Used in Parser callback API.
Video format including raw sequence header information Used in rocDecCreateVideoParser API
Field Documentation
◆ bit_depth_chroma_minus8
| uint8_t RocdecVideoFormat::bit_depth_chroma_minus8 |
OUT: high bit depth chroma. E.g, 2 for 10-bitdepth, 4 for 12-bitdepth
◆ bit_depth_luma_minus8
| uint8_t RocdecVideoFormat::bit_depth_luma_minus8 |
OUT: high bit depth luma. E.g, 2 for 10-bitdepth, 4 for 12-bitdepth
◆ bitrate
| uint32_t RocdecVideoFormat::bitrate |
OUT: video bitrate (bps, 0=unknown)
◆ bottom
| int RocdecVideoFormat::bottom |
OUT: bottom position of display rect
◆ chroma_format
| rocDecVideoChromaFormat RocdecVideoFormat::chroma_format |
OUT: Chroma format
◆ codec
| rocDecVideoCodec RocdecVideoFormat::codec |
OUT: Compression format
◆ coded_height
| uint32_t RocdecVideoFormat::coded_height |
OUT: coded frame height in pixels
◆ coded_width
| uint32_t RocdecVideoFormat::coded_width |
OUT: coded frame width in pixels
◆ color_primaries
| uint8_t RocdecVideoFormat::color_primaries |
OUT: chromaticity coordinates of source primaries
◆
| struct { ... } RocdecVideoFormat::display_area |
area of the frame that should be displayed typical example: coded_width = 1920, coded_height = 1088 display_area = { 0,0,1920,1080 }
◆
| struct { ... } RocdecVideoFormat::display_aspect_ratio |
OUT: Display Aspect Ratio = x:y (4:3, 16:9, etc)
◆
| struct { ... } RocdecVideoFormat::frame_rate |
OUT: frame rate = numerator / denominator (for example: 30000/1001)
◆ left
| int RocdecVideoFormat::left |
OUT: left position of display rect
◆ matrix_coefficients
| uint8_t RocdecVideoFormat::matrix_coefficients |
OUT: used in deriving luma and chroma signals from RGB primaries
◆ min_num_decode_surfaces
| uint8_t RocdecVideoFormat::min_num_decode_surfaces |
OUT: Minimum number of decode surfaces to be allocated for correct decoding. The client can send this value in num_decode_surfaces. This guarantees correct functionality and optimal video memory usage but not necessarily the best performance, which depends on the design of the overall application. The optimal number of decode surfaces (in terms of performance and memory utilization) should be decided by experimentation for each application, but it cannot go below min_num_decode_surfaces. If this value is used for num_decode_surfaces then it must be returned to parser during sequence callback.
◆ numerator
| uint32_t RocdecVideoFormat::numerator |
< OUT: frame rate numerator (0 = unspecified or variable frame rate) OUT: frame rate denominator (0 = unspecified or variable frame rate)
◆ progressive_sequence
| uint8_t RocdecVideoFormat::progressive_sequence |
OUT: 0=interlaced, 1=progressive
◆ reserved_zero_bits
| uint8_t RocdecVideoFormat::reserved_zero_bits |
Reserved bits
◆ right
| int RocdecVideoFormat::right |
OUT: right position of display rect
◆ seqhdr_data_length
| uint32_t RocdecVideoFormat::seqhdr_data_length |
OUT: Additional bytes following (RocdecVideoFormatEx)
◆ top
| int RocdecVideoFormat::top |
OUT: top position of display rect
◆ transfer_characteristics
| uint8_t RocdecVideoFormat::transfer_characteristics |
OUT: opto-electronic transfer characteristic of the source picture
◆ video_format
| uint8_t RocdecVideoFormat::video_format |
OUT: 0-Component, 1-PAL, 2-NTSC, 3-SECAM, 4-MAC, 5-Unspecified
◆ video_full_range_flag
| uint8_t RocdecVideoFormat::video_full_range_flag |
OUT: indicates the black level and luma and chroma range
