Re: [Linphone-users] Black screen when using video call

[Guillaume Beraudo]

Hi,

There is an issue with xv:
message: V4L2 video capture started.
message: x11video_prepare(): Window has size 352x288, received video is 352x288
error: Could not find suitable format or Xv port to work with.

There may also be an issue with the video codec:

I suggest that you compile linphone/mediastreamer/ortp 3.6.1 with opengl
and use vp8 codec.
