Examples

The following example shows the call to the EndGetChunk(IAsyncResult) method and return of a ChunkResult object that contains the results data and indicates success or failure. For more information on this asynchronous scenario, see Timeline Markers and Events.

    foreach (TrackInfo trackInfo in streamInfo.SelectedTracks)
    {
        ChunkResult chunkResult = trackInfo.EndGetChunk(argAR);

        if (chunkResult.Result == ChunkResult.ChunkResultState.Succeeded)
        {
            System.Text.Encoding enc = System.Text.Encoding.UTF8;
            int length = (int)chunkResult.ChunkData.Length;
            byte[] rawData = new byte[length];
            chunkResult.ChunkData.Read(rawData, 0, length);
            String text = enc.GetString(rawData, 0, rawData.Length);
            TimelineMarker newMarker = new TimelineMarker();
            newMarker.Text = text;
            newMarker.Time = chunkResult.Timestamp;

            SmoothPlayer.Markers.Add(newMarker);
        }
    }
