This sample demonstrates how to use the Windows.Media.Transcoding API to transcode a video file in a Windows Store app. . Transcoding is the conversion of a digital media file, such as a video or audio file, from one format to another. For example, you might convert a Windows Media file to MP4 so that it can be played on a portable device that supports MP4 format. Or, you might convert a high-definition video file to a lower resolution. In that case, the re-encoded file might use the same codec as the original file, but it would have a different encoding profile.
This sample covers the following scenarios:
- Converting a video file from one resolution to another resolution.
- Converting a video file using a custom output format.
- Creating a clip from a video using the TrimStart and TrimStop API.
Some of the transcode API covered in this sample are:
- Windows.Media.Transcoding
- MediaTranscoder
- MediaTranscoder.PrepareFileTranscodeAsync
- PrepareTranscodeResult
- PrepareTranscodeResult.TranscodeAsync
- MediaProperties.MediaEncodingProfile
- TrimStart
- TrimStop
