Working with metadata in AVI files Leave feedback

The GroupDocs.Metadata API supports extracting format-specific information from AVI file headers.

The following are the steps to read the header of an AVI file.

1. Load an AVI video
2. Get the root metadata package
3. Extract  the native metadata package using AviRootPackage.Header
4. Read the AVI header properties

AdvancedUsage.ManagingMetadataForSpecificFormats.Video.Avi.AviReadHeaderProperties

using (Metadata metadata = new Metadata(Constants.InputAvi))
{
	var root = metadata.GetRootPackage<AviRootPackage>();

	Console.WriteLine(root.Header.AviHeaderFlags);
	Console.WriteLine(root.Header.Height);
	Console.WriteLine(root.Header.Width);
	Console.WriteLine(root.Header.TotalFrames);
	Console.WriteLine(root.Header.InitialFrames);
	Console.WriteLine(root.Header.MaxBytesPerSec);
	Console.WriteLine(root.Header.PaddingGranularity);
	Console.WriteLine(root.Header.Streams);

	// ...
}

The AVI format is derived from the RIFF container which acts as a wrapper for various audio and video coding formats. As a derivative of RIFF, AVI files can be tagged with metadata in the INFO chunk. The chunk may include information such as the title of the work, the author, the creation date, and copyright information. Here is an example of how the RIFF INFO metadata can be extracted:

AdvancedUsage.ManagingMetadataForSpecificFormats.Video.Avi.AviReadInfoMetadata

using (Metadata metadata = new Metadata(Constants.InputAvi))
{
    var root = metadata.GetRootPackage<AviRootPackage>();
    if (root.RiffInfoPackage != null)
    {
        Console.WriteLine(root.RiffInfoPackage.Artist);
        Console.WriteLine(root.RiffInfoPackage.Comment);
        Console.WriteLine(root.RiffInfoPackage.Copyright);
        Console.WriteLine(root.RiffInfoPackage.CreationDate);
        Console.WriteLine(root.RiffInfoPackage.Software);
        Console.WriteLine(root.RiffInfoPackage.Engineer);
        Console.WriteLine(root.RiffInfoPackage.Genre);
 
        // ...
    }
}

GroupDocs.Metadata for .NET allows managing XMP metadata in AVI files. For more details please refer to the following guide: Working with XMP metadata.
