[Linphone-developers] Video view shows black window using Intel 945GM

[ichrispa]

Hello Linphone mailing list,

I have downloaded and compiled the latest GIT version of linphone on OpenSUSE 12.3 in order to enable Video support using H264 and v4l2. The codecs and video camera are correctly recognized, but both in self view as well as in transmissions only a black window is shown. The logs suggest that the video input is both received and parsed correctly, but displaying images fails (See Log excerpt beneath signature).

The webcam uses the uvcvideo driver and works under other applications The system uses an Intel 945GM Graphics Adapter (OpenGL 1.4). I suspect that there is either a problem with the video overlay or the missing OpenGL 2.0 support. When running linphonec -V I get the following error:

ortp-error-no such method on filter MSGLXVideo, fid=16387 method index=1
ortp-error-Need OpenGL 2.0+

Any help is highly appreciated,

Chris
