# GstH265Parser

It offers you bitstream parsing in HEVC mode and non-HEVC mode. To identify Nals in a bitstream and parse its headers, you should call:

- gst_h265_parser_identify_nalu to identify the following nalu in non-HEVC bitstreams

- gst_h265_parser_identify_nalu_hevc to identify the nalu in HEVC bitstreams

Then, depending on the GstH265NalUnitType of the newly parsed GstH265NalUnit, you should call the differents functions to parse the structure:

- From GST_H265_NAL_SLICE_TRAIL_N to GST_H265_NAL_SLICE_CRA_NUT: gst_h265_parser_parse_slice_hdr

- `GST_H265_NAL_*_SEI`: gst_h265_parser_parse_sei

- GST_H265_NAL_VPS: gst_h265_parser_parse_vps

- GST_H265_NAL_SPS: gst_h265_parser_parse_sps

- GST_H265_NAL_PPS: gst_h265_parser_parse_pps()

- Any other: gst_h265_parser_parse_nal

Note: You should always call gst_h265_parser_parse_nal if you don't actually need GstH265NalUnitType to be parsed for your personal use, in order to guarantee that the GstH265Parser is always up to date.

For more details about the structures, look at the ITU-T H.265 specifications, you can download them from:
