Linphone

Postby dirigible » 27 Jul 2015 09:13

Installed Linphone from the Solyd repos and the self-view feature doesn’t work.
The LED on my Logitech HD 720p usb webcam illuminates when I enable self-view but no picture, just a black screen.
This webcam works with other programs.
From the Googling I’ve done it seems to be a common problem in version 3.6.1 unless it's compiled with "--disable-glx".

I'm wondering if anyone is successfully using it at the moment?

I'm running KDE 64bit.

dirigible: I run Linphone 3.6.1 on 32-bit SolydX and my logitech camera works fine on self-view. This is just the standard repo deb package - no compiling required. My multimedia settings are as follows (scroll down for video):

It may be necessary to change the video input device and resolution settings to suit your system.

I know you said that your webcam works with other programs but I like to do a quick check with VLC:
Open VLC then menu Media > Open Capture Device > Set Capture Mode to Video Camera. Set Video device name as required (e.g. /dev/video0). Then hit "Play" button at the bottom to display your video camera output.

In my case, I can only have one application at a time accessing the camera. It might be worth checking that you do not have another video application using the camera when Linphone is started.

Thanks Zill,

Worked with VLC.
Matched your settings in preferences but still just a black screen.
It may be a 64bit or KDE related issue that’s causing it.

Does anyone have this working in KDE and/or 64bit?

dirigible: These are the (relevant) packages installed on my system (from dpkg -l):

Code: Select all

ii  linphone                               3.6.1-2.4+b1             i386
ii  linphone-common                        3.6.1-2.4                all
ii  linphone-nogtk                         3.6.1-2.4+b1             i386

ii  liblinphone5:i386                      3.6.1-2.4+b1             i386

ii  libv4l-0:i386                          1.6.0-2                  i386
ii  libv4lconvert0:i386                    1.6.0-2                  i386
It may be possible that this issue relates to 32/64 bit compatibility so it might be worth taking a look at the multiarch documentation but I cannot help much with this as I have, so far, avoided this problem by sticking to 32-bit. :?

So whats the exact syntax for using dpkg -l to list only Linphone packages?

dirigible: Open a terminal then maximise it (otherwise some of the output doesn't show). Enter dpkg -l followed by the package of interest. You can add a wildcard (*) at the end if you want all possible variants. e.g.

Code: Select all

dpkg -l linphone*
dpkg -l liblinphone*
dpkg -l libv4l*
For more info see:

Code: Select all

man dpkg

Here's mine

Code: Select all

ii  linphone                  3.6.1-2.4+b1      amd64
ii  linphone-common           3.6.1-2.4         all
ii  linphone-nogtk            3.6.1-2.4+b1      amd64
ii  liblinphone5:amd64        3.6.1-2.4+b1      amd64
ii  libv4l-0:amd64              1.6.0-2            amd64
ii  libv4l-0:i386               1.6.0-2            i386
ii  libv4lconvert0:amd64        1.6.0-2            amd64
ii  libv4lconvert0:i386         1.6.0-2            i386
Nothing seems to be missing.
Perhaps version 3.7 will work.

Code: Select all

linphone --help
linphone -h
man linphone
what is the result of these commands? some program have hidden features which can only used if it executed from terminal. i'm not quite sure but linphone might have an option to disable glx. if those command shows nothing you can try this one

Code: Select all

linphone --disable-glx


anyway, if you're on stable you won't get linphone 3.7 for approx next two years. don't wait for it :3

Thanks for the suggestions but I still don't see a solution.
Being a cross platform application I thought it might be interesting to try.
I'll let it go for now. No big deal.

dirigible: Have you tried WebRTC as suggested here? ...

Gave Firefox Hello a try. My friend at the other end was using Firefox on a Windows laptop.
Video worked fine but there was no sound either way.
It's still in Beta. Looks promising so I'll try it again in 6 months or so.

dirigible: Could just be a configuration problem at one or both ends! You need to ensure you use the correct sound source for the microphone, such as the USB camera. Try playing around with the sound mixer settings (alsamixer from the terminal is good!) to make sure none of the mic channels are muted.

It is also worth trying the other WebRTC links I posted earlier - none require any registration or any other details.

I use often Firefox Hello for videocalls. It works very good.
