Method Detail

• getBitRate

   final Integer getBitRate()

  A key describing the average bitrate in bits/sec. The associated value is an integer

• getFrameRate

   final Integer getFrameRate()

  A key describing the frame rate of a video format in frames/sec. The associated value is normally an integer when the value is used by the platform, but video codecs also accept float configuration values. Specifically, MediaExtractor#getTrackFormat provides an integer value corresponding to the frame rate information of the track if specified and non-zero. Otherwise, this key is not present. MediaCodec#configure accepts both float and integer values. This represents the desired operating frame rate if the KEY_OPERATING_RATE is not present and KEY_PRIORITY is 0 (realtime). For video encoders this value corresponds to the intended frame rate, although encoders are expected to support variable frame rate based on MediaCodec.BufferInfo#presentationTimeUs. This key is not used in the MediaCodec MediaCodec#getInputFormat/MediaCodec#getOutputFormat formats, nor by MediaMuxer#addTrack.

• getIFrameInterval

   final Integer getIFrameInterval()

  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.

  Most video encoders will convert this value of the number of non-key-frames between key-frames, using the frame rate information; therefore, if the actual frame rate differs (e.g. input frames are dropped or the frame rate changes), the time interval between key frames will not be the configured value.

• getMimeType

   final String getMimeType()

  The mime type of the content. This value must never be null.
