Struct dynlink_nvidia_encode::api::Encoder

pub struct Encoder<'lib> { /* private fields */ }

The lifetime ’lib refers to the shared library.

Implementations

impl<'lib> Encoder<'lib>

pub fn get_encode_guid_count(&self) -> Result<u32, NvencError>

pub fn get_encode_preset_config( &self, encode: GUID, preset: GUID ) -> Result<EncodeConfig, NvencError>

pub fn initialize(&self, init_params: &InitParams) -> Result<(), NvencError>

pub fn alloc_input_buffer( self_: &Rc<Self>, width: u32, height: u32, format: BufferFormat ) -> Result<InputBuffer<'lib>, NvencError>

Allocate a new buffer managed by NVIDIA Video SDK

pub fn alloc_output_buffer( self_: &Rc<Self> ) -> Result<OutputBuffer<'lib>, NvencError>

pub fn encode_picture( &self, input: &InputBuffer<'_>, output: &OutputBuffer<'_>, pitch: usize, pts: Duration ) -> Result<(), NvencError>

Main entry to encode a video frame with a given presentation time stamp.

Note that since enablePTD is true, this may return NV_ENC_ERR_NEED_MORE_INPUT which should not be treated as a fatal error.

pub fn end_stream(&self) -> Result<(), NvencError>

End the encoder stream

According to the nvenc docs, this can be called multiple times.

pub fn get_sequence_parameter_sets(&self) -> Result<Vec<u8>, NvencError>

Trait Implementations

impl<'lib> Drop for Encoder<'lib>

fn drop(&mut self)

Executes the destructor for this type.
