Abstract:
1. A computer implemented method, comprising: allocating a source memory and a destination memory for a decoder process to perform decoding operations using the source memory; in response to an API (Application Programming Interface) request to decode compressed content data from an application process separate from the decoder process, initializing the decoder process to perform the decoding operations on the compressed content data; in response to a relinquishing request from the decoder process to restrict access rights of the decoder process for resources other than the source and destination memories, configuring an access control with the restricted access rights of the decoder process; and preventing the decoder process from accessing resources other than the source and destination memories during decoding the compressed content data via the configured access control, wherein the destination memory is used to store the decoded content data and wherein a playing device is to play media content based on the decoded content data.
