How to connect a webcam
-
If I connect a usb web cam to my Meizu Pro 5 UBports 15.04 edition, how can a view the image on my device screen?
I installed cheese but it does not run giving an error of not being able to connect to the Mir server.

Try using http://appear.in and see if the browser uses your additional cam too.

When I do a connect with some USB cam, in /var/log/syslog the following lines show up:

Linux' vlc would be my first guess on any desktop system with X11.

@guru Oh, when I connect my usb cam, the /var/log/syslog says "Device not responding to set address" and no new device is created in /dev/usb* ...
-
@mihael I have to admit, that this BQ E4.5 still runs the latest OTA of Canonical. The UBports BQ E4.5 I do have too, sits at home, I will try it later/tomorrow.
-
@guru Thank you for offering to help with this. I have a usb endoscope camera that I want to use and that is why I would like to view it on my phone.
-
maybe the media player app can be hacked into submission to show the camera rather than a file
https://github.com/ubports/mediaplayer-app/blob/master/src/mediaplayer.cpp#L128
that is, IF the device is setup by the OS
-
I have no idea which devices are my cams. There are so many /dev/video* ...
-
Btw: I have no /dev/vi* device at all, not in my BQ E4.5 running Canonical's UT, and not in the UBport's one.
I pluged today a cam into the latter and the result is the same:

Maybe QtMultimedia detects the webcam and you can use it from there? $ cat >cameras.qml <<EOT import QtQuick 2.4 import QtMultimedia 5.6 ListView { model: QtMultimedia.availableCameras delegate: Text { text: "id: " + modelData.id + ", name: " + modelData.displayName } } EOT $ cat >$HOME/.local/share/applications/cameras.desktop <<EOT [Desktop Entry] Name=Camera List Exec=qmlscene $HOME/cameras.qml Type=Application X-Ubuntu-Touch=true EOT Then refresh your app scope and start it from there and see if there are more than the two default cameras (front/back). My E4.5's output: id: undefined, name: Camera 0 Back facing id: undefined, name: Camera 1 Front facing Hope this helps.For the moment this is all. No
I followed the advice of Christoph, and it shows only the two mentioned cams (Back and Front).
