Hi! I'm trying to create a virtual camera with some effects and I'm not able to do it.
I've been trying to create a new device as a normal user and as a root admin.
As a Normal user, it returns "Wrong Password", and as root, it "creates" it but there's no print of it in /dev/.
Tryed compiling it myself and this was the answer

~/webcamoid-7.2.0$ dpkg-buildpackage -us -uc
tail: no se puede abrir 'debian/changelog' para lectura: No existe el archivo o el directorio
dpkg-buildpackage: fallo: final de «debian/changelog» devolvió un estado de salida de error 1

as some kind of non existing file debian/changelog

I don't know much about compiling my own software, but I read there is a way to set Root Method on .conf file. How do I do that? On Webcamoid.conf file there is no ROOT_METHOD entry.
Any guide?

It is just a minor issue. Still I have be declined at https://build.opensuse.org/request/show/138822 because of it: There is something wrong with the quotes in the .desktop file. Also there should be no absolute pathes in .desktop files. The desktop groups were invalid, too. I had to replace them with http://en.opensuse.org/openSUSE:Packaging_desktop_menu_categories because there are some strict checks maybe because of LSB compliance.

Hello,
When a video is played for a virtual webcam, ffmpeg creates multiple decoding/encoding streams depending on number of CU cores.

If to do
$ ffmpeg -re -i 40min.mp4 -f v4l2 /dev/video1 -f alsa default
(after modprobbing v4l2loopback which is used by Webcamoid)
then the CPU usage is low and it is not multistream.

Webcams are normally used with other video applications which also require quite a lot of system resources.

After I had compiled using those commands:

qmake-qt4 Webcamoid.pro #USE3DPARTYLIBS=1
make
su -c 'make INSTALL_ROOT=/usr install'
kbuildsycoca4

An executable file was generated webcamoid
But when I try to execute the file using '$ ./webcamoid' it doesn't work and I get this respond.

Hi,

I am packaging the last release for Debian and doing a final
test. To see Webcamoid running. As I did that on a VM (KVM),
I do not really have a webcam. But it is good to see the window
popping up, without a image, but the program is running. The
dependencies are ok.

If I run Webcamoid from Gnome Shell, I have only a blank
window. From a terminal I got this message:

'QFileSystemWatcher::addPAths: list is empty'

Two files has :
"libAvKys/Plugins/VideoCApture/src/v4l2/(capture|cameraout).cpp"

...QFileSystemWatcher(QStringList() << "/dev", this)

To see the behavior of other webcam application, I ran 'cheese'.
A blank window again. But with a message that tell something like:

"Not device found"

It is clear that the program ran fine and the webcam is missing. And
it was not necessary run the program from a terminal.

Can we have that on Webcamoid ?

regards,

This issue happens when recording audio from source, when switching from a source that provides an audio stream to a source that doesn't have an audio stream, the audio is no propertly recorded.

Hi,

Someone having problems with root password when trying to '+add' a device ?

When MultiSrc(source) is stopped, MultiSink(record) y stopped.

Qt 5.5 will require a few more includes, in this case QDataStream
This patch fixes the build with Qt 5.5rc:

Despite what I previously said, Webcamoid compiling went smoothly with Bison version older than 2.7 (2.5+).
Is there a minimum version of Bison (and Flex) to compile Webcamoid?

Hi,

The files on Build-Depends field are -ffmpeg-.

I believe the -ffmpeg- part should be removed. The result of a search
with apt-cache search (sid):

apt-cache search libavdevice

libavdevice-dev - FFmpeg library for handling input and output devices - development files
libavdevice-ffmpeg56 - FFmpeg library for handling input and output devices - runtime files

Hi,

VirtualCamera plugin is GPL-incompatible[0].

[0] - https://en.wikipedia.org/wiki/Shared_source#Microsoft_Limited_Public_License_.28Ms-LPL.29

I can not put a file with Ms-LPL license in Debian. I removed
the directory, edited Plugins.pro, tried "COMPILE_VCAM_DRIVER=0".
The package builds, but it does not work.

I click on 'Play' but no image at all. The error message:

$ LANG=C webcamoid
Error loading plugin "VirtualCamera" : "The shared library was not found."
"Error: Element 'VirtualCamera' doesn't exist."

VirtualCamera is for Windows only. What do I have to
do to disable it ?

regards,
Herbert

This is annoying to get webcamoid on gentoo.

It is possible to use Travis to build, test and upload packages for Ubuntu. Just an idea.
http://docs.travis-ci.com/user/uploading-artifacts/

On Ubuntu 16.04, Webcamoid will not start due to a missing dependency. Installing the package "libqt5qml-graphicaleffects" will allow the application to start.

