Struct HardwareEncodeSession 

pub struct HardwareEncodeSession(/* private fields */);

The encode worker’s half of a hardware session.

Implementations

impl HardwareEncodeSession

pub fn selection(&self) -> &NativeVideoEncoderSelection

The encoder this session opened, reported the way every other export path reports the encoder it opened.

pub fn stage_timings(&self) -> EncodeStageTimings

Where this session’s time has gone, split the way the software sinks split theirs.

pub fn encode(&mut self, surface: &EncoderSurface) -> Result<(), EncodeError>

Submits surface and muxes whatever packets it produced.

Errors

Returns an adapter failure when the encoder rejects the frame or its packets cannot be written.

pub fn write_audio(&mut self, block: &AudioBlock) -> Result<(), EncodeError>

Buffers one audio block for the audio stream.

Errors

Returns an adapter failure for a format change, a non-monotonic block, or a failed audio encode.

pub fn finish(&mut self) -> Result<(), EncodeError>

Flushes the encoder and the audio, writes the trailer, and renames the output into place. Only this makes the output visible.

Errors

Returns an adapter failure from the flush, the trailer, or the rename.

pub fn abort(&mut self)

Discards the partial output.
