MAX_FRAME_SIZE_BYTES

public static final int MAX_FRAME_SIZE_BYTES

Deprecated.

Theoretical maximum frame size for an MPEG audio stream, which occurs when playing a Layer 2 MPEG 2.5 audio stream at 16 kb/s (with padding). The size is 1152 sample/frame * 160000 bit/s / (8000 sample/s * 8 bit/byte) + 1 padding byte/frame = 2881 byte/frame. The next power of two size is 4 KiB. See Also:Constant Field Values

-

MAX_RATE_BYTES_PER_SECOND

public static final int MAX_RATE_BYTES_PER_SECOND

Deprecated.

Maximum rate for an MPEG audio stream corresponding to MPEG-1 layer III (320 kbit/s), in bytes per second. See Also:Constant Field Values

Method Detail

-

getFrameSize

public static int getFrameSize​(int headerData)

Deprecated.

Returns the size of the frame associated with header, or C.LENGTH_UNSET if it is invalid.

-

parseMpegAudioFrameSampleCount

public static int parseMpegAudioFrameSampleCount​(int headerData)

Deprecated.

Returns the number of samples per frame associated with headerData, or C.LENGTH_UNSET if it is invalid.
