H.264 Coding Standard

Thumbnails

Produces a series of JPEG thumbnails 5 seconds apart, 300 pixels wide. The height is determined by the source frame size.

Use this preset name to generate a series of thumbnails for use in Xbox Live Applications. For information about providing a custom configuration file, see Task Preset for Thumbnail Generation.

The following method uses LINQ to Entities to find the latest version of the media processor based on the specified name.

private static IMediaProcessor GetLatestMediaProcessor(string mediaProcessorName)
{
    // The possible strings that can be passed into the 
    // method for the mediaProcessor parameter:
    //   Windows Azure Media Encoder
    //   Windows Azure Media Packager
    //   Windows Azure Media Encryptor
    //   Storage Decryption

    var processor = _context.MediaProcessors.Where(p => p.Name == mediaProcessorName).
        ToList().OrderBy(p => new Version(p.Version)).LastOrDefault();

    if (processor == null)
        throw new ArgumentException(string.Format("Unknown media processor", mediaProcessorName));

    return processor;
}

The following code calls the GetLatestMediaProcessor method.

IMediaProcessor processor = GetLatestMediaProcessor("Windows Azure Media Encoder");
