Featuring LEAD's iCompress™ iCompress™ is a collection of technologies from LEAD's software development and research labs that have special relevance to digital imaging and multimedia application development software for both the enterprise and end users. These technologies represent 15 years of development in the programming tools marketplace. iCompress™ is a trademark of LEAD Technologies, Inc. Technologies!
The LEAD H.263 H.263 is an ITU standard, designed for low bitrate communications such as video-conferencing and video-telephony applications. At the same time it can be used for a wide range of bitrates and not just low bitrates. codec A COmpressor combined with a DECompressor, or encoder and a decoder, which allows you to both compress and decompress that same data. is a high quality lossy Compression techniques can be categorized into two groups, lossless and lossy. When data is compressed using a lossy compression technique, the result of the decompression will not exactly match the original. Most lossy compression techniques allow you to control how much loss (quality or q-factor). The following LEAD codecs offer lossy compression: H.264, H.263, MPEG/MPEG-2, MCMP/MJPEG, MJPEG2000 and MCMW interframe Interframe compressors compress the differences between adjacent frames. Generally, the interframe algorithms provide higher compression ratios than intraframe algorithms. The trade-off to the higher compression ratios of interframe compressions is speed. Inter-frame compressors usually can not compress video in real time, while intraframe compression can do real time compression. LEAD offers the following interframe compressors: H.264, H.263 and MPEG/MPEG-2 DirectShowÒ and Video for Windows (VfW) codec with a quality and compression ratio comparable to MPEG-4 This audio and video format is suitable for playback on Smartphones.. It can be used for a range of applications including video-conferencing, creating 3GPP This audio and video format is a low resolution format that is suitable for playbackon Smartphones and other cell phones. files (H.263 Video/AMR Audio) for playback on mobile phones, Internet video or surveillance and monitoring.
The LEAD H.263 codec is suitable for videos captured from cameras as well as video screen captures. This video codec registers into the Windows® collection of multimedia drivers and integrates with any application using DirectShow and Microsoft Video for Windows®. Existing video software, such as Windows® Media Player® and Ulead Media Studio® can utilize this codec to play, create, convert and edit.
All LEAD codecs and LEADTOOLS processing filters can be used from within any application supporting DirectShowÒ codecs and filters, and can also be controlled programmatically. This allows programmers to create powerful multimedia-based applications utilizing our extensive sets of compression and processing technologies. While it is possible to accomplish this using DirectShowÒ itself, the LEADTOOLS Multimedia SDK greatly simplifies the programming effort, allowing quick deployment of complex code.
The links below show easy-to-use examples of how to access LEADTOOLS codecs and processing filters programmatically:
