Usb tether of camera does not work to flatpak Darktable

Firstyear commented 6 years ago

Hi there,

I've been really enjoying the Darktable flatpak you provide. Thanks for the great work to make it work so nicely.

Sadly I noticed that when I connected a camera via USB that should be supported for live view / capture (fujifilm xt-10) it did not display in the application.

I am aware that flatpaks do have a set of system isolation capabilities and wonder if this is related to the issue. Is there a way to enable usb tether support for the flatpaked darktable?

Thank you!

flatpak run --device=all org.darktable.Darktable

Does not seem to resolve the issue :(

Unfortunately, I cannot test this because I do not use USB tethering. But as far as I can tell it might or might not not only be a permission problem but also a missing dependency to libgphoto2. I added that now, so please check again if you can use tethering.

Great! I'll try this out as soon as I can. Thank you!

Okay tried this out. I think this would work now, but it looks like on further inspection my camera is not supported by gphoto 2 :(

I'll follow this up with the gphoto2 developers, and hopefully in a future update this will work.

Feel free to close this, and again, thanks for the quick update :)

Alright, feel free to re-open this issue if it is resolved by gphoto2 but not working with the flatpak.

I tried it today, did not work, even with --device=all. Unfortunately I don’t have the camera anymore.

jurf commented 6 years ago

Could someone reopen this please?

Hi, I'm writing an application for my own, utilizing libgphoto2 and flatpak as well. It didn't work initially, and on my quest to make it work I searched a lot and finally found out that libgphoto2 needs libusb as dependency. Have a look at this: https://gitlab.gnome.org/GNOME/shotwell/blob/master/flatpak/org.gnome.Shotwell.json

For debugging purposes I also added gphoto2, it looks like this for me now:

        {
            "name": "libusb",
            "sources" : [
                {
                "type" : "archive",
                "url" : "https://github.com/libusb/libusb/releases/download/v1.0.22/libusb-1.0.22.tar.bz2",
                "sha256" : "75aeb9d59a4fdb800d329a545c2e6799f732362193b465ea198f2aa275518157"
                }
            ],
            "config-opts" : ["--disable-udev"]
        },
        {
            "name": "libgphoto2",
            "sources": [
                {
                    "type": "archive",
                    "url": "https://downloads.sourceforge.net/project/gphoto/libgphoto/2.5.19/libgphoto2-2.5.19.tar.bz2",
                    "sha256": "62523e52e3b8542301e072635b518387f2bd0948347775cf10cb2da9a6612c63"
                }
            ]
        },
        {
            "name": "gphoto2",
            "sources": [
                {
                    "type": "archive",
                    "url": "https://netcologne.dl.sourceforge.net/project/gphoto/gphoto/2.5.17/gphoto2-2.5.17.tar.bz2",
                    "sha256": "aa571039240c68a053be710ca41645aed0239fa2f0b737b8ec767fef29e3544f"
                }
            ]
        },

And now you can check whether libgphoto2 finds your camera inside the flatpak container like this:

me@mycomputer$ flatpak run --command=sh org.gnome.My_Fancy_App
sh-4.3$ gphoto2 --auto-detect
Modell                         Port                                            
----------------------------------------------------------
Sony Alpha-A77 M2 (Control)    usb:001,007     
sh-4.3$

Just wanted to let you know about this as I find it very cumberstone to find decent information about specific dependencies in flatpak containers. Haven't tried it in your case, but maybe it fixes the issue.

we need to add libusb to the flatpak. otherwise libgphoto2 is built without USB support.

hfiguiere commented 5 years ago

As mentioned in the PR, --device=all is needed with the patch above. But at least USB support is there.

hfiguiere commented 5 years ago

It will be added by default so that USB works out of the box.

hfiguiere commented 5 years ago

Fixed in the latest flatpak
