Preparing Streaming Media

Web pages and media to be served out via HTTP can simply be placed in this directory to appear at the above base URL. In addition to the stardard HTTP server we also have a QTSS real-time streaming protocol (RTSP) server that is optimized for larger/longer media files. From an end-users perspective, the primary difference between HTTP and RTSP served media is the ability to jump around with instant playback. HTTP-served media must be downloaded for playback, and it downloads sequentially the user can only play what has been downloaded. RTSP streams the media to the user in real-time and has the ability to start anywhere and jump around without downloading the entire file.

If you would like to use the RTSP server, simply place your streaming files within the “qtss” folder inside of your FTP (website) home directory and access them using the Quicktime Player “Open URL” option (or other RTSP client) with the base URL format of:

rtsp://qtss.music.vt.edu/path/to/your-website/your-file.mov

Please note that this URL might not work directly with most web browsers. To work around this, reference movies can be created with internal links to RTSP content for use within standard web pages. The basic process for creating a reference movie is:

  1. create the media, exporting from Quicktime as “hinted for streaming”
  2. upload the media to the “qtss” folder of your website (via FTP)
  3. open this media using the RTSP method described above
  4. stop playback and move the playback head to the beginning
  5. save the file as a standard quicktime movie, ending in “.mov”

This standard quicktime (reference) movie will work as a regular movie file; uploaded to the webserver, used within HTML, emailed etc. as long as the receipent has an internet connection

See the “Delivery Tutorials” at the Apple Quicktime website for more information.
