Script-based video rendering

Systems and methods are provided for cross-platform rendering of video content on a user-computing platform that is one type of a plurality of different user-computing platform types. A script is transmitted to the user-computing platform and is interpreted by an application program compiled to operate on any one of the plurality of user-computing platform types. Transmitting the script causes the script to be interpreted by the application program operating on the user-computing platform to cause the interpreted script to directly decode encoded video data transmitted or otherwise accessible to the user-computing platform into decoded video data and to further cause the rendering of the decoded video data.
