# msp_ENDPOINT_RTPFDX_ENABLE_SKEW_CALC

This video-specific structure enables or disables the calculation of skew values based on incoming RTCP sender reports and RTP packets for full-duplex and simplex receive endpoints. This structure is used for both audio and video endpoints.

Use this structure with the MSP_CMD_RTPFDX_CALC_SKEW_OFFSET command, which is described in Using RTCP for audio/video synchronization.

#### Definition

typedef struct {
U32 enable; // Set 4th bit to: 0=disable; 1=enable
} msp_ENDPOINT_RTPFDX_ENABLE_SKEW_CALC;

#### Field

Field name | Default | Description
--- | --- | ---
enable | 0 | Controls skew value calculations. Valid values are: 0 in 4th bit - Disables skew calculation. 1 in 4th bit - Enables skew calculation. Use the RTCP_ENABLE_RCV_SKEW_CALC macro to set the appropriate bit. For more information, see RTPRTCP_ENDPOINT_PARMS.