Using 6.2.0.

It would be great if one could set a timer (e.g. 5 s) before the acutal photo is taken

Hi,

The webcamoid Debian package was uploaded
and is at NEW.

Let's see what the ftp-master will do now.

Can I use webcamoid to stream my desktop through videocall services like Skype or Google Hangouts? Because I already have tried using virtual webcam without luck.
Thanks in advance!

I succesfully build 6.2.0 on openSUSE 42.1.
However, ldd on the binary gave me a 'libQb.so.6 => not found'.

So - libQb is not needed to build - but to execute the program. Therefore it should be listed as a dependency in the documentation https://github.com/hipersayanX/webcamoid/wiki/Raw-build-and-install
, or not?

Hi,

I'm working on a debian package for webcamoid be part of Debian repositories.

There is a missing dependence in debian/control file: qtdeclarative5-dev.

I will report a few more things.

regards,
Herbert

Reduce the number of effects to show, and reduce the number of effects to apply.

The user said that he fixed the problem with qml-module-qtquick-dialogs package.
I installed the package but the errors still happen.

Webcamoid was builded with qtdeclarative5-dev. (log - i386)
https://buildd.debian.org/status/fetch.php?pkg=webcamoid&arch=i386&ver=7.0.0-2&stamp=1458754915

Do you have something in mind ?

I have the libavdevice-dev installed. And also libavdevice-ffmpeg56.

What files does it is searching for ? I have these:
https://packages.debian.org/sid/amd64/libavdevice-dev/filelist

Hi,

I would like to ask some things.

Can you remove the debian directory from the tarball ?
If is important to keep it in the repository, can it be in a
different branch ?

The binary webcamoid needs a manpage. I will do one,
but feel free to do if you want.

regards,
Herbert

Hi,

From the normal tool (debuild) the package is builded. But using
'cowbuilder', to test deps and all, it fails to complete the process.

There is the error message:
In file included from include/videodisplay.h:27:0,
from src/main.cpp:29:
include/videoframe.h:25:22: fatal error: QGLContext: No such file or directory
compilation terminated.

A quick search:
grep -r QGLContext /home/webcamoid/webcamoid-6.2.0/
/home/webcamoid/webcamoid-6.2.0/src/videoframe.cpp: QGLContext *context = const_cast<QGLContext *>(QGLContext::currentContext());
/home/webcamoid/webcamoid-6.2.0/src/videoframe.cpp: QGLContext *context = const_cast<QGLContext *>(QGLContext::currentContext());
/home/webcamoid/webcamoid-6.2.0/include/videoframe.h:#include

$ less /home/webcamoid/webcamoid-6.2.0/include/videoframe.h

include

include

Looking for QSGTexture:
$ grep -r QSGTexture /home/webcamoid/webcamoid-6.2.0/
/home/webcamoid/webcamoid-6.2.0/include/videoframe.h:#include
/home/webcamoid/webcamoid-6.2.0/include/videoframe.h:class VideoFrame: public QSGTexture

It seems to be something in the source code. Can't help more, sorry.

regards,
Herbert

My distro is Arch Linux (x86_64).
Ffmpeg version 2.0, I think that is the issue,
BTW: The PKGBUILD that is in your git repo doesn't works as it doesn't has
PREFIX=/usr while running qmake.

Theora encodes the video with very low bitrate (200k).

In some distributions, users are accustomed to do without PulseAudio.
Possible build options:
USE_PULSEAUDIO: 0, 1; default: 0

Fix recording.

Hi,

Another package in Debian provide a file with the same name
in the same directory. And webcamoid is newer.

/usr/lib/x86_64-linux-gnu/libqb.so

The chat can be read here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=809764

The file can be put in another directory when packaging but,
as said, will be a maintenance burden. The name of the file
can be changed ?

regards,
Herbert

Hi,

Webcamoid "fails to build with the upcoming version
of ffmpeg, which is planned to be released this month
(and will be called 2.9 or 3.0)" in Debian.

Original email:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=810558

Attached the patch file I used to build the debian package (6.2.0).

Uploading webcamoid_ffmpeg-2.9.patch.zip…

regards,
Herbert

MultiSink records a few seconds of a choppy sound.

Anyone doing real audio stuff on Linux uses JACK as it's much more flexible. Webcamoid appears to only support Pulse Audio. It should add direct ALSA support and full JACK support as options.

MultiSink doesn't saves the last a/v frames when recording is finished.
