How to add progressive video to your site
Wednesday, April 22nd, 2009Adding video to your site is cool, ok!
So you want to get with the program and add some video to your website, and who would blame you, video is cool and everyone knows it. But how “Jason”? I hear you mumble, well I hope to show you below
Progressive download via HTTP (supported in Flash Player 7 and later). This method uses ActionScript to include an externally hosted Flash Video file client-side for playback. Progressive download has several advantages, including buffering, use of generic HTTP servers, and the ability to reuse a single SWF player for multiple Flash Video sources. Flash Player 8 includes support for random access within video files using the partial download functionality of HTTP, sometimes this is referred to as streaming. However, unlike streaming using RTMP, HTTP “streaming” does not support real-time broadcasting. Streaming via HTTP requires a custom player and the injection of specific Flash Video metadata containing the exact starting position in bytes and timecode of each keyframe. Using this specific information, a custom Flash Video player can request any part of the Flash Video file starting at a specified keyframe. For example, Google Video and Youtube support progressive downloading and can seek to any part of the video before buffering is complete. The server-side part of this “HTTP pseudo-streaming” method is fairly simple to implement, for example using our myFLV Ispai filter you can choose almost any scripting language as long as it allows you to embed objects.
