It appeared that xlovecam.com uses audio and video are on two separate streams (similar to adobe meeting):
Eg: rtmp://91.208.175.159/xlovecam_dev<break>audio_38378_1307410102513132
Eg: rtmp://91.208.175.159/xlovecam_dev<break>video_38378_1307410102513132

They also have a site specific security on it. It doesn't send RTMP audio/video or flv packets but instead sending packets of unknown type 131 (0x83). So currently I can only recommend to use screen video capture software.
