprietary Plugins (Chapter 2.4) are not usable.
gst-inspect-1.0 only lists vpudec as proprietary plugin.
root@imx8mqevk:~# gst-inspect-1.0 |less | grep imx
root@imx8mqevk:~# gst-inspect-1.0 |less | grep vpu
vpu: vpudec: IMX VPU-based video decoder
root@imx8mqevk:~#
And the following command gives the error below.
root@imx8mqevk:~# gst-launch-1.0 -v imxcompositor_g2d name=comp sink_0::xpos=0 sink_0::ypos=0 sink_0::width=640 sink_0::height=480 sink_1::xpos=0 sink_1::ypos=480 sink_1::width=640 sink_1::height=480 ! waylandsink videotestsrc ! comp.sink_0 videotestsrc ! comp.sink_1
WARNING: erroneous pipeline: no element "imxcompositor_g2d"
I think this issue is related with thread imx-gst-plugin for imx8 returns 0 features
In this threadigorpadykov also suggests to use latest L4.19.35 image, but problem still remains.
I have also built a Yocto image and faced the same result. I would appreciate if you can help.
Kind Regards,
Burak AYDIN
