- source
- IRandomAccessStream
The source stream.
source cannot be a InMemoryRandomAccessStream or other writeable stream.
- destination
- IRandomAccessStream
The destination stream.
- profile
- MediaEncodingProfile
The profile to use for the operation.
Returns
When this method completes, a PrepareTranscodeResult object is returned which can be used to start the transcode.
Examples
The following example shows how to use this method to transcode a stream.
var transcoder = new Windows.Media.Transcoding.MediaTranscoder();
return transcoder.prepareStreamTranscodeAsync(sourceStream, destinationStream, profile);
Remarks
The source parameter cannot be a InMemoryRandomAccessStream or other writeable stream.
