How HDFVR records video clips:

1. User goes to your website.

   Having a video recorder on your website will make this step easier!

2. User reaches the page with the video recorder embedded in it.

   When the user loads in the browser the HTML page in which the video recorder is embedded, the video recorder .swf file travels from the webserver to the users computer where it is loaded in the browser by Flash Player.

3. The video recorder connects to the media server.

   The video recorder will first ask the user what webcam and sound card to use for capturing video and audio, after that,when the user presses the RECORD button a connection is made to the media server for sending data to it. The connection is made only when the user presses the RECORD button so that the media server is not overloaded with connection attempts.

4. Audio and video data is captured, encoded, and sent to the media server.

   The video recorder will now capture audio and video data , encode it, (audio with the NellyMoser or Speex codecs and video with Spark) and put it in a small client side buffer from where it is sent to the media server.

5. The media server saves the video and audio data in .flv files.

   When the encoded audio and video data reaches the media server it is stored in .flv files in a folder inside the media server installation folder.

6. The info about the new video is saved to your database

   When the users presses the [SAVE] button an API call is made to both the JS and PHP API's. You can leverage these API's to save the recording info (length, size, name) in your database.

 

How playback works: The recording process results in .flv files stored on the media server, here is how you can play them back on your website: play them directly from the media server trough streaming move them to a web server and play them trough progressive download move them to a web server and make them available for download
