FEC was used during the call. v2:OpaqueAudioData<103> v2:OpaqueAudioDataType No Not used. v3:AudioPostFECPLR<104> xs:float No Reports packet loss rate after FEC has been applied for audio. Value between 0.00 and 1.00. Percentage v2:Separator<105> default No Separator element used for future schema extensions. Not applicable v3:DecodeStereoPercent <106> xs:float Yes Percentage of audio decoded as stereo. Percentage v3:AecRenderStereoPercent<107> xs:float Yes Percentage of call processed by AEC as stereo render. Percentage v3:EncodeStereoPercent <108> xs:float Yes Percentage of audio encoded as stereo. Percentage v3:AecCaptureStereoPercent <109> xs:float Yes Percentage of call processed by AEC as stereo capture. Percentage v3:Separator3<110> default No Separator element used for future schema extensions. Not applicable v4:JitterBufferSizeAvg<111> xs:int Yes Average size of jitter buffer during session. milliseconds v4:JitterBufferSizeMax<112> xs:int Yes Maximum size of jitter buffer during session. Milliseconds v4:JitterBufferSizeMin<113> xs:int Yes Minimum size of jitter buffer during session. Milliseconds
VideoBitRateAvg xs:int Yes Average bit rate, or bits per second, sent or received for a video , computed over the duration of the . This includes raw video and transport bits. Bits per second VideoBitRateMax xs:int Yes Maximum bit rate, or bits per second, sent or received for a video stream (2), computed over the duration of the session. Bits per second VideoFrameRateAvg xs:float Yes Average frames per second sent or received for a video stream (2), computed over the duration of the session. Frames per second VideoPacketLossRate xs:float Outbound The average fraction lost, as specified in section 6.4.1, computed over the duration of the session. Fraction VideoFrameLossRate xs:float Inbound The average fraction of frames lost on the video receiver side, computed over the duration of the session. Fraction VideoFrameEncodingTime Outbound Average encoding time. This is the time difference between encoding start and encoding finish, computed over the duration of the session. Milliseconds VideoFrameDecodingTime xs:float Inbound Average frame decoding time. This is the time difference between decoding start and decoding finish, computed over the duration of the session. Milliseconds VideoFEC xs:boolean No Not used. Not applicable FrozenVideoFreq xs:float Inbound Frequency of occurrence of long duration frozen video, where long duration is defined as no video frames displayed for more than 1 second. Equal to the ratio of total occurrence over session duration. Fraction Inbound Percentage of total duration for which frozen video was observed. Percentage xs:float Inbound Average number of consecutive packets lost during a video session. Packets RateMatchLevel<151> Outbound Describes the level of frame rate matching in video sessions. This is the average of the level values Not applicable <150>
Reordering extent is defined by section 4.2. v4: xs:int Inbound Maximum late time offset of received reordered packets in 100ns units. Late time offset is defined by [RFC4737] section 4.3. v4: xs:int Inbound Total video packets received by the network, but discarded because they arrived too late relative to other packets, due to high network jitter. Packets v4:Separator4<188> default No Separator element used for future schema extensions. Not applicable v3:SendCodecTypes Element This is filled by the codec name, as specified in section 3.1.5.3 or section 6 concatenated by a string that describes the type of codec resource used.<189> The codec resource choices for outbound direction (that is, encoding) are as follows: Type String Description Software SW Software encoding integrated in app, running on CPU. Inbox Software SWI Software encoding using Operating System component, running on CPU. Hardware HW Hardware encoding integrated in app, running on DSP or dedicated hardware. Hardware HWI Hardware encoding using Operating System component, running on DSP or dedicated hardware. Camera CAM H.264 encoding camera. Example: For the H264 codec, if a portion of the call is HW but then the application switches to SW, then v3:SendCodecTypes element will be filled with "H264 SW-HW". v3:RecvCodecTypes Element This is filled by the name, as specified in section 3.1.5.3 or section 6 concatenated by a string that describes the type of codec resource used. <190> The codec resource choices for inbound direction (that is, decoding) are as follows: Type String Description Software SW Software decoding integrated in app, running on CPU. Inbox Software SWI Software decoding using Operating System component, running on CPU.
