Multimedia DirectShow Filters

The LEADTOOLS Multimedia SDK includes a fully enabled development license for many components, as well as evaluation versions of several optional filters and video/audio codecs. You may consider licensing these for inclusion with your multimedia application to add value to your product. For instructions on licensing any of the DirectShow filters described below, see the Licensing section of the help file or contact oemsales@leadtools.com . Evaluation versions are noted as such in the Feature column.

Video Add

LMVAdd.DLL - ILMVAdd, ILMVAddDisp

ILMVAdd.h

The add filter can be used for enhancing night vision or dropping more light on dark sources to clarify objects. The effect is performed in 2 ways, the first yields a frame rate divided by the number of added frames, while the other almost preserves the frame rate by using previous frames to output each sample. The output is of course not the same from the two methods. The filters functionality is exposed through both user and programming interfaces.

ISO Multiplexer**

LMISOMux.DLL DSKernel2.DLL

 

The LEAD ISO Multiplexer can be used to create files based on the ISO base file format described in ISO/IEC 14496-12. The ISO base file format should not be confused with the files used to store CD images or DVD images (which have the .ISO extension).

The LEAD ISO Multiplexer does not support every video and audio compression. The following compressions are supported:

  • MPEG-4 (MPEG-4 Part 2) video compression
  • H.264 (MPEG-4 Part 10) video compression
  • AAC audio compression
  • (PCM) uncompressed audio

MPEG-2 Multiplexer*

LMMpg2Mx2.DLL DSKernel2.DLL

 

The LEAD MPEG-2 Multiplexer can be used to create MPEG-2 Program files.

The following audio compressions are supported:

  • MPEG-1 Audio compression (Layer 2 or Layer 3)
  • AC3 Audio compression (preferred audio compression for DVD)
  • AAC Audio compression using ADTS headers.
  • LPCM Audio format (uncompressed audio used for DVD)

The following video compressions are supported:

  • MPEG-2 Video Compression
  • MPEG-4 Part 2 Video Compression
  • H.264 (AVC, MPEG-4 Part 10) Video Compression

There are two main reasons to create MPEG-2 Program files:

  1. To create MPEG-2 files for file interchange purposes. In this case, it is recommended to use the LEAD MPEG Audio Encoder and LEAD MPEG2 Video Encoder to compress the data.
  2. To create MPEG-2 files for creating a DVD out of them. In this case, we recommend you to use the LEAD AC3 Audio Encoder and LEAD MPEG2 Video Encoder to compress the data.
