Struct AVVideoEncParams

#[repr(C)]
pub struct AVVideoEncParams {
    pub nb_blocks: u32,
    pub blocks_offset: usize,
    pub block_size: usize,
    pub type_: i32,
    pub qp: i32,
    pub delta_qp: [[i32; 2]; 4],
}

Video encoding parameters for a given frame. This struct is allocated along with an optional array of per-block AVVideoBlockParams descriptors. Must be allocated with av_video_enc_params_alloc().

Fields

nb_blocks: u32

Number of blocks in the array.

May be 0, in which case no per-block information is present. In this case the values of blocks_offset / block_size are unspecified and should not be accessed.

blocks_offset: usize

Offset in bytes from the beginning of this structure at which the array of blocks starts.

block_size: usize

type_: i32

Type of the parameters (the codec they are used with).

qp: i32

Base quantisation parameter for the frame. The final quantiser for a given block in a given plane is obtained from this value, possibly combined with {@code delta_qp} and the per-block delta in a manner documented for each type.

delta_qp: [[i32; 2]; 4]

Quantisation parameter offset from the base (per-frame) qp for a given plane (first index) and AC/DC coefficients (second index).
