Both properties are enabled for change notification. The FrameRate property defaults to 24. In the property setter for the FrameRate property, you use TimeCode.ParseFrameRate() to check whether the FrameRate is one of the known frame rates and throw an exception if not. As we mentioned earlier in this recipe, Silverlight has no built-in mechanism to extract frame rates. So, in the sample, this always defaults to 24. However, if you devise another mechanism to acquire the frame rate of the video (maybe from a content-management back end that can supply the frame rate through a web service), you can set this property to some other value. The SMPTETimeCode property defaults to a string representing the timecode at the start of the video. It is bound to tbxSMPTETimeCode in the XAML to display the timecode. Because that binding is TwoWay, it can also accept user edits. In the property setter, you validate any user input to make sure it is in the valid timecode format using the TimeCode.ValidateSmpte12MTimeCode() static method. If the format is invalid, you raise an exception, which is then displayed as a validation error using the binding validation mechanism.

Recall from Recipe 10-2 that the sample uses a DispatcherTimer named PlayProgressUpdate to raise DispatcherTime.Tick events at regular intervals while the video is playing. PlayProgressUpdate_Tick() handles the Tick event and changes Slider.Value to cause the slider thumb to move. You now set the PlayProgressUpdate.Interval property to the duration of a single frame, so that the Tick even fires at each frame interval. You do this once initially in the MediaSlider constructor as well as in the property setter of the FrameRate property. In the PlayProgressUpdate_Tick() handler method, you update the SMPTETimeCode property to the current timecode using the TimeCode.FromTicks() static function; this function accepts the current MediaElement.Position as CPU ticks and the current frame rate, and returns a TimeCode instance. You convert this to a string before you set the property. Because SMPTETimeCode is bound to tbxSMPTETimeCode, this updates the UI with the timecode as the video plays. You also handle the PropertyChanged event of the MediaSlider control. Because the SMPTETimeCode property is TwoWay bound to tbxSMPTETimeCode, the PropertyChanged event on the control is fired when the user edits the value in tbxSMPTETimeCode, causing a change in value to MediaSlider.SMPTETimeCode. In the MediaSlider_PropertyChanged() handler, you ensure that you are handling the correct property change. You also make sure the media is currently paused. You then set the position of the media to the usersupplied timecode. To do so, you construct a new TimeCode instance, using a constructor that accepts a string-formatted timecode value that you get from MediaSlider.SMPTETimeCode, and the current frame rate parsed into a SmpteFrameRate enumerated value. When you have the new TimeCode instance, you construct a TimeSpan from the TimeCode.Duration property, which reflects the total number of whole and fractional seconds in that timecode, and use that to set the current position of the media.

You want to use Silverlight to play a media file whose storage format and/or encoding scheme is not supported by Silverlight directly.
