Detailed Description

Function Documentation

setAudioRtcpBandwidth:BitsRR:BitsRS:KBitsAS:()

- (int) setAudioRtcpBandwidth:		(long)	sessionId
BitsRR:		(int)	BitsRR
BitsRS:		(int)	BitsRS
KBitsAS:		(int)	KBitsAS

Set the audio RTCP bandwidth parameters as the RFC3556.

Parameters

sessionId	The session ID of call conversation.
BitsRR	The bits for the RR parameter.
BitsRS	The bits for the RS parameter.
KBitsAS	The Kbits for the AS parameter.

Returns

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

setVideoRtcpBandwidth:BitsRR:BitsRS:KBitsAS:()

- (int) setVideoRtcpBandwidth:		(long)	sessionId
BitsRR:		(int)	BitsRR
BitsRS:		(int)	BitsRS
KBitsAS:		(int)	KBitsAS

Set the video RTCP bandwidth parameters as the RFC3556.

Parameters

sessionId	The session ID of call conversation.
BitsRR	The bits for the RR parameter.
BitsRS	The bits for the RS parameter.
KBitsAS	The Kbits for the AS parameter.

Returns

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

setAudioQos:DSCPValue:priority:()

- (int) setAudioQos:		(BOOL)	enable
DSCPValue:		(int)	DSCPValue
priority:		(int)	priority

Set the DSCP (differentiated services code point) value of QoS (Quality of Service) for audio channel.

Parameters

enable	Set to true to enable audio QoS.
DSCPValue	The six-bit DSCP value. Valid value ranges 0-63. As defined in RFC 2472, the DSCP value is the high-order 6 bits of the IP version 4 (IPv4) TOS field and the IP version 6 (IPv6) Traffic Class field.
priority	The 802.1p priority (PCP) field in an 802.1Q/VLAN tag. Values 0-7 indicate the priority, while value -1 leaves the priority setting unchanged.

Returns

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

setVideoQos:DSCPValue:()

- (int) setVideoQos:		(BOOL)	enable
DSCPValue:		(int)	DSCPValue

Set the DSCP (differentiated services code point) value of QoS (Quality of Service) for video channel.

Parameters

enable	Set as true to enable QoS, or false to disable.
DSCPValue	The six-bit DSCP value. Valid value ranges 0-63. As defined in RFC 2472, the DSCP value is the high-order 6 bits of the IP version 4 (IPv4) TOS field and the IP version 6 (IPv6) Traffic Class field.

Returns

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

setVideoMTU:()

- (int) setVideoMTU:

(int)

mtu

Set the MTU size for video RTP packet.

Parameters

mtu	Set MTU value. Allowed value ranges 512-65507. Other values will be automatically changed to the default 1400.

Returns

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