Types ¶
type LQTPerformance ¶
type LazyQuicktime ¶
type LazyQuicktime struct {
Source lazyfs.FileSource
Tree quicktime.AtomArray
Trak quicktime.TRAKAtom
Stbl *quicktime.STBLAtom
Mvhd quicktime.MVHDAtom
FileSize int64
}
LazyQuicktime stores the metadata from a Quicktime Movie extracted via a lazyFS. Stores a copy of the lazyFS to allow lazy-loading
func LoadMovMetadata ¶
func LoadMovMetadata(file lazyfs.FileSource) (*LazyQuicktime, error)
LoadMovMetadata creates a LazyQuicktime by querying a lazyfs.FileSource.
func (*LazyQuicktime) Duration ¶
func (mov *LazyQuicktime) Duration() time.Duration
Duration reports the length of the LazyQuicktime in seconds.
func (*LazyQuicktime) ExtractFrame ¶
func (mov *LazyQuicktime) ExtractFrame(frame uint64) (image.Image, error)
ExtractFrame extracts an individual frame from a ProRes file as an Image
func (*LazyQuicktime) ExtractFramePerf ¶
func (mov *LazyQuicktime) ExtractFramePerf(frame uint64) (image.Image, LQTPerformance, error)
ExtractFrame extracts an individual frame from a ProRes file as an Image
func (*LazyQuicktime) ExtractNRGBA ¶
func (mov *LazyQuicktime) ExtractNRGBA(frame uint64) (*image.NRGBA, error)
ExtractNRGBA extracts an individual frame from a ProRes file as an image.NRGBA in its native height
func (*LazyQuicktime) ExtractNRGBAPerf ¶
func (mov *LazyQuicktime) ExtractNRGBAPerf(frame uint64) (*image.NRGBA, LQTPerformance, error)
ExtractNRGBAPerf extracts an individual frame from a ProRes file as an image.NRGBA and also returns performance information in an LQTPerformance structure
func (*LazyQuicktime) NumFrames ¶
func (mov *LazyQuicktime) NumFrames() uint64
NumFrames reports the number of frames in the LazyQuicktime
