G2D problems during 'bitbake imx-image-multimedia' for IMX8QM/Yocto-4.19

[RobbieJiang]

We are trying to build imx-image-multimedia  with imx gstreamer plugins for MX8QM and Linux -4.19.45.

The yocto is 4.19-warrior.

First, we add following lines to 'local.conf':

IMAGE_INSTALL_append = " gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly imx-gpu -g2d imx-gpu-viv gstreamer1.0-plugins-imx imx-gst1.0-plugin "
LICENSE_FLAGS_WHITELIST = "commercial"

And run 'bitbake imx-image-multimedia':

Finally we got the following errors:

There are two 'virtual/libg2d' providers in the bitbake recipes :

sources/meta-freescale/recipes-graphics/imx-dpu-g2d/imx-dpu-g2d_1.4.8.bb

sources/meta-freescale/recipes-graphics/imx-gpu-g2d/imx-gpu-g2d_6.2.4.p1.8.bb

Both recipes include 'PROVIDES += "virtual/libg2d"

However,  'bitbake -c compile imx-gpu-g2d' failed.

How to fix this problem?

Hello Robbie,

Please move a supported kernel is based on 4.19.35 or 5.4.24 linux kernels, now the imx-gpu-g2d is not supported anymore you should try bitbake -c compile imx-dpu-g2d.

Hi,

Thanks for your reply.

I tried to remove 'imx-gpu-g2d' from local.conf.

However, there is still NO v4l2h264enc / vl42h264dec plugins on my MX8QM board 

root@imx8qmmek:~# gst-inspect-1.0 | grep h264
videoparsersbad: h264parse: H.264 parser
rtp: rtph264pay: RTP H264 payloader
rtp: rtph264depay: RTP H264 depayloader
uvch264: uvch264src: UVC H264 Source
uvch264: uvch264mjpgdemux: UVC H264 MJPG Demuxer
typefindfunctions: video/x-h264: h264, x264, 264

The rootfs is build by 'bitbake imx-image-multimedia',

and here is my local.conf:

MACHINE ??= 'imx8qmmek'
DISTRO ?= 'fsl-imx-xwayland'
PACKAGE_CLASSES ?= 'package_rpm'
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"

ACCEPT_FSL_EULA = "1"
IMAGE_INSTALL_append = " gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly imx-gpu-viv  imx-gst1.0-plugin "
LICENSE_FLAGS_WHITELIST = "commercial"

Anything wrong?

And how can I build and install v4l2h264enc / v4l2h264dec plugins on my MX8QM / yocto(4.19 warrior) system?

 Regards.

Hello ,

According to attached Release Notes p.36 for i.MX8QM v4l2h264enc

is used, not vpuenc_h264, like:

gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=300 io-mode=dmabuf ! \
'video/x-raw,format=(string)NV12,width=1920,height=1080,framerate=(fraction)30/1' ! \
queue ! v4l2h264enc output-io-mode=dmabuf-import ! \
avimux ! filesink location=test.avi
