Contoh
Contoh kode ini menunjukkan cara membaca metadata ASF asli.
using (Metadata metadata = new Metadata(Constants.InputAsf))
{
var root = metadata.GetRootPackage<AsfRootPackage>();
var package = root.AsfPackage;
// Menampilkan properti dasar
Console.WriteLine("Creation date: {0}", package.CreationDate);
Console.WriteLine("File id: {0}", package.FileID);
Console.WriteLine("Flags: {0}", package.Flags);
// Tampilkan Informasi Codec Asf
foreach (var codecInfo in package.CodecInformation)
{
Console.WriteLine("Codec type: {0}", codecInfo.CodecType);
Console.WriteLine("Description: {0}", codecInfo.Description);
Console.WriteLine("Codec information: {0}", codecInfo.Information);
Console.WriteLine(codecInfo.Name);
}
// Tampilkan deskriptor metadata
foreach (AsfBaseDescriptor descriptor in package.MetadataDescriptors)
{
Console.WriteLine("Name: {0}", descriptor.Name);
Console.WriteLine("Value: {0}", descriptor.Value);
Console.WriteLine("Content type: {0}", descriptor.AsfContentType);
AsfMetadataDescriptor metadataDescriptor = descriptor as AsfMetadataDescriptor;
if (metadataDescriptor != null)
{
Console.WriteLine("Language: {0}", metadataDescriptor.Language);
Console.WriteLine("Stream number: {0}", metadataDescriptor.StreamNumber);
Console.WriteLine("Original name: {0}", metadataDescriptor.OriginalName);
}
}
//Tampilkan properti aliran dasar
foreach (AsfBaseStreamProperty property in package.StreamProperties)
{
Console.WriteLine("Alternate bitrate: {0}", property.AlternateBitrate);
Console.WriteLine("Average bitrate: {0}", property.AverageBitrate);
Console.WriteLine("Average time per frame: {0}", property.AverageTimePerFrame);
Console.WriteLine("Bitrate: {0}", property.Bitrate);
Console.WriteLine("Stream end time: {0}", property.EndTime);
Console.WriteLine("Stream flags: {0}", property.Flags);
Console.WriteLine("Stream language: {0}", property.Language);
Console.WriteLine("Stream start time: {0}", property.StartTime);
Console.WriteLine("Stream number: {0}", property.StreamNumber);
Console.WriteLine("Stream type: {0}", property.StreamType);
//Menampilkan properti streaming audio
AsfAudioStreamProperty audioStreamProperty = property as AsfAudioStreamProperty;
if (audioStreamProperty != null)
{
Console.WriteLine("Audio bits per sample: {0}", audioStreamProperty.BitsPerSample);
Console.WriteLine("Audio channels: {0}", audioStreamProperty.Channels);
Console.WriteLine("Audio format tag: {0}", audioStreamProperty.FormatTag);
Console.WriteLine("Audio samples per second: {0}", audioStreamProperty.SamplesPerSecond);
}
//Tampilkan properti aliran video
AsfVideoStreamProperty videoStreamProperty = property as AsfVideoStreamProperty;
if (videoStreamProperty != null)
{
Console.WriteLine("Video bits per pixels: {0}", videoStreamProperty.BitsPerPixels);
Console.WriteLine("Compression: {0}", videoStreamProperty.Compression);
Console.WriteLine("Image height: {0}", videoStreamProperty.ImageHeight);
Console.WriteLine("Image width: {0}", videoStreamProperty.ImageWidth);
