GstCodecParsers.AV1TileGroupOBU¶

Fields¶

Name	Type	Access	Description
entry	[`GstCodecParsers.AV1TileGroupOBUEntry`]	r/w
num_tiles	`int`	r/w	specifies the total number of tiles in the frame.
tg_end	`int`	r/w	specifies the zero-based index of the last tile in the current tile group. It is a requirement of bitstream conformance that the value of tg_end is greater than or equal to tg_start. It is a requirement of bitstream conformance that the value of tg_end for the last tile group in each frame is equal to num_tiles-1.
tg_start	`int`	r/w	specifies the zero-based index of the first tile in the current tile group. It is a requirement of bitstream conformance that the value of tg_start is equal to the value of TileNum at the point that tile_group_obu is invoked.
tile_start_and_end_present_flag	`bool`	r/w	specifies whether tg_start and tg_end are present in the bitstream. If tg_start and tg_end are not present in the bitstream, this tile group covers the entire frame. If obu_type is equal to `GstCodecParsers.AV1OBUType.FRAME`, it is a requirement of bitstream conformance that the value of tile_start_and_end_present_flag is equal to 0.
