Field Value

Attributes

Remarks

A key describing the frequency of key frames expressed in seconds between key frames.

This key is used by video encoders. A negative value means no key frames are requested after the first frame. A zero value means a stream containing all key frames is requested. <p class=note> Most video encoders will convert this value of the number of non-key-frames between key-frames, using the #KEY_FRAME_RATE frame rate information; therefore, if the actual frame rate differs (e.g. input frames are dropped or the frame rate changes), the <strong>time interval</strong> between key frames will not be the configured value.

The associated value is an integer (or float since android.os.Build.VERSION_CODES#N_MR1).
