Different rate controller configurations for different cameras of a mobile device
Some embodiments provide a method for encoding video pictures captured by a mobile device having at least first and second cameras. The method identifies a first rate controller parameter that is based on at least a first value that quantifies one characteristic of the first camera. The method uses the first rate controller parameter to configure a set of rate controllers to adjust a bit rate for encoding video pictures captured by the first camera. The method identifies a second rate controller parameter that is based on at least a second value that quantifies the same characteristic of the second camera. The first and second values are different, and the difference causes the first and second rate controller parameters to be different. The method uses the second rate controller parameter to configure the set of rate controllers to adjust a bit rate for encoding video pictures captured by the second camera.
