Detailed Description

Function Documentation

enableSendPcmStreamToRemote()

int com.portsip.PortSipSdk.enableSendPcmStreamToRemote	(	long	sessionId,
		boolean	state,
		int	streamSamplesPerSec
	)

Enable the SDK send PCM stream data to remote side from another source instead of microphone. This function MUST be called first to send the PCM stream data to another side.

Parameters

sessionId	The session ID of call.
state	Set to true to enable the send stream, or false to disable.
streamSamplesPerSec	The PCM stream data sample, in seconds. For example 8000 or 16000.

Returns

If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.

sendPcmStreamToRemote()

int com.portsip.PortSipSdk.sendPcmStreamToRemote	(	long	sessionId,
		byte []	data,
		int	dataLength
	)

Send the audio stream in PCM format from another source instead of audio device capturing (microphone).

Parameters

sessionId	Session ID of the call conversation.
data	The PCM audio stream data. It must be 16bit, mono.
dataLength	The size of data.

Returns

If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.

Remarks

Usually we should use it like below:

enableSendPcmStreamToRemote(sessionId, true, 16000);
     sendPcmStreamToRemote(sessionId, data, dataSize);

enableSendVideoStreamToRemote()

int com.portsip.PortSipSdk.enableSendVideoStreamToRemote	(	long	sessionId,
		boolean	state
	)

Enable the SDK to send video stream data to remote side from another source instead of camera.
This function MUST be called first to send the video stream data to another side.

Parameters

sessionId	The session ID of call.
state	Set to true to enable the send stream, or false to disable.

Returns

If the function succeeds, it will return value 0. If the function fails, it will return a specific error code.

sendVideoStreamToRemote()

int com.portsip.PortSipSdk.sendVideoStreamToRemote	(	long	sessionId,
		byte []	data,
		int	dataLength,
		int	width,
		int	height
	)

Send the video stream in i420 from another source instead of video device capturing (camera).
Before calling this function, you MUST call the enableSendVideoStreamToRemote function.

Parameters

sessionId	Session ID of the call conversation.
data	The video stream data. It must be in i420 format.
dataLength	The size of data.
width	The width of the video image.
height	The height of video image.

Returns

If the function succeeds, it will return value is 0. If the function fails, it will return a specific error code.
