Types ¶
type Atom ¶
type Atom struct {
Path string // Path is the dot separated code of the parents and of this atom (ex: moov.trak.hvdt)
Code string // Code is the 4 chars code used in MP4 specifications
IsParent bool // IsParent is TRUE when the Atom type is reconised to have children. The payload should not be read in this case.
Size uint64 // Size is the total size of the Atom, including children (in bytes)
// contains filtered or unexported fields
}
Atom is a chunk in a MP4 files, structured as a tree
type AtomDecoder ¶
type AtomDecoder struct {
// contains filtered or unexported fields
}
AtomDecoder reads an MP4 file to extract Atom
func NewAtomDecoder ¶
func NewAtomDecoder(reader io.Reader) *AtomDecoder
NewAtomDecoder will start parsing an MP4 files
func (*AtomDecoder) Next ¶
func (d *AtomDecoder) Next() (*Atom, *PayloadIterator, error)
Next reads and returns the next Atom (or children Atom). It will consume any payload not yet read. It will return (nil, nil, io.EOF) when the file has been read fully.
type Parser ¶
type Parser struct {
Debug bool
}
func (*Parser) ReadDetails ¶
func (p *Parser) ReadDetails(reader io.Reader, options backupmodel.DetailsReaderOptions) (*backupmodel.MediaDetails, error)
func (*Parser) Supports ¶
func (p *Parser) Supports(media backupmodel.FoundMedia, mediaType backupmodel.MediaType) bool
type PayloadIterator ¶
type PayloadIterator struct {
// contains filtered or unexported fields
}
PayloadIterator is used to get content of the Atom as a []byte
func (*PayloadIterator) HasNext ¶
func (p *PayloadIterator) HasNext() bool
HasNext returns TRUE if some payload remains within the Atom.
