Building VPU and gstreamer using Yocto for IMX53

kravik — Thu, 24 Sep 2015 12:58:13 GMT

I have build images for imx53EVK board using yocto updated at https://community.freescale.com/message/570496#570496 and flashed images by referring https://community.freescale.com/message/528720#528720 .

When I flashed the u-boot built with yocto then board is not booting, but if I use prebuilt u-boot then board is booting.

Now I want to build VPU and gstreamer using Yocto.

I could see the following line in sources/Documentation/release-notes/source/issues-known.rst file inside yocto.

--------------------------------------------------------------------------------------------------------------

1. Fail to build imx-lib/imx-vpu/imx-test/gst-fsl-plugin when building against linux-fslc

--------------------------------------------------------------------------------------------------------------

Any one tried to build imx-vpu and gstreamer using yocto?

I thought of building vpu first. I could see following package entry in meta-fsl-arm/recipes-multimedia/libfslcodec/libfslcodec.inc file.

----------------------------------------------------------------------------------

PACKAGECONFIG[vpu] = "--enable-vpu,--disable-vpu,imx-vpu"

----------------------------------------------------------------------------------

I think it has to be enabled in the poky.conf(as the distribution is poky from local.conf). Can you please suggest me how to make an entry in poky.conf to enable vpu.

I started building gstreamer by adding following content in local.conf file.

IMAGE_INSTALL_append = "\

gstreamer \

gst-meta-base \

gst-plugins-bad \

gst-fsl-plugin"

It build successfully, but when I execute following command, it is giving "WARNING: erroneous pipeline: no element "aiurdemux"" error.

#gst-launch filesrc location=Avengers.mp4 typefind=true ! aiurdemux ! queue max-size-time=0 ! mfw_vpudecoder ! mfw_v4lsink

I thought the error related to "aiurdemux" may be related to absence of gst-ugly plugins, so I tried building gst-ugly plugins, but build is failing with following error.

----------------------------------------------------------------------------

Can you please help to fix the following error.

Please, take a loon in

FSL Community BSP Release Notes 1.8 documentation

and

FSL Community BSP

Are you subscribed to meta-freescale mailing list? Several important changes were included recently for mx53 and we discussed all them in meta-freescale. Maybe you can take a look on archives.

I was not able to understand which source code and branch are you using.
