When video is enabled in ekiga 2.0.5, the performance issue became critical especially with 2x view of local and remote video. The CPU used percentage of ekiga is higher than that in linux(opensuse). By now reducing the scale and copy times on gdkpixbuf is a way. Another thing can be done is to add compile option to get optimized binary. Meantime medialib2.5 is used to get fast color conversion of YUV420PtoRGB.
