Hello,

I'm trying to place video calls with linphone but with H263 I receive the following error:

linphonec> 2016-02-13 15:49:50:888 ortp-error-no such method on filter MSH263Enc, fid=16392 method index=8
2016-02-13 15:49:52:840 ortp-error-Camera is proposing a size bigger than encoder's suggested size (640x480 > 352x288) Using the camera size as fallback because cropping or resizing is not implemented for this device.
[h263 @ 0xb0291908] The specified picture size of 640x480 is not valid for the H.263 codec.
Valid sizes are 128x96, 176x144, 352x288, 704x576, and 1408x1152.Try H.263+.
2016-02-13 15:49:52:843 ortp-error-avcodec_open() failed: -1

I've tried to change size parameter in .linphonerc with qcif, cif, vga, 4cif but result is always the same. Is there any way to change video size for H263 codec?

With H264 video works, but quality is not satisfactory

anyone can help me?
