| jbpons | Hi all ! I comeback with my problem which I mentioned last week : https://irclogs.baserock.org/automotive/%23automotive.2020-10-08.log.html | 08:20 |
| jbpons | To sum up, I want to test the “camerabin” plugin of gstreamer with the command “gst-launch-1.0 camerabin”. This command return me the following message (there is no logs in journalctl) : https://framabin.org/p/?c7c283c27e40b37d#S5GyndU2RfzbdL/pKfHR/qdjLQqpCxowEN4/sypZA2o= | 08:20 |
| jbpons | Thanks to strace (https://framabin.org/p/?9906b999cd0fe242#lSuWSOFH1Em7Q4CC4ZZvGqtyyEwADMs2sSEYQQ0OW3E=) I found the source of the problem which seems to be a syscall connect : connect(28, {sa_family=AF_UNIX, sun_path="/run/user/0/pipewire-0"}, 25) = -1 ENOENT (No such file or directory) | 08:20 |
| jbpons | This syscall seems to try to access the pipewire-0 socket of the /run/user/0/ depository but this one is located in /run/user/1001/. | 08:21 |
| jbpons | Do you know how can I fix this ? | 08:21 |

| mvlad | jbpons: are you running it as agl-driver? | 09:59 |
| jbpons | Yes and I have the same issu : https://framabin.org/p/?ea64fadb73f7d8ba#rKO/4yU39iTwe7w2Obk0RPDO2QATCFrM/ykMCDdXuoE= | 10:08 |
| jbpons | strace gave me that : connect(23, {sa_family=AF_UNIX, sun_path="/run/user/0/pipewire-0"}, 25) = -1 EACCES (Permission denied) | 10:08 |
| jbpons | But I just find this with strace : openat(AT_FDCWD, "/dev/video0", O_RDWR|O_LARGEFILE) = -1 EACCES (Permission denied) | 10:09 |
| jbpons | It could be linked with what smurray told me last week about udev rules ? | 10:09 |
| mvlad | yes, for the video one for sure | 10:18 |
| *** anjumkaiser has quit IRC | 11:23 | |
| jbpons | Ok ! Thank you mvlad ! | 11:32 |

| jbpons | mvlad: I don't solve my issu with my "camerabin" gstreamer plugin but my Qt application finaly works. I think it works since the beginin but I have a very very low contrast that's why my viewfinder seemed all black. | 14:27 |
| jbpons | And for the udev rules : in meta-agl/meta-agl-profile-graphical/recipes-graphics/wayland/westin-init.bbappend there is a rule for add "display" group to the "videol4linux" | 14:29 |
| jbpons | This allows my app to read the /dev/video0 device | 14:30 |
| jbpons | mvlad: I have another little question : I have a touchscreen (connected to my RPI with a HDMI and a USB) and a mouse cursor is displayed. How can I disable it ? I tried to add the line "app.setOverrideCursor(QCursor(Qt::BlankCursor));" but it doesn't hide it. | 14:33 |
| jbpons | *add the line to all apps | 14:33 |
| smurray | might take something in weston.ini | 14:35 |

| mvlad | well, another option would be to compile it out from qt entirely. | 17:13 |
