A method includes initiating media player instances for producing output by execution on an electronic device. Each of the media player instances is implemented using a modular framework on the electronic device configured to have each of multiple types of media player runtimes implemented therein and to host modules that configure any of the types of media player runtimes for respective device types. The method includes determining, using a sound module of the modular framework, which of the media player instances should be used for audio output by the electronic device. The method includes generating the audio output using the electronic device, the audio output produced by at least one of the media player instances as determined.

Managing media player sound output

An audio and video decoder for decoding audio, video and sub-picture streams in a disc player. The audio and video decoder has associated therewith a memory for storing commands and status information for each command. The audio and video decoder is responsive to commands received from a host to control audio and video decoding processes. The audio and video decoder includes a host interface and a command processor. The command processor includes a transfer mechanism for transferring commands received at a command buffer in the memory to a command FIFO in the memory and a status monitor for tracking an execution status of each command stored in the command FIFO and for updating a status word which is stored along with each command in the command FIFO. The command processor returns a pointer to the host for a unique address in memory for the status word for each command stored in the command FIFO.
