How to Cross Compile GStreamer for iMX8M Mini using Yocto

msingh1920 — Tue, 07 Dec 2021 14:35:39 GMT

Hi Sir,

I am using iMX8M Mini and Yocto imx-linux-hardknott imx-5.10.52 version.
But default GStreamer provided in iMX yocto does not support the GStreamer C application it only supports the command line.

Hence I need to install and compile GStreamer using iMX yocto.

To do that I did the following steps -

1) I added the following code to local.conf file ->

IMAGE_INSTALL_append += "gstreamer1.0-rtsp-server gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav"

LICENSE_FLAGS_WHITELIST = "commercial"

2) After that I compiled and build the SDK and flashed it to iMX board.

but when I try to compile a simple GStreamer hello world application on my imx8 Mini board then
It gives me an error saying -

fatal error: gst/gst.h: No such file or directory
#include <gst/gst.h>

It seems like even GStreamer is compiled successfully but the header files are missing on SDK.

please suggest to me what I am missing and how can I cross-compile the GStreamer with iMX yocto

NOTE:->
I am doing the following steps to compile the iMX yocto ->

DISTRO=fsl-imx-xwayland MACHINE=imx8mm-lpddr4-evk source imx-setup-release.sh -b build-xwayland

bitbake imx-image-full

Thanks

Hi Maneesh

one can look at gstreamer tutorial from Gateworks:

Hi @igorpadykov

Thanks for your reply.

I am able to test and run GStreamer plugging from the command line but I want to use GStreamer C code and Default GStreamer provided by iMX BSP doesn't support GStreamer C code

Hence I need to cross-compile the GStreamer library for iMX BSP using Yocto.

I am using -
EVK :- iMX8M Mini EVK
Yocto version :- imx-linux-hardknott
Version :- imx-5.10.52 version

To cross-compile GStreamer I am adding the following lines in local.conf file ->

IMAGE_INSTALL_append += "gstreamer1.0-rtsp-server gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav"

LICENSE_FLAGS_WHITELIST = "commercial"

But seems like GStreamer cross-compilation is not working because when I try to compile a simple GStreamer hello world application on my imx8 Mini board then
It gives me an error saying -

fatal error: gst/gst.h: No such file or directory
#include <gst/gst.h>

Can you suggest to me the steps to cross-compile the GStreamer for iMX Yocto ???

Thanks,
Maneesh

Hi @igorpadykov,

Any suggestions on how can I cross-compile GStreamer for iMX8 Mini yocto ?

The default GStreamer provided in iMX yocto BSP only supports the command line it does not support GStreamer C code hence I need to cross-compile the gstremer for iMX8M Mini Yocto.

I tried adding the following lines in iMX yocto local.conf file ->

IMAGE_INSTALL_append += "gstreamer1.0-rtsp-server gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav"

LICENSE_FLAGS_WHITELIST = "commercial"

But seems like GStreamer cross-compilation is not working because when I try to compile a simple GStreamer hello world application on my imx8 Mini board then
It gives me an error saying -

fatal error: gst/gst.h: No such file or directory
#include <gst/gst.h>

So any suggestion or step on how I can cross-compile the GStreamer for iMX Yocto?

Thanks

may be suggested to post it on meta-fsl-arm mailing list, as this is general yocto issue

Hi @igorpadykov

Thanks for your reply.

I will post it on https://lists.yoctoproject.org/g/meta-freescale

But can you tell me if I am doing the right changes or not?

To build GStreamer I am adding the following lines in iMX yocto local.conf file ->

IMAGE_INSTALL_append += "gstreamer1.0-rtsp-server gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav"

Am I doing correctly? or do I need to do changes in any other files also?

Thanks

one can look at nxp imx-gst1.0-plugins

https://source.codeaurora.org/external/imx/imx-gst1.0-plugin/tree/meson.build?h=MM_04.06.03_2110_L5.10.y

Hi @igorpadykov ,

As suggested by you I posted my query on meta-freescale@lists.yoctoproject.org

group, unfortunately, I didn't receive any response from there.

Can you help me with how can I cross-compile the gstremer library for iMX8M Mini EVK.

Thanks
