Types ¶
type H265Reader ¶
type H265Reader struct {
// contains filtered or unexported fields
}
H265Reader reads data from stream and constructs h265 nal units.
func NewReader ¶
func NewReader(in io.Reader) (*H265Reader, error)
NewReader creates new H265Reader.
func NewReaderWithOptions ¶ added in v4.2.0
func NewReaderWithOptions(in io.Reader, options ...Option) (*H265Reader, error)
NewReaderWithOptions creates new H265Reader with options. The default behavior is to skip SEI NAL units.
func (*H265Reader) NextNAL ¶
func (reader *H265Reader) NextNAL() (*NAL, error)
NextNAL reads from stream and returns then next NAL, and an error if there is incomplete frame data. Returns all nil values when no more NALs are available.
type NAL ¶
type NAL struct {
PictureOrderCount uint32

type NalUnitType ¶
type NalUnitType uint8
NalUnitType is the type of a NAL unit in H.265/HEVC.

Enums for H.265/HEVC NAL unit types.
func (*NalUnitType) String ¶
func (n *NalUnitType) String() string
type Option ¶ added in v4.2.0
type Option func(*H265Reader) error
Option configures the behavior of H265Reader.
func WithIncludeSEI ¶ added in v4.2.0
WithIncludeSEI controls whether SEI (Supplemental Enhancement Information) NAL units are returned. Default is false (SEI is skipped).
