Microsoft DirectShow is an extensible, filter-based framework, based on the Microsoft Windows Component Object Model (COM), that provides a common interface for mediaacross many of Microsoft's programming languages. Most video-related Windows applications, such as Microsoft's Windows Media Player, Winamp, and Windows Movie Maker, use DirectShow to manage multimedia content.

LEAD Elementary Stream Source Filter

Show in webframe

The LEAD Elementary Stream Source Filter is a DirectShow filter that can be used to merge multiple LTESC (LEADTOOLS Elementary Stream Catalog), or LTES (LEADTOOLS Elementary Stream) files into a single file. The input for this filter is created using the LEAD Elementary Stream Writer Filter. Together, these filters provide support for distributing the task of transcoding a single file across multiple computers.

This filter is responsible for merging the separate, transcoded files back into a single file. When an LTESC file is used as the source, this filter will parse the catalog for individual LTES files, merging them using the information stored in the catalog file. When an LTES file is used as the source, this filter will only convert the specified LTES file.

This filter supports the standard IFileSourceFilter interface. Use the IFileSourceFilter::Load method to let the LEAD Elementary Stream Source Filter know from where to read the data. Please see the Microsoft documentation for this interface for more information.
