IPU6 daemon+v4l2loopback is required to enable use for existing applications

[Stefan]

The device is properly detected but it seems there are still issues with gstreamer plugin. When I try to run cheese I get the following error message:

../src/intel/isl/isl.c:2018: FINISHME: ../src/intel/isl/isl.c:isl_surf_supports_ccs: CCS for 3D textures is disabled, but a workaround is available.

(cheese:3769): cheese-WARNING **: 08:02:37.506: Failed to allocate required memory.: gstv4l2src.c(660): gst_v4l2src_decide_allocation (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin18/GstV4l2Src:v4l2src1:
Buffer pool activation failed

With VLC I get

Hi, could you do:

  $ sudo ln -s source_linux.py /usr/share/apport/package-hooks/source_linux-oem-5.13.py
  $ sudo apport-collect 1943915

The first command will manually create package hook link for source package linux-oem-5.13 as it should be (but missed in the official deb). Then it will collect as much info as needed generally for kernel issues.

I'll also need your output for following commands:

  $ apt-cache policy v4l2-relayd libipu6 libcamhal0
  $ cat /etc/default/v4l2-relayd
  $ cat /etc/v4l2-relayd

I did apport-collect, the information should now be attached to the bug.

As for the second part I don't have these packages installed and I
don't have the v4l2-relayd files either.

I have installed the missing packages from:

It looks like the gst-plugins-icamera failed to build:
https://launchpad.net/~oem-solutions-group/+archive/ubuntu/intel-ipu6/+build/21995982

[Stefan (polisholsby)]

I needed to install libdrm-dev when trying to locally compile gst-plugins-icamera even with libdrm-dev installed the compilation fails with:

I have managed to compile the GST plugin locally from:
https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api
after reverting:
https://github.com/intel/icamerasrc/commit/329ec92139f26594a00681c2a048c31c3de498d8

[Stefan (polisholsby)]

I have managed to compile locally from:
https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api
and got the camera to work with gst-launch-1.0
sudo -E gst-launch-1.0 icamerasrc device-name=ov01a1s-uf ! video/x-raw,format=YUY2,width=1280,height=720 ! videoconvert ! xvimagesink

Note: I need to run this command with sudo.

I have no idea what's required to get cheese and ffplay and other application to work properly.

[You-Sheng Yang (vicamo)]

I think you should be able to install following packages from the same ppa:

  * gstreamer1.0-icamera
  * v4l2loopback-dkms
  * v4l2-relayd

These 3 should be sufficient for you to bring up IPU6. And you'll need to create a config file /etc/v4l2-relayd:

  root$ echo <<EOF | tee /etc/v4l2-relayd
  VIDEOSRC=icamerasrc
  FORMAT=YUY2
  WIDTH=1280
  HEIGHT=720
  FRAMERATE=30/1
  CARD_LABEL=Intel MIPI Camera
  EOF

[Stefan (polisholsby)]

Yes, after installing these packages and adding the v4l2 relay config the camera works with ffplay and in firefox,not in cheese though, it still complains about:
"Buffer pool activation failed"
