GstCodecParsers.H264NalUnit¶

Fields¶

Name	Type	Access	Description
data	`int`	r/w	The data array from which the NAL unit has been parsed, into which the offset and sc_offset apply.
extension_type	`int`	r/w	the extension type for prefix NAL/MVC/SVC
header_bytes	`int`	r/w	The size of the NALU header in bytes. The NALU header is the 1-byte type code, and for extension / prefix NALs includes the extension header bytes. offset + header_bytes is therefore the first byte of the actual packet payload.
idr_pic_flag	`int`	r/w	calculated idr_pic_flag
offset	`int`	r/w	The offset of the first byte of the NAL unit header, just after the start code.
ref_idc	`int`	r/w	not equal to 0 specifies that the content of the NAL unit contains a sequence parameter set, a sequence parameter set extension, a subset sequence parameter set, a picture parameter set, a slice of a reference picture, a slice data partition of a reference picture, or a prefix NAL unit preceding a slice of a reference picture.
sc_offset	`int`	r/w	The offset of the first byte of the start code of the NAL unit.
size	`int`	r/w	The size of the NAL unit starting from offset, thus including the header bytes. e.g. type (nal_unit_type), but not the start code.
type	`int`	r/w	A `GstCodecParsers.H264NalUnitType`
valid	`bool`	r/w	If the NAL unit is valid, which means it has already been parsed

None
