ASF / WMV files indexing

Some WMV / ASF file do not have indexes. That cause seeking issues. You can use VisioForge.Tools.ASFIndexer class to index files.

​

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", VFWMIndexerType.FrameNumbers, 4000, VFWMIndexType.NearestDataUnit);
