GStreamer with VPU support on i.MX 8M Mini EVK

[mattia_dalben]

Hi,

I'm trying to build an image with yocto which support gstreamer with vpu plugins (I need the h264 hardware encoder). I added the following to my local.conf:

IMAGE_INSTALL_append = " gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav imx-vpuwrap imx-gst1.0-plugins"
LICENSE_FLAGS_WHITELIST = "commercial"

The starting point for my build is the "NXP eIQ Machine Learning Software Development Environment for i.MX Applications Processors" document (see attached).

But I get the following error:

$ bitbake fsl-image-qt5
WARNING: You have included the meta-virtualization layer, but 'virtualization' has not been enabled in your DISTRO_FEATURES. Some bbappend files may not take effect. See the meta-virtualization README for details on enabling virtualization support.

How can I fix this?

Hi Mattia

may be recommended to follow Yocto Guide (sect.5.1 Build configurations,

sect.5.2 Choosing an i.MX Yocto project image) included 

in official Linux documentation Linux 4.19.35_1.1.0 Documentation

i.MX Software and Development Tools | NXP 

Best regards

Hi Igor,

thanks for the quick answer but this doesn't solve my problem. I can already build an image successfully, I wanted to add the GStreamer plugin to leverage the VPU for h264 hardware encoding.

As I said the problem is related to:

ERROR: Nothing RPROVIDES 'imx-gst1.0-plugins' (but /media/mattia/HD500GB/NXPeIQiMX8MMMini/fsl-arm-yocto-bsp/sources/meta-fsl-bsp-release/imx/meta-sdk/dynamic-layers/qt5-layer/recipes-fsl/images/fsl-image-qt5.bb RDEPENDS on or otherwise requires it)

Which layer provides imx-gst1.0-plugins which contains the VPU accelerated GStreamer plugins?

[igorpadykov]

from sect.2 Features attached Yocto Guide:

"Multimedia recipes
• Multimedia recipes reside in recipes-multimedia.
• Recipes include imx-codec, imx-parser, libvpuwrap, and imx-gstreamer-plugins that pull from the i.MX mirror to
build and package into image recipes."

recipes-multimedia\meta-bsp\imx - meta-fsl-bsp-release - i.MX Yocto Project Release Layer

I've added the layer in the bblayers.conf file as follows:

LCONF_VERSION = "7"

BBPATH = "${TOPDIR}"
BSPDIR := "${@os.path.abspath(os.path.dirname(d.getVar('FILE', True)) + '/../..')}"

BBFILES ?= ""
BBLAYERS = " \
${BSPDIR}/sources/poky/meta \
${BSPDIR}/sources/poky/meta-poky \
\
${BSPDIR}/sources/meta-openembedded/meta-oe \
${BSPDIR}/sources/meta-openembedded/meta-multimedia \
\
${BSPDIR}/sources/meta-freescale \
${BSPDIR}/sources/meta-freescale-3rdparty \
${BSPDIR}/sources/meta-freescale-distro \
"

# i.MX Yocto Project Release layers
BBLAYERS += " ${BSPDIR}/sources/meta-fsl-bsp-release/imx/meta-bsp "
BBLAYERS += " ${BSPDIR}/sources/meta-fsl-bsp-release/imx/meta-sdk "

BBLAYERS += " ${BSPDIR}/sources/meta-browser "
BBLAYERS += " ${BSPDIR}/sources/meta-openembedded/meta-gnome "
BBLAYERS += " ${BSPDIR}/sources/meta-openembedded/meta-networking "
BBLAYERS += " ${BSPDIR}/sources/meta-openembedded/meta-python "
BBLAYERS += " ${BSPDIR}/sources/meta-openembedded/meta-filesystems "
BBLAYERS += " ${BSPDIR}/sources/meta-qt5 "
BBLAYERS += " ${BSPDIR}/sources/meta-virtualization "

But the error keeps showing:

ERROR: Nothing RPROVIDES 'imx-gst1.0-plugins' (but /media/mattia/HD500GB/NXPeIQiMX8MMMini/fsl-arm-yocto-bsp/sources/meta-fsl-bsp-release/imx/meta-sdk/dynamic-layers/qt5-layer/recipes-fsl/images/fsl-image-qt5.bb RDEPENDS on or otherwise requires it)

[igorpadykov]

imx-gst1.0-plugin_4.4.6.bb\gstreamer\recipes-multimedia\meta-bsp\imx - meta-fsl-bsp-release - i.MX Y... 

suggest to build image as described in Yocto Guide:

image "imx-image-multimedia" described in Table 1. i.MX Yocto project images,

machine configuration as "imx8mmevk" described in sect.5.1 Build configurations
