Constants

UNSIGNED_INT_MAX_VALUE

const val UNSIGNED_INT_MAX_VALUE = 4294967295: Long

The maximum value of a 32-bit unsigned int.

Public functions

createMotionPhotoFromJpegImageAndBmffVideo

java-static fun createMotionPhotoFromJpegImageAndBmffVideo(
    imageInputStream: FileInputStream!,
    imagePresentationTimestampUs: Long,
    videoInputStream: FileInputStream!,
    videoContainerMimeType: String!,
    outputChannel: WritableByteChannel!
): Unit

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

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

java-static fun getMuxerBufferInfoFromMediaCodecBufferInfo(
    mediaCodecBufferInfo: MediaCodec.BufferInfo!
): BufferInfo!

Returns BufferInfo corresponding to the MediaCodec.BufferInfo.

isMetadataSupported

java-static fun isMetadataSupported(metadata: Metadata.Entry!): Boolean

Returns whether a given metadata is supported.
