Method Detail

init

public void init(int configFrameRate,
                 int configCodeRate,
                 int minCodeRate,
                 float reduceFrameWeight)

初始化参数,设置新的编码器后要重新初始化

Parameters:

configFrameRate - 设置的帧率

configCodeRate - 设置的码率

minCodeRate - 当达到这个码率时,才会降帧

reduceFrameWeight - 降帧的权重 0.0~1.0

onInterceptDoFrame

public boolean onInterceptDoFrame(long timeStampNanos)

Description copied from interface: IFrameRateModify

是否拦截当前摄像头的帧

Specified by:

onInterceptDoFrame in interface IFrameRateModify

Returns:

true 拦截不处理,丢帧吧
