Functions ¶

This section is empty.

Types ¶

type Document ¶

type Document struct {
	// contains filtered or unexported fields
}

Document represents a WebM file

func InitDocument ¶

func InitDocument(r io.Reader) *Document

InitDocument creates a MKV/WebM document containing the file data It does not do any parsing

func (*Document) GetElementContent ¶

func (doc *Document) GetElementContent(el *Element) ([]byte, error)

GetElementContent returns the element's data (if any) Data is present if the element's type is not Master

func (*Document) GetElementID ¶

func (doc *Document) GetElementID(el *Element) (uint32, error)

GetElementID tries to parse the next element's id, starting from the document's current cursor position.

func (*Document) GetElementSize ¶

type ElementRegister ¶

type ElementRegister struct {
	ID   uint32
	Type uint8
	Name string
}

ElementRegister contains the ID, type and name of the standard WebM/Matroska elements
