Detailed Description

An encoder for video frames.

An encoder can encode video frames into raw encoded packets.

Member Function Documentation

Create()

static std::unique_ptr< Encoder > Create ( const CodecConfig & codecConfig )

inlinestatic

Creates an encoder with a given configuration.

Parameters

[in]

codecConfig

The configuration.

Returns

A pointer to a encoder object.

Exceptions

Any	exception derived from std::exception including CvbException.

As encoders may use exclusive system resources the number of encoders active simultaneously is often limited to one.

Encode()

CodecStatus Encode ( const Frame & frame )

inline

Encode a video frame.

Parameters

[in]

frame

The video frame to encode.

Returns

A the status of the encoder.

Exceptions

Any	exception derived from std::exception including CvbException.

Encoders will usually deliver packets only after a few frames have been encoded. If no packets are received the encoder will refuse to take new frames and return ReadoutRequired.

Flush()

void Flush ( )

inline

Flush the encoder and finish encoding.

Exceptions

Any	exception derived from std::exception including CvbException.

Notify the encoder that no more frames will be send, so the remaining packets can be delivered. The encoder will not accept any more frames after flushing.

ReceivePacket()

std::unique_ptr< Packet > ReceivePacket ( )

inline

Receive an encoded packet.

Returns

A pointer to the packet object (may be empty).

Exceptions

Any	exception derived from std::exception including CvbException.

Encoders will usually deliver packets only after a few frames have been encoded. If no new packets can be received this method will return empty pointers.
