Description Pascal Flöschel 2021-09-14 12:58:23 UTC
wireplumber configuration expects pipewire built with v4l else it fails with the following error:

systemd[1108]: Started Multimedia Service Session Manager.
Sep 14 13:07:46 gentoo wireplumber[213275]: SPA handle 'api.v4l2.enum.udev' could not be loaded; is it installed?
Sep 14 13:07:46 gentoo wireplumber[213275]: wplua_pushobject: assertion 'G_IS_OBJECT (object)' failed
Sep 14 13:07:46 gentoo wireplumber[213275]: Runtime error while loading 'v4l2.lua'
Sep 14 13:07:46 gentoo wireplumber[213275]: [string "v4l2.lua"]:134: attempt to call a nil value (method 'connect')
                                            stack traceback:
                                                    [string "v4l2.lua"]:134: in local 'chunk'
                                                    [string "sandbox.lua"]:95: in function 'sandbox'
Sep 14 13:07:46 gentoo wireplumber[213275]: disconnected from pipewire
Sep 14 13:07:46 gentoo systemd[1108]: wireplumber.service: Main process exited, code=exited, status=70/SOFTWARE
Sep 14 13:07:46 gentoo systemd[1108]: wireplumber.service: Failed with result 'exit-code'.


Reproducible: Always

Steps to Reproduce:
1. build media-video/pipewire "-v4l"
2. start media-video/wireplumber: start fails
3. 
Actual Results:  
wireplumber fails to start

Expected Results:  
wireplumber starts

seems a configuration problem that can be mitigated by v4l use flag in pipewire
Comment 1 Niklāvs Koļesņikovs 2021-09-15 09:55:07 UTC
Thank you for noticing and reporting this. This should get fixed upstream soon enough (famous last words?) and we'll backport the fixes then if there's no imminent release in sight. For better or worse there's already open PR for a slight ebuild improvement/fix, so that can be reused if it's still unmerged by then.

    media-video/wireplumber: fix errors on missing BlueZ and V4L
    
    Two of the commits have not yet been accepted upstream but they
    were prepared with the help of upstream and should be in acceptably
    good quality to use until a fixed release is made.
