Field Documentation

◆ bit_depth_minus_8

uint32_t _RocDecoderCreateInfo::bit_depth_minus_8

IN: The value "BitDepth minus 8"

◆ chroma_format

rocDecVideoChromaFormat _RocDecoderCreateInfo::chroma_format

IN: rocDecVideoChromaFormat_XXX

◆ codec_type

rocDecVideoCodec _RocDecoderCreateInfo::codec_type

IN: rocDecVideoCodec_XXX

◆ device_id

uint8_t _RocDecoderCreateInfo::device_id

IN: the device id for which a decoder should be created 0 for the first device, 1 for the second device on the system, etc.

◆ 

struct { ... } _RocDecoderCreateInfo::display_rect

IN: area of the frame that should be displayed

◆ height

uint32_t _RocDecoderCreateInfo::height

IN: Coded sequence height in pixels

◆ intra_decode_only

uint32_t _RocDecoderCreateInfo::intra_decode_only

IN: Set 1 only if video has all intra frames (default value is 0). This will optimize video memory for Intra frames only decoding. The support is limited to specific codecs - AVC/H264, HEVC, VP9, the flag will be ignored for codecs which are not supported. However decoding might fail if the flag is enabled in case of supported codecs for regular bit streams having P and/or B frames.

◆ max_height

uint32_t _RocDecoderCreateInfo::max_height

IN: Coded sequence max height in pixels used with reconfigure Decoder

◆ max_width

uint32_t _RocDecoderCreateInfo::max_width

IN: Coded sequence max width in pixels used with reconfigure Decoder

◆ num_decode_surfaces

uint32_t _RocDecoderCreateInfo::num_decode_surfaces

IN: Maximum number of internal decode surfaces

◆ num_output_surfaces

uint32_t _RocDecoderCreateInfo::num_output_surfaces

IN: Maximum number of output surfaces simultaneously mapped

◆ output_format

rocDecVideoSurfaceFormat _RocDecoderCreateInfo::output_format

IN: rocDecVideoSurfaceFormat_XXX

◆ reserved_2

uint32_t _RocDecoderCreateInfo::reserved_2[4]

Reserved for future use - set to zero

◆ target_height

uint32_t _RocDecoderCreateInfo::target_height

IN: Post-processed output height (Should be aligned to 2)

◆ 

struct { ... } _RocDecoderCreateInfo::target_rect

IN: (for future use) target rectangle in the output frame (for aspect ratio conversion) if a null rectangle is specified, {0,0,target_width,target_height} will be used

◆ target_width

uint32_t _RocDecoderCreateInfo::target_width

IN: Post-processed output width (Should be aligned to 2)

◆ width

uint32_t _RocDecoderCreateInfo::width

IN: Coded sequence width in pixels
