# ASF and WMV files indexing

Video Capture SDK .Net , Video Edit SDK .Net , Media Player SDK .Net

Platform: Windows

Some ASF and WMV files do not have indexes. That causes seeking issues. You can use VisioForge.Core.DirectShow.ASFIndexer class to index files.

# Sample code

C# sample usage:

var indexer = new ASFIndexer();
indexer.OnStop += delegate(object o, EventArgs args)
{
    MessageBox.Show("Indexing complete.");
};

indexer.OnError += delegate(object o, ErrorsEventArgs args)
{
    MessageBox.Show("Error during indexing: " + args.Message);
};

indexer.OnProgress += delegate(object o, ProgressEventArgs args)
{
    Debug.WriteLine("Indexing progress: " + args.Progress);
};

indexer.Start(@"c:\samples\sample.asf", WMIndexerType.FrameNumbers, 4000, WMIndexType.NearestDataUnit);
