Detailed Description

The video source provides all video frames to the encoder for transmission over the socket.

A video source expects

Method Documentation

attatchRecorder:

- (void) attatchRecorder:

(FileWriter *)

fileWriter

Records captured data to local device

configureSession:

- (void) configureSession:

(AVCaptureSession *)

session

Initialize the VideoSource with the appropriate inputs

Parameters

session

Session to initialize

encodeWithBlock:onParams:

- (void) encodeWithBlock:		(source_handler_t)	block
onParams:		(source_param_handler_t)	paramsHandler

Setup the encoding handler. Will pass the handles to the encoder for processing the data

Parameters

block	data and timestamp of the frame to process
paramsHandler	parameters of the encoding used for setting up the codec

getSourceProperties

- (NSDictionary *) getSourceProperties

A dictionary formatted with the following keys:

• R5VideoWidthkey - NSNumber (int)
• R5VideoHeightKey - NSNumber (int)
• R5VideoBitRateKey - NSNumber (int)
• R5VideoOrientationKey - NSNumber (float)
• R5VideoAdaptiveBitRateKey - NSString ( "YES" | "NO" )

Returns

a properly formatted dictionary with all keys set

releaseSession:

- (void) releaseSession:

(AVCaptureSession *)

session

Release the session and stop all session activities

Parameters

session

Session to stop

startVideoCapture

- (void) startVideoCapture

Start capturing and encoding video

stopVideoCapture

- (void) stopVideoCapture

Stop capturing and encoding video

Property Documentation

orientation

- (int) orientation

readwriteatomic

Orientation of presentation.

Note

Video is rotated by the streaming software and NOT in the encoding. This is a meta flag only.
