Performance control in video encoding

摘要

An apparatus having a circuit is disclosed. The circuit may be configured to (i) generate a complexity value by encoding a current picture in a video signal, where the current picture is encoded using a current one of a plurality of configurations, (ii) calculate an estimate in response to the complexity value and (iii) reconfigure the encoding into a new one of the configurations in response to the estimate relative to one or more thresholds. The configurations may include a normal configuration and one or more simplified configurations. The estimate generally describes a computational stress that the encoding of the current picture placed on the circuit. The new configuration may be different from the current configuration.

1. An apparatus comprising:
a circuit configured to (i) generate a complexity value by encoding a current picture in a video signal, wherein said current picture is encoded using a current one of a plurality of configurations, (ii) calculate an estimate in response to said complexity value and (iii) reconfigure said encoding into a new one of said configurations in response to said estimate relative to one or more thresholds, wherein (a) said configurations comprise a normal configuration and one or more simplified configurations, (b) said estimate describes a computational stress that said encoding of said current picture placed on said circuit and (c) said new configuration is different from said current configuration, wherein said circuit is further configured to delay said reconfiguration where said new configuration increases a number of tools used in said encoding compared with said current configuration; wherein said reconfiguration bypasses said delay where said new configuration decreases said number of tools used in said encoding compared with said current configuration.
