Constants

UNSIGNED_INT_MAX_VALUE

public static final long UNSIGNED_INT_MAX_VALUE = 4294967295

The maximum value of a 32-bit unsigned int.

Public methods

createMotionPhotoFromJpegImageAndBmffVideo

public static void createMotionPhotoFromJpegImageAndBmffVideo(
    FileInputStream imageInputStream,
    long imagePresentationTimestampUs,
    FileInputStream videoInputStream,
    String videoContainerMimeType,
    WritableByteChannel outputChannel
)

Creates a Motion Photo from a JPEG image and a BMFF video as per the Motion Photo spec.

Parameters
`FileInputStream imageInputStream`	A `FileInputStream` containing the image data. The caller is responsible for closing the stream once this method returns.
`long imagePresentationTimestampUs`	The presentation timestamp of the image in the video (in microseconds).
`FileInputStream videoInputStream`	A `FileInputStream` containing the video data. The caller is responsible for closing the stream once this method returns.
`String videoContainerMimeType`	The container mime type of the video. Must be `VIDEO_MP4` or `VIDEO_QUICK_TIME`.
`WritableByteChannel outputChannel`	A `WritableByteChannel` to write output to. The caller is responsible for closing the channel once this method returns.

Throws
`java.io.IOException`	If an error occurs when creating the Motion Photo.

getMuxerBufferInfoFromMediaCodecBufferInfo

public static BufferInfo getMuxerBufferInfoFromMediaCodecBufferInfo(
    MediaCodec.BufferInfo mediaCodecBufferInfo
)

Returns BufferInfo corresponding to the MediaCodec.BufferInfo.

isMetadataSupported

public static boolean isMetadataSupported(Metadata.Entry metadata)

Returns whether a given metadata is supported.
