Members

Member	Description
timing_mode	Video timing, which must correspond to the VO input timing. Otherwise, undefined behavior may occur, affecting the display.
color_space	Color space, which must correspond to the VO input color space. Set this parameter to HI_HDMI_COLOR_SPACE_YCBCR444 when sending images.
active_info_present	Whether the information is valid. In the current version, this parameter can only be set to HI_FALSE.
bar_info	Panel information. In the current version, this parameter can only be set to HI_HDMI_BAR_INFO_NOT_VALID.
scan_info	Scanning information. In the current version, this parameter can only be set to HI_HDMI_SCAN_INFO_NO_DATA.
colorimetry	Color gamut. In the current version, this parameter can only be set to HI_HDMI_COMMON_COLORIMETRY_ITU601.
ex_colorimetry	Color gamut extension. In the current version, this parameter can only be set to HI_HDMI_COMMON_COLORIMETRY_XVYCC_601.
aspect_ratio;	Image aspect ratio. In the current version, this parameter can only be set to HI_HDMI_PIC_ASPECT_RATIO_4TO3 or HI_HDMI_PIC_ASPECT_RATIO_16TO9.
active_aspect_ratio	Actual valid image aspect ratio. In the current version, this parameter can only be set to HI_HDMI_ACTIVE_ASPECT_RATIO_SAME_PIC.
pic_scaling	Image scanning. In the current version, this parameter can only be set to HI_HDMI_PIC_NON_UNIFORM_SCALING.
rgb_quant	RGB quantization. In the current version, this parameter can only be set to HI_HDMI_RGB_QUANT_FULL_RANGE.
is_it_content	Valid content determination. In the current version, this parameter can only be set to HI_FALSE.
pixel_repetition	Pixel repetition. In the current version, this parameter can only be set to HI_HDMI_PIXEL_REPET_NO.
content_type	Content information type. In the current version, this parameter can only be set to HI_HDMI_CONTNET_PHOTO.
ycc_quant	YUV quantization. In the current version, this parameter can only be set to HI_HDMI_YCC_QUANT_FULL_RANGE.
line_n_end_of_top_bar	Top end lines. In the current version, this parameter can only be set to 0.
line_n_start_of_bot_bar	Bottom start lines. In the current version, this parameter can only be set to 0.
pixel_n_end_of_left_bar	Left end pixels. In the current version, this parameter can only be set to 0.
pixel_n_start_of_right_bar	Right start pixels. In the current version, this parameter can only be set to 0.
