HTTP Progressive Download uses the HTTP protocol to stream archived media content. As a result, it cannot take advantage of the security features that are available with the RTMP protocol, such as encryption and SWF verification. Additionally, the entire video is downloaded to a user's computer. As a result of all of these factors, HTTP Progressive Download is more susceptible to piracy than some of our other streaming solutions.
As previously mentioned, the HTTP Progressive Download uses the HTTP protocol to stream video on-demand. Specifically, HTTP Progressive Download should only be used with the HTTP Large platform. This allows progressively downloaded content to take advantage of all of the features provided by the HTTP Large platform. For example, you can use an existing customer origin to indicate the location of your video content.
Any type of asset supported by your video player can be streamed through HTTP Progressive Download. However, seeking within a video is only supported for H.264 encoded video.
