Detailed Description

Function Documentation

enableSendPcmStreamToRemote:state:streamSamplesPerSec:()

- (int) enableSendPcmStreamToRemote:		(long)	sessionId
state:		(BOOL)	state
streamSamplesPerSec:		(int)	streamSamplesPerSec

Enable the SDK to send PCM stream data to remote side from another source instead of microphone.

Parameters

sessionId	The session ID of call.
state	Set to true to enable the sending 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.

Remarks

To send the PCM stream data to another side, this function MUST be called first.

sendPcmStreamToRemote:data:()

- (int) sendPcmStreamToRemote:		(long)	sessionId
data:		(NSData *)	data

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 in 16bit, mono.

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:

[myVoIPSdk enableSendPcmStreamToRemote:sessionId state:YES streamSamplesPerSec:16000];
[myVoIPSdk sendPcmStreamToRemote:sessionId data:data];

enableSendVideoStreamToRemote:state:()

- (int) enableSendVideoStreamToRemote:		(long)	sessionId
state:		(BOOL)	state

Enable the SDK to send video stream data to remote side from another source instead of camera.

Parameters

sessionId	The session ID of call.
state	Set to true to enable the sending 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:data:width:height:()

- (int) sendVideoStreamToRemote:		(long)	sessionId
data:		(NSData *)	data
width:		(int)	width
height:		(int)	height

Send the video stream to remote side.

Parameters

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

Returns

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

Remarks

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.
Usually we should use it like below:

[myVoIPSdk enableSendVideoStreamToRemote:sessionId state:YES];
[myVoIPSdk sendVideoStreamToRemote:sessionId data:data width:352 height:288];
