Video Streaming-Video/MP3/Audio

There are many video file formats to choose from when creating video streams. The most common formats are:

1. Windows Media
2. RealMedia
3. Quicktime
4. MPEG (in particular MPEG-4)
5. Adobe Flash

There are pros and cons for each format but in the end it comes down to personal preference. Be aware that many of your users will have their own preferences and some users will only use a particular format, so if you want to reach the widest possible audience you should create separate files for each format. In reality this isn't usually practical so you need to make a judgment call on which formats to provide. Obviously the better you understand all the options, the better your decision is likely to be.

Streaming is a technology for playing audio and/or video files (either live or pre-recorded) directly from a server without having to download the file. This avoids time-consuming downloads of large files, and may help avoid copyright infringement since the user never is provided with a complete copy of the file.

When audio or video is streamed, a small buffer space is created on the user's computer, and data starts downloading into it. As soon as the buffer is full (usually 10-30 seconds), the file starts to play. As the file plays, it uses up information in the buffer, but while it is playing, more data is being downloaded. As long as the data can be downloaded as fast as it is used up in playback, the file will play smoothly. -Video/MP3/Audio
