gstreamer rtsp server on "i.MX 8M Mni EVK"

[ysato_ad]

I want to implement gstreamer rtsp server on "i.MX 8M Mini EVK".

https://www.nxp.com/docs/en/user-guide/IMXLXYOCTOUG.pdf
I set up Yocto Project on the host machine while referring to the above.

Then, at https://www.nxp.com/docs/en/user-guide/IMXLUG.pdf
I did bitbake with reference to '7.3.14 RTSP streaming server',
But, there are no .libs, no builds directory.

Please tell me the cause and measures.
For the time being, I checked the following, but it did not work.
https://community.nxp.com/thread/380070

What I did:
1) $ cd imx-yocto-bsp

2) $ MACHINE=imx8mmevk DISTRO=fsl-imx-xwayland source ./fsl-setup-release.sh -b build

3) $ gedit ./conf/bblayers.conf &

Hi ysato.ad@minebeamitsumi.com ,

To build .libs/test-uri (to build examples and tests) remove or comment the below line from file gstreamer1.0-rtsp-server.inc (path: sources/poky/meta/recipes-multimedia/gstreamer/gstreamer1.0-rtsp-server.inc).

         EXTRA_OECONF = "--disable-examples --disable-tests"

then follow the steps from section 7.3.14 RTSP streaming server of i.MX Linux User's guide.

Let us know if you have any further query.

Regards,

Radhika Somaiya.

Hi Radhika Somaiya

Thank you for your reply.

Before seeing this reply, I tried the following and was able to confirm the operation.
But I was wondering why bitbake doesn't automatically make it.
I understand from your reply.

I tried the method you taught me.
It was automatically made with bitbake.
Thank you very much.

you can use this L4.14.98-2.0.0_ga, but core-image-minimal is the minimal image which only supports board booting up, try to use "fsl-image-qt5-validation-imx"

[ysato_ad]

Hi Joan Xie

Thank you for your reply.

I have verified that test-uri can be run on the target of L4.14.78_1.0.0_MX8MM.

Is L4.14.78_1.0.0_MX8MM that can be downloaded from the following URL bit-baked with "fsl-image-qt5-validation-imx"?

L4.14.78_1.0.0_MX8MM
https://www.nxp.com/webapp/sps/download/license.jsp?colCode=L4.14.78_1.0.0_MX8MM&appType=file1&DOWNL...

[joanxie]

yes, it should be built by "fsl-image-qt5-validation-imx", but since you need add your own feature in the bb file, I think you should build by yourself

[ysato_ad]

Hi Joan Xie

I was checking RTSP in the environment of 'L4.14.78_1.0.0_MX8MM' I wrote first.
I checked the writing of the image of 'core-image-minimal' that I created, and it was CUI.
Recreate the image with 'fsl-image-qt5-validation-imx'.

Thank you.

Hi ysato.ad@minebeamitsumi.com ,

As per the Yocto project User's guide, L4.9.88_2.0.0_ga is not supported for imx8mmevk so, Have you added the support of i.MX8M mini in rocko by yourself?

We are working on it with sumo L4.14.98_2.0.0.

Radhika Somaiya.

Hi Radhika Somaiya

Thank you for your reply.

Sorry.
I forgot to write my current environment.
https://source.codeaurora.org/external/imx/imx-manifest/tree/?h=imx-linux-sumo
I referred to the following URL and used 4.9.88-2.3.1.
> $ mkdir imx-yocto-bsp
> $ cd imx-yocto-bsp
> $ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.9.88-2.3.1.xml
> $ repo sync
