Missing v4l2h264enc plugin on MX8QMEVK/Linux-4.19

[RobbieJiang]

SoC: MX8QMEVK

Yocto: warrior 4.19

root@imx8qmmek:/usr/lib/gstreamer-1.0# uname -a
Linux imx8qmmek 4.19.35+ #2 SMP PREEMPT Mon Oct 19 23:10:49 PDT 2020 aarch64 aarch64 aarch64 GNU/Linux

command to build image:

DISTRO=fsl-imx-xwayland MACHINE=imx8qmmek source fsl-setup-release.sh -b build-xwayland

bitbake imx-image-multimedia

The built library libgstvideo4linux2.so  has related sysmbols:

However, after flashing this rootfs image to the EV board:

root@imx8qmmek:/usr/lib/gstreamer-1.0# gst-inspect-1.0 | grep 264
videoparsersbad: h264parse: H.264 parser

uvch264: uvch264mjpgdemux: UVC H264 MJPG Demuxer
uvch264: uvch264src: UVC H264 Source

There is no v4l2h264enc / v4l2h264dec plugins.

How to build and install v4l2h264enc / v4l2h264dec plugins to MX8QM EVK rootfs?

Am I missing anything?

Hi RobbieJiang

one can try to follow sect.5.2 Choosing an i.MX Yocto project image (imx-image-multimedia,

imx-image-full) Yocto Guide included in Documentation

or test with Demo Image  i.MX 8QuadMax MEK

All documentation
