v4l2_ctrl_vp8_frame Struct Reference

Detailed Description

struct v4l2_ctrl_vp8_frame - VP8 frame parameters

@segment: segmentation parameters. See &v4l2_vp8_segment for more details @lf: loop filter parameters. See &v4l2_vp8_loop_filter for more details @quant: quantization parameters. See &v4l2_vp8_quantization for more details @entropy: update probabilities. See &v4l2_vp8_entropy for more details @coder_state: boolean coder state. See &v4l2_vp8_entropy_coder_state for more details @width: frame width. @height: frame height. @horizontal_scale: horizontal scaling factor. @vertical_scale: vertical scaling factor.

Version
: bitstream version. @prob_skip_false: frame header syntax element. @prob_intra: frame header syntax element. @prob_last: frame header syntax element. @prob_gf: frame header syntax element. @num_dct_parts: number of DCT coefficients partitions. @first_part_size: size of the first partition, i.e. the control partition. @first_part_header_bits: size in bits of the first partition header portion. @dct_part_sizes: DCT coefficients sizes. @last_frame_ts: "last" reference buffer timestamp. The timestamp refers to the timestamp field in struct v4l2_buffer. Use v4l2_timeval_to_ns() to convert the struct timeval to a __u64. @golden_frame_ts: "golden" reference buffer timestamp. @alt_frame_ts: "alt" reference buffer timestamp. @flags: see V4L2_VP8_FRAME_FLAG_{}.
