Member	Description
video_signal_type_present_flag	Int, flag that indicates whether the video signal information in the VUI field takes effect. The value can be 0 or 1 (default). Other parameters in the table are valid only when this flag is set to 1.
video_format	Int. For details, see the H.264/H.265 protocol. The default value is 5. Value range: [0, 7] for H.264; [0, 5] for H.265.
video_full_range_flag	Int. For details, see the H.264/H.265 protocol. The value can be 0 (default) or 1. If this parameter is set to 0, the pixel value range is limited. The luminance value range is 16–235, and the chrominance value range is 16–240.
colour_description_present_flag	Int. For details, see the H.264/H.265 protocol. The default value is 1. You do not need to set this parameter because the system sets it based on the actual image information.
colour_primaries	Int. For details, see the H.264/H.265 protocol. The default value is 1. You do not need to set this parameter because the system sets it based on the actual image information.
transfer_characteristics	Int. For details, see the H.264/H.265 protocol. The default value is 1. You do not need to set this parameter because the system sets it based on the actual image information.
matrix_coefficients	Int. For details, see the H.264/H.265 protocol. The default value is 1. You do not need to set this parameter because the system sets it based on the actual image information.
