Expand description

The data description for metadata

Implementations

impl MetaData

pub fn new(length: u32, timecode: i64, data: String) -> Self

Create new metadata struct

pub fn length(&self) -> u32

The length of the string in UTF8 characters. This includes the NULL terminating character. If this is 0, then the length is assumed to be the length of a NULL terminated string.

pub fn timecode(&self) -> i64

The timecode of this frame in 100ns intervals

pub fn data(&self) -> String

The metadata as a UTF8 XML string. This is a NULL terminated string. according to the docs, metadata should be valid UTF-8 XML not sure how much it’s actually followed in practice
