Member Function Documentation

convert()

virtual int video::encode_session_t::convert ( platf::img_t & img )

pure virtual

Convert a captured frame into the encoder's required input representation.

Parameters

img	Captured image supplied by the platform display backend.

Returns

Zero when the frame was converted or imported successfully.

Implemented in video::avcodec_encode_session_t, and video::nvenc_encode_session_t.

invalidate_ref_frames()

virtual void video::encode_session_t::invalidate_ref_frames ( int64_t first_frame, int64_t last_frame )

pure virtual

Mark the frame range whose references must be invalidated.

Parameters

first_frame	First frame.
last_frame	Last frame.

Implemented in video::avcodec_encode_session_t, and video::nvenc_encode_session_t.

request_idr_frame()

virtual void video::encode_session_t::request_idr_frame ( )

pure virtual

Mark the frame as a request for an IDR frame.

Implemented in video::avcodec_encode_session_t, and video::nvenc_encode_session_t.

request_normal_frame()

virtual void video::encode_session_t::request_normal_frame ( )

pure virtual

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

Implemented in video::avcodec_encode_session_t, and video::nvenc_encode_session_t.
