Video/audio switching in a computing device

摘要

Video/audio switching techniques for control of an application running on a computing device. In accordance with an example technique, video and associated audio signals provided from a source for playback at the computing device are processed. It is detected that the application has been placed into the background or a suspend state and the processing of the video signals is terminated without affecting processing of the audio signals.

主权项

1. A method for control of a combined video/audio application executed at a computing device, comprising:
receiving, at a demultiplexer of a playback module of the computing device, a packaged combined video/audio file from a source, wherein the packaged combined video/audio file comprises audio signals that are associated with video signals; separating, with the demultiplexer, the audio signals from the video signals; processing the video signals separated from the audio signals for display at a display screen of the computing device; processing the audio signals separated from the video signals for playback at an audio output of the computing device; detecting, with a video/audio switching plug-in associated with the video/audio application, that the computing device has been placed in a suspend state where the display screen of the computing device is de-activated; transmitting a disable signal from the video/audio switching plug-in to the demultiplexer to cause the demultiplexer to cease output of video signals; and continuing to process the audio signals at the demultiplexer even though the video signals are no longer processed by the demultiplexer.
