libcamera is already in meta-multimedia layer, please update those recipes instead. meta-raspberrypi is not right destination for this but if there is anything thats RPI specific we can apply it via bbappends.

maurosanjo · 2021-11-29T19:14:07Z

Yes you're right, but current libcamera-apps is incompatible with the older version present in meta-multimedia, that's why i added it here, but can make a PR for meta-multimedia in openembedded, not sure though, since this repo has no tags to state stable versions yet.

libcamera-apps is the new alternative to userland made by raspberry, this might be useful here no?

is libcamera-apps specific to rpi ? or they just need libcamera in that case they are generic

agherzan · 2021-11-29T20:17:00Z

@maurosanjo We had a short chat today about this. Didn't we agree that we should start by uprev-ing meta-multimedia and add apps support as well?

maurosanjo · 2021-11-30T10:40:02Z

@agherzan Yeap, I misunderstood, doing a PR for meta-multimedia.

@kraj the repo states libcamera-apps are apps to mimic raspicam old functionality (userland), but as it uses libcamera it might work with other cameras :)

If you think raspberry/libcamera-apps recipe should be a part of meta-raspberry it should be inside recipes-multimedia ?

kraj · 2021-11-30T15:55:26Z

It’s suitable for meta-multimedia

shr-project · 2021-11-30T17:19:30Z

Just to link these PRs together, this is the libcamera update for meta-oe: openembedded/meta-openembedded#496

and there is another article documenting recent camera changes introduced with Bullseye:
https://www.raspberrypi.com/news/bullseye-camera-system/

this might also eventually replace old raspicam-node in ROS which was available only for 32bit rpi, because of dependency on MMAL from userland (which was available only for 32bit - at least back then, I haven't checked recently):

removed libcamera from this PR. libcamera-apps will be totally focused on raspberry environment and maintained inside Raspberry organization, so I believe it should not be outside of this meta-raspberry scope, what do you guys think?

that seems to be ok to have them here I guess.

Can you also please rebase/squash everything into one commit that has the common git log format (https://meta-raspberrypi.readthedocs.io/en/latest/contributing.html#formatting-patches).

Clean up this comment.

Remove it you mean?
Letting user know options to bbapend and customize the build makes sense as a comment?

I'm not sure what this is all about. Could you explain what did you mean by this comment block?

This are cmake options for libcamera-apps, that are documented here:
https://www.raspberrypi.com/documentation/accessories/camera.html#building-libcamera-apps

We can check automatically for this options, if opencv, tensorflow, qt, x11 are present, and -DENABLE_COMPILE_FLAGS_FOR_TARGET=armv8-neon when building for Pi 3 and Pi 4 in 32 bit.

That's what we should do. Based on distro features.

maurosanjo · 2021-12-06T15:35:22Z

Ops, when rebasing and squashing i did something wrong.

Updated the libcamera-apps commit source because newest version of libcamera would crash the build. Also tried to add changes requested by @agherzan , I'm still finding my way around yocto, so please check if this will do.

agherzan

Please also:

rename the recipe to rpi-libcamera-apps_git.bb. This fixes the version in this way and it is clear that the component is from RPI foundation.
squash all commits - the PR should have one and only one commit given what your content is: libcamera-apps: Add recipe for raspberry camera apps

+
+DEPENDS = "libcamera opencv boost libjpeg-turbo libexif tiff"
+RDEPENDS:${PN} = "libcamera opencv boost libjpeg-turbo libexif tiff python3-core"


Do we need these RDEPENDS? The packaging should be able to infer them without having them explicit. Any issues with that?

There is no such version as far as I can see. I don't see any 1.0 tags in the repo. Just use git in the recipe filename.

Can we have the explicit disable as well for all these PACKAGECONFIG entries?
eg: PACKAGECONFIG[qt] = "-DENABLE_QT=1, -DENABLE_QT=0"

This would be nicer to handle as a PACKAGECONFIG. And you enable it by default for the right DISTRO_FEATURES match.

This should be in by default hence not needed.

We can remove this and all the following using SOLIBS = ".so". I assume the package provides unversioned libraries only.

Hello,

libcamera and libcamera-apps are making a lot of important, and also breaking, changes on last commits. Now the recipe in openembedded for libcamera is no longer compatible with this layer due to meson build options that do not enable raspberry pi libcamera pipelines and ipas.
Take a look here:
openembedded/meta-openembedded@ea6d967

we need to add raspberrypi to -Dpipelines and -Dipas for it to work properly. This should be done inside meta-raspberry pi as a custom recipe for libcamera right?

Indeed. That sounds like a bbappend here.

Hi @maurosanjo. Any updates on this? I'm tempted to close the MR but it would be a bit of a waste unless you are not onto it anymore.
