- W630528036 abstract "This project is about implementing and evaluating the WebRTC library for its suitability in enabling mobile video conversations on the iOS operating system. Two video codecs and two protection techniques from the library were evaluated for their effectiveness in providing a good video quality in the conversation. These codecs are called I420 and VP8, and the techniques are called negative acknowledgment (NACK) and forward error correction (FEC). NACK turned out to perform best when the delay in the network is low, and the FEC performed best when there is plenty of available bandwidth. VP8 turned out to be most suitable video codec to use in mobile environment due to its low bandwidth requirements.An improvement to the FEC technique that changes how the packets are protected, called unequal error protection (UEP), was also implemented and evaluated. The unequal error protection did only provide a minimal improvement in performance, but some suggestions are made on how the technique could be further improved." @default.
