This information is not useful to an application at runtime, but may be of use to aom for support. - - \section usage_deadline Deadline - Both the encoding and decoding functions have a <code>deadline</code> - parameter. This parameter indicates the amount of time, in microseconds - (us), that the application wants the codec to spend processing before - returning. This is a soft deadline -- that is, the semantics of the - requested operation take precedence over meeting the deadline. If, for - example, an application sets a <code>deadline</code> of 1000us, and the - frame takes 2000us to decode, the call to aom_codec_decode() will return - after 2000us. In this case the deadline is not met, but the semantics of the - function are preserved. If, for the same frame, an application instead sets - a <code>deadline</code> of 5000us, the decoder will see that it has 3000us - remaining in its time slice when decoding completes. It could then choose to - run a set of \ref usage_postproc filters, and perhaps would return after - 4000us (instead of the allocated 5000us). In this case the deadline is met, - and the semantics of the call are preserved, as before. - - The special value <code>0</code> is reserved to represent an infinite - deadline. In this case, the codec will perform as much processing as - possible to yield the highest quality frame. - - By convention, the value <code>1</code> is used to mean "return as fast as - possible." - */ |
