How does our software really work ?
How does our software sends video and audio between the users?!
AVChat and AVConference are Flash applications that when run in the browser they make a connection to a media server. Once the connection is made, video, audio and text data can be sent over this connection in real time. The video, audio and text data travel from the broadcaster to the media server and from there to the reciever (hopefully in less than 200ms :D ).
The media server software can be installed on a dedicated server. If you do not have a dedicated server at hand you can get media server hosting for as low as $6/month from influxis.com.
How about the quality of the video and audio?!
With our software you can control every aspect of the audio and video quality: resolution, maximum bandwidth, picture quality, frames per second, key frames per second and the sound rate (sound quality).
During a video chat or video recording session Flash Player grabs the video data from the webcam, encodes it using the Sorenson h.263 video codec, grabs the audio from the microphone, encodes it using the NellyMoser audio codec and then it sends all this data to the media server.
More about Flash audio and video codecs...
Flash Player can only use the Sorenson h.263 codec to ENCODE the video data and send it to a media server. For ENCODING audio, 2 codecs can be used: the older NellyMoser and the newer Speex.
Desktop tools like Adobe's Flash Media Live Encoder and On2's Flix Live can encode audio and video using much better/advanced codecs like vp6 and h.264 for video and aac or mp3 for audio.
