Hi all,


I am working with Player Framework 1.4, Adaptive Streaming Plugin 1.4, Timed Text Plugin 1.4 and Microsoft Smooth Streaming Client SDK Beta 2 for Windows 8 1.0. I play adaptive smooth streaming video. I need to send diagnistic information periodically to my backend server. What is needed: Bitrate, Download speed and Frame Per Sec. Have you get any idea, how to get this information from the player?


Thank you in advance!

Unfortunately, there isn't a way to get FPS from the media pipeline. However, you can get info about the currently selected track from the Smooth Streaming SDK:

adaptivePlugin = new AdaptivePlugin();
player.MediaLoading += player_MediaLoading;

void player_MediaLoading(object sender, MediaPlayerDeferrableEventArgs e)
    adaptivePlugin.Manager.AdaptiveSrcManager.AdaptiveSourceStatusUpdatedEvent += AdaptiveSrcManager_AdaptiveSourceStatusUpdatedEvent;

void AdaptiveSrcManager_AdaptiveSourceStatusUpdatedEvent(Media.AdaptiveStreaming.AdaptiveSource sender, Media.AdaptiveStreaming.AdaptiveSourceStatusUpdatedEventArgs args)
    switch (args.UpdateType)
        case AdaptiveSourceStatusUpdateType.BitrateChanged:
            var manifest = args.AdaptiveSource.Manifest;

            var videoStream = manifest.SelectedStreams.Where(i => i.Type == MediaStreamType.Video).FirstOrDefault();
            if (videoStream != null)
                var newBitrate = uint.Parse(args.AdditionalInfo);
                var track = videoStream.AvailableTracks.Where(t => t.Bitrate == newBitrate);
