Struct _VAEncMiscParameterHRD 

#[repr(C)]
pub struct _VAEncMiscParameterHRD {
    pub initial_buffer_fullness: u32,
    pub buffer_size: u32,
    pub va_reserved: [u32; 4],
}

HRD / VBV buffering parameters for encoding.

This sets the HRD / VBV parameters which will be used by the rate controller for encoding. It should be specified in modes using a bitrate target when the buffering of the output stream needs to be constrained.

If not provided, the encoder may use arbitrary amounts of buffering.

Fields

initial_buffer_fullness: u32

The initial fullness of the HRD coded picture buffer, in bits.

This sets how full the CPB is when encoding begins - that is, how much buffering will happen on the decoder side before the first frame. The CPB fullness will be reset to this value after any rate control reset (a change in parameters or an explicit reset).

For H.264, it should match the value of initial_cpb_removal_delay in buffering_period SEI messages.

buffer_size: u32

The HRD coded picture buffer size, in bits.

For H.264, it should match the value of cpb_size_value_minus1 in the VUI parameters.

va_reserved: [u32; 4]

\brief Reserved bytes for future use, must be zero

Trait Implementations

impl Clone for _VAEncMiscParameterHRD

fn clone(&self) -> _VAEncMiscParameterHRD

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for _VAEncMiscParameterHRD

impl Debug for _VAEncMiscParameterHRD

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for _VAEncMiscParameterHRD

fn default() -> _VAEncMiscParameterHRD

Returns the “default value” for a type.

impl Eq for _VAEncMiscParameterHRD

impl PartialEq for _VAEncMiscParameterHRD

fn eq(&self, other: &_VAEncMiscParameterHRD) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
