Member Function Documentation

convert()

int video::nvenc_encode_session_t::convert ( platf::img_t & img )

inlineoverridevirtual

Encode one frame with NVENC and return the packet payload.

Parameters

img	Image or frame object to read from or populate.

Returns

Conversion status.

Implements video::encode_session_t.

encode_frame()

nvenc::nvenc_encoded_frame video::nvenc_encode_session_t::encode_frame ( uint64_t frame_index )

inline

Submit the next frame to NVENC and return the encoded payload.

Parameters

frame_index

Monotonic frame index assigned by the video pipeline.

Returns

Encoded NVENC frame payload and frame metadata.

invalidate_ref_frames()

void video::nvenc_encode_session_t::invalidate_ref_frames ( int64_t first_frame, int64_t last_frame )

inlineoverridevirtual

Mark the frame range whose references must be invalidated.

Parameters

first_frame	First frame.
last_frame	Last frame.

Implements video::encode_session_t.

request_idr_frame()

void video::nvenc_encode_session_t::request_idr_frame ( )

inlineoverridevirtual

Mark the frame as a request for an IDR frame.

Implements video::encode_session_t.

request_normal_frame()

void video::nvenc_encode_session_t::request_normal_frame ( )

inlineoverridevirtual

Mark the frame as a request for a normal inter frame.

Implements video::encode_session_t.
