I have built a custom qt5-image with Yocto on my Raspberry Pi 4 - 64 8GB box.
It also builds gstreamer 1.20.3.
At first, I didn't have the video4linux2 plugins installed.
So I rebuilt gst-plugins-good and gst-plugins-bad with related options:
-Dv4l2=enabled -Dv4l2_codecs=enabled...
The build succeeded.
But on the target board the gst-inspect-1.0 video4linux2 only outputs 4 plugins:
- v4l2src
- v4l2sink
- v4l2device...
- ...< forgot the name>
I'm atually looking forward the v4l2h264dec. I don't have it and I don't really understand why it's not there whereas the yocto recipes have all succeeded.
I guess there's driver issue ?
I have also noticed that I don't have any /dev/videoxxx file descriptor. Is that normal ?
Should I setup something in the kernel options ?
I have also read that on 64 bits rpi4 boards,v4l2_m2m shall be considered.
