CanSeek to True to enable seeking and setting MediaSourceAttributesKeysDuration to the total duration of the clip; you derive that value from the product of FrameCount and FrameDuration You also populate the mediaStreamAttributes variable of type Dictionary <MediaStreamAttributeKeys,string> You include MediaStreamAttributeKeysHeight and MediaStreamAttributeKeysWidth and set them to the FrameHeight and FrameWidth, respectively You also set MediaStreamAttributeKeysCodecPrivateData to a blank string and MediaStreamAttributeKeysVideoFourCC to RGBA The four-character code indicates to the MediaElement that the frames are RGBA-style bitmaps and do not need any further decoding hence the blank string value for CodecPrivateData You then add a new MediaStreamDescription instance to the variable mediaStreamDescriptions, with the stream type set to MediaStreamTypeVideo and the attributes set to the just-initialized mediaStreamAttributes Note that you have only one media stream description entry, because you have only one stream: the video.

If you had additional streams, such as audio and script streams, you would have to add a description entry and related attributes for each of those streams You also initialize the mediaSampleAttributes dictionary to set the FrameHeight and FrameWidth respectively, although you do not need this variable until later Finally, you complete this method by calling ReportOpenMediaCompleted() and passing in the media source attributes and media stream descriptions Note that you call this method synchronously; but as discussed earlier, if the initialization process lasts longer than this process takes, you can easily return from OpenMediaAsync sooner and complete this task on a background thread At this point, the MediaElement begins calling GetSampleAsync() repeatedly to get samples to play GetSampleAsync() receives the MediaStreamType for the stream for which samples are being requested as a parameter.

To make referencing components easier, ZK also provides a Path utility class with which you can access any component within any ID space with an ID space directory format, just like accessing a file within a file system directory. For example, if you want to get the labelD component of this page, you can call Path.getComponent("/winA/labelD"). If

You first check to see if you are at the end of the file by comparing the lastFrame variable with MediaInfoFrameCount If frames remain to be sampled (lastFrame is currently not greater than MediaInfoFrameCount), you attempt to create a new instance of the MediaStreamSample class to represent the sample The following snippet shows the MediaStreamSample constructor:.

public MediaStreamSample(MediaStreamDescription mediaStreamDescription, Stream stream, long offset, long count, long timestamp, IDictionary<MediaSampleAttributeKeys, string> attributes) The MediaStreamSample constructor accepts a MediaStreamDescription instance as its first parameter Recall that in the implementation of OpenMediaAsync(), you returned instances of MediaStreamDescription to the MediaElement for each stream you handled The MediaStreamDescription instance that you supply to the MediaStreamSample constructor here must match the stream description values used earlier for the same stream As you can see in Listing 10-30, you use the same MediaStreamType and stream attributes dictionary in constructing this MediaStreamDescription instance that you used previously in OpenMediaAsync For the second parameter, stream, you pass in the actual media stream The third parameter, offset, is the byte offset into the stream where the MediaElement can begin reading this frame.

As you can in Listing 10-30, you derive this as the product of lastFrame and FrameSize: the total byte size of all the frames that have been read so far, further offset by the header size used to store the metadata block size at the beginning of the file The fourth parameter, count, is the number of bytes to be read to extract the frame that is, the value of the FrameSize variable The fifth parameter is an optional timestamp that you can associate with the sample; you pass in the starting point of this frame in time ticks calculated as the product of the frames read so far in lastFrame and FrameDuration The sixth and last parameter is the mediaSampleAttributes dictionary that you prepopulated in the OpenMediaAsync() method while initializing the media You then increment lastFrame and call ReportGetSampleCompleted, passing in the newly constructed MediaStreamSample instance.
