Working with metadata in FLV files

Reading FLV header properties

The GroupDocs.Metadata API supports extracting format-specific information from the FLV file header.

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

1. Load an FLV video
2. Get the root metadata package
3. Extract  the native metadata package using the FlvRootPackage.getHeader method
4. Read the FLV header properties

try (Metadata metadata = new Metadata(Constants.InputFlv)) {
    FlvRootPackage root = metadata.getRootPackageGeneric();

    System.out.println(root.getHeader().getVersion());
    System.out.println(root.getHeader().hasAudioTags());
    System.out.println(root.getHeader().hasVideoTags());
    System.out.println(root.getHeader().getTypeFlags());
}
