The LEADTOOLS Multimedia product line incorporates DirectShow capture operations into ActiveX and COM objects that are easy to use in non-C compilers that support ActiveX or COM objects. The list of LEADTOOLS Multimedia Capture functionality includes:

• Support for WDM, native DirectShow including DV, and Video for Windows capture devices.
• Programmatically select the capture devices to use.
• Compress Audio streams and Video streams while capturing.
• Output compressed or uncompressed AVI, Windows Media content, WAVE and MPEG1Audio (MP3) formats.
• Capture directly to a file or save images individually to memory.
• Flicker-free video and audio preview during capture.
• Video preview supports zooming: (Fit to window, stretch, 50%, 75%, 100%, 200%, and full screen)
• Use the audio source built into the video device or a different audio source.
• Support for close captioning.
• Support for TV tuners.
• Support for multiple built-in configuration dialog boxes.
