A Native Client-based remote display client can efficiently perform multimedia redirection by routing un-rendered multimedia content to browser code executing outside the sandbox in which the remote display client is executed. In this way, a remote display client implemented as a Native Client module will not be limited to using the APIs available within the sandbox to render the multimedia content. The Native Client module can communicate with the browser code to provide parameters necessary for the browser code to submit a web-based request to the Native Client module via localhost to thereby obtain the multimedia content via one or more web-based communications.
