|Abstract: ||Nowadays, smartphone is a very common communication tool, 8 out of 10 people
are having a smartphone instead of a normal mobile, a smartphone does not only
provide basic communication function but also some media and entertaining
applications. One of the media function is the video recording, people can record
their life and share with their friend later. However, it is time-consuming for your
friend to wait for your video upload. So this project is going to implement a real-time
video sharing application for your friend to watch your video in real time.
Nonetheless, one of the bottlenecks of real time video streaming is the bandwidth.
For mobile users, although 3G is very common nowadays and the transmission rate is
much better than 2G but the speed is still never guaranteed and fluctuates all the
time according to different area and number of user with the same network provider.
If non-compressed video is sent over low bandwidth network, it will cause the
problem of delay and lag, as a result the user cannot enjoy a smooth video. To tackle
it, some methods are needed to reduce the size of the video according to the
In this project, it will demonstrate an unstable network with fluctuated bandwidth.
And auto detection on the bandwidth status is used to manipulate the frame size of
the video (i.e. reduce the frame size under low bandwidth). Besides, the users can
also make use of the mix quality video function to optimize the quality of a specific
part of the video and current bandwidth.
And for the streaming protocol, the Real-time Transport Protocol (RTP) is used for
transmission, it is a protocol for audio and video delivering over IP network. The
video frame will pack as a RTP packet and send from the client to server.|
