## Detailed Description

The LinphoneCallStats objects carries various statistic informations regarding quality of audio or video streams.

To receive these informations periodically and as soon as they are computed, the application is invited to place a LinphoneCoreCallStatsUpdatedCb callback in the LinphoneCoreVTable structure it passes for instantiating the LinphoneCore object (see linphone_core_new() ).

At any time, the application can access last computed statistics using linphone_call_get_audio_stats() or linphone_call_get_video_stats().

## Field Documentation

int _LinphoneCallStats::type

Can be either LINPHONE_CALL_STATS_AUDIO or LINPHONE_CALL_STATS_VIDEO

jitter_stats_t _LinphoneCallStats::jitter_stats

jitter buffer statistics, see oRTP documentation for details

mblk_t* _LinphoneCallStats::received_rtcp

Last RTCP packet received, as a mblk_t structure. See oRTP documentation for details how to extract information from it

mblk_t* _LinphoneCallStats::sent_rtcp

Last RTCP packet sent, as a mblk_t structure. See oRTP documentation for details how to extract information from it

float _LinphoneCallStats::round_trip_delay

Round trip propagation time in seconds if known, -1 if unknown.

LinphoneIceState _LinphoneCallStats::ice_state

State of ICE processing.

LinphoneUpnpState _LinphoneCallStats::upnp_state

State of uPnP processing.

float _LinphoneCallStats::download_bandwidth
