Hello, I am using imx8mp now. instead of using yocoto, I have install a ubuntu file system on the board. but now i'd like using opencv2 gstreamer plugin to get rtsp video to handle it. but now I can't using hard decode plugin which result in a more than one secode frame delay . wonder how to build and install it on the board directly? Thanks.

best regards.

Hi @a1012112796,

I hope you are doing well

To build the GStreamer imx plugin please refer to the following document.

Freescale/gstreamer-imx: GStreamer 1.0 plugins for i.MX platforms

Hi @a1012112796,

One can check the available library from the command 'ldconfig -p | grep <lib_name>'.

Please check if you were able to find the libhantro.so and libcodec.so under /usr/lib? they are a hantro library.

Q)how to get `hantro`?

=> To get Hantro packages, one needs to add below 2 lines in the $BUILD/conf/local.conf file.

IMAGE_INSTALL_append = " imx-vpu-hantro"
IMAGE_INSTALL_append = " imx-vpu-hantro-vc"

The more information related to Hantro, kindly refer to section 6.7 Video Processing Unit (VPU) from the i.MX Linux Reference Manual.

Thanks & Regards,
