Nalu Class

Creates an empty NAL Unit.

Creates a NAL Unit from a byte array.

Gets the bottom_field_flag.

Gets the backing DataBuffer.

Gets the pic_order_cnt_lsb

Gets the forbidden Zero Bit. The H.264 specification declares a value of 1 as a syntax violation.

Gets the forbidden zero bit mask.

Gets the field_pic_flag.

Gets the first_mb_in_slice specifies the address of the first macroblock in the slice. When arbitrary slice order is not allowed as specified in Annex A, the value of first_mb_in_slice is constrained as follows: – If separate_colour_plane_flag is equal to 0, the value of first_mb_in_slice shall not be less than the value of first_mb_in_slice for any other slice of the current picture that precedes the current slice in decoding order. – Otherwise (separate_colour_plane_flag is equal to 1), the value of first_mb_in_slice shall not be less than the value of first_mb_in_slice for any other slice of the current picture that precedes the current slice in decoding order and has the same value of colour_plane_id.

Gets the frame_num: The Frame Number is used as an identifier for pictures and shall be represented by log2_max_frame_num_minus4 + 4 bits in the bitstream.

Gets the NAL header.

Gets the idr_pic_flag.

Gets the idr_pic_id: The values of idr_pic_id in all the slices of an IDR picture shall remain unchanged. When two consecutive access units in decoding order are both IDR access units, the value of idr_pic_id in the slices of the first such IDR access unit shall differ from the idr_pic_id in the second such IDR access unit. The value of idr_pic_id shall be in the range of 0 to 65535, inclusive.

Gets the NRI: 2bits otherwise known as nal_ref_idc.

Gets the nal_ref_idc mask.

Gets or sets the NAL payload.

Gets the pic_order_cnt_lsb.

Gets the pic_order_cnt_type.

Gets the Picture Parameter Set specifies the picture parameter set in use. The value of pic_parameter_set_id shall be in the range of 0 to 255, inclusive.

Gets the size of the NAL Unit (including NAL header) in two octets stored in the returned byte array. Useful for creating certain types of H264 such as STAP.

Gets the type of Slice contained in this NAL.

Gets the Sequence Parameter Set this NAL references.

Gets the 4-byte NALU start code.

Gets the NAL Unit Type.

Gets the NAL Unit Type mask.

Scans for the index of the first NAL Unit after start.

Scans for the index of the first NAL Unit after start.

Gets the NAL Unit as a byte array that can be passed to an encoder (includes Start Code).

Returns the first NAL unit after nalStart.

Returns the first NAL unit after nalStart.
