How to find all ip cameras and get videos

SGaist

As indicated in that library's documentation, it's unmaintained. They have now a GStreamer plugin.

As I already wrote, on Linux, Qt uses GStreamer as backend.

Please tell me how to configure the .pro file? I did so, but which libraries should I connect?

INCLUDEPATH += /usr/include/gstreamer-1.0
INCLUDEPATH += /usr/include/glib-2.0
INCLUDEPATH += /usr/lib/x86_64-linux-gnu/glib-2.0/include
LIBS += -L/usr/lib -L /usr/lib/x86_64-linux-gnu -L/usr/local/lib -L/usr/lib/x86_64-linux-gnu/gstreamer-1.0

Mikeeeeee

Maybe you have examples of playing videos in a window using Gstreamer?

Mikeeeeee

I looked at the example and am trying to find this library:

LIBS += -L/usr/lib -L /usr/lib/x86_64-linux-gnu -L/usr/local/lib -L/usr/lib/x86_64-linux-gnu/gstreamer-1.0 -lgstvideo-1.0

and I get error:

cannot find -lgstvideo-1.0

but in the folder /usr/lib/x86_64-linux-gnu there is a file libgstvideo-1.0.so.0
How can I fix this?

SGaist

Did you install the GStreamer development package ?

Mikeeeeee

Yes, i do

SGaist

Which one ?

Which one ?

I have installed many gstreamer packages. All the necessary h files are there, and I also found the library manually.

SGaist

In that case you should also have the unnumbered .so file.

I have only libgstvideo-1.0.so.0.1405.0 . But I'm connecting -lgstvideo-1.0 . What other libraries should there be?

SGaist

What exact GStreamer development package did you install ?

Mikeeeeee

I do this:

apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

jsulm

@Mikeeeeee So, you did not install development packages (-dev)...

Mikeeeeee

Which package should I install with-dev? There is no such thing on the official website.
