class WebRtcRenderingTimelineMetric(telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric)
    WebrtcRenderingTimelineMetric calculates metric for WebMediaPlayerMS.
 
The following metrics are added to the results:
  WebRTCRendering_drift_time us
  WebRTCRendering_percent_badly_out_of_sync %
  WebRTCRendering_percent_out_of_sync %
  WebRTCRendering_fps FPS
  WebRTCRendering_smoothness_score %
  WebRTCRendering_freezing_score %
  WebRTCRendering_rendering_length_error %

Methods defined here:
AddResults(self, model, renderer_thread, interactions, results)
Adding metrics to the results.
__init__(self)

Static methods defined here:
IsMediaPlayerMSEvent(event)
Verify that the event is a webmediaplayerMS event.

Methods inherited from telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric:
AddWholeTraceResults(self, model, results)
Computes and adds metrics corresponding to the entire trace.
 
Override this method to compute results that correspond to the whole trace.
 
Args:
  model: An instance of telemetry.timeline.model.TimelineModel.
  results: An instance of page.PageTestResults.
VerifyNonOverlappedRecords(self, interaction_records)
This raises exceptions if interaction_records contain overlapped ranges.

Data descriptors inherited from telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric:
__dict__
dictionary for instance variables (if defined)
__weakref__
list of weak references to the object (if defined)
