Hi Jules, a year ago I developed a workaround for running videoconference using the iOS port, I remember I get green frames when receiving the video during the first tests. First of all, be sure you are receiving RTP packets in the receiver endpoint. Check the image color space conversion when sending the frames, I did it by using simple and very fast memcpy operations. I recommend you to send allways the same frame from a local image (in CIF, QCIF or the size you need) in your resources bundle instead of trying to send the frames retrieved from the AVFoundation API. Also I recommend you to use first the h263 codec implementation included in the ffmpeg, but its just a recomendation for making your tests more easy. Luck!
