Abstrak—Video streaming has become one of multimedia
applications that streams video over network, both internet network
and local network. Real-time multimedia data transmission in
the multimedia application requires video compression to exploit
limited storage capacity and to use bandwith as efficient as possible.
Encoder and Decoder (Codec) are tools to compress video. This
final project proposes video compression thatto uses free licensed
Dirac Video Codec. Whereas Dirac player (a player that support
Dirac codec) was used to run Dirac-encoded. Utilization of graphics
processor (GPU) was used in order to assist computation and
to help reduce the computation time. In the experiment, three-
Dirac-encoded-video-streaming using Dirac player in a multicast
manner. The result was performed in one client computer, and
showed that there was maximum two video played with processor
usage of 60-70%. Beside that, the experiment also performed in
direct streaming from camera which has resolution 320x240 pixel
by using transcoding. From the third experiments (using camera)
Dirac transcoding showed 35% average use of bandwith compare
to H.264 transcoding, with nearly equal time delay, which is about
three second.
Kata Kunci—video streaming, Dirac Video Codec, processor
graphics, multicast.
