The LEADTOOLS H.264 Codec is a state-of-the-art DirectShow filter
and Media Foundation Transform for compressing and decompressing
video data using H.264/AVC standard (ISO/IEC 14496-10). H.264 is
one of the most popular and advanced video standards developed
jointly by ITU and MPEG. H.264/AVC provides a far more efficient
algorithm for compressing video than most other compression
methods available. H.264 typically outperforms all existing
standards by a factor of three to four, especially in comparison
In addition to the standard compression advantages H.264 brings,
the LEADTOOLS implementation adds a proprietary "super compression"
option, even further increasing compression while still having
the ability to be decoded by standard H.264 decoders.
Full support for encoding, decoding, and transcoding H.264/AVC-compressed video data adhering to ISO/IEC 14496-10 standard
Decode and play high-definition 720i, 720p, 1080i, and 1080p formats in real time
Decode and encode with hardware acceleration for optimal speed
Intel Quick Sync Video
NVIDIA CUDA (NVENC & NVCUVENC)
Encode H.264 videos using both CUDA asynchronous and synchronous modes
Highly optimized to take advantage of multiple threads on multi-core machines
Achieves efficient compression by saving only the difference between motion vectors
Generate High, Main, and Baseline profiles for encoding onto Blu-ray media
Preset compression options for iPhone, iPod, and other devices and Smart Phones
Correct audio and video synchronization issues with automatic timestamp drift correction
Provides a mechanism for smoother playback of corrupted video data
User-defined motion estimation settings controls the balance between encoder speed and quality
Precise interprediction and network packet-loss protection achieved through multiple reference frames
Intraprediction may be performed either on 4x4 or 16x16 blocks
Efficient computation through Discrete Cosine Transform (DCT) as an integer transform
Motion vector prediction is performed before the frame is prepared for compression (pre-DCT), improving prediction and compression performance
Implements the SAD HADAMARD calculation to increase the compression ratio
Employs several contextual algorithms that improve both visual fidelity and compression ratios
Context-sensitive deblocking filter smooths out internal edges for improved visual quality
Context-Adaptive Variable Length Coding (CAVLC) to encode transform coefficients
Context-Adaptive Binary Arithmetic Coding (CABAC) method continually updates frequency statistics of the incoming data and adjusts the compression algorithm
Control the number and types of frames encoded into the video stream
Produce and consume RTP H.264 streams that work with video conferencing systems such as TANDBERG and Polycom
Use Windows Media Server to stream H.264 encoded video
Includes .NET (C# & VB) and C DLL libraries for 32 and 64-bit development
What is H.264?
H.264 is a high quality video compression algorithm and is suited for all types of applications
with different ranges of bit rates. In addition to MP4 files,
H.264 compressed video data can be stored inside AVI,
OGG, MPEG-2 Program,
MPEG2 Transport Stream,
MKV (Matroska), and MXF
files with the option of saving the file with or without the audio data. The technology is
also known as AVC (Advanced Video Coding) or MPEG-4 Part 10 (ISO/IEC 14496-10).

The LEADTOOLS Medical Multimedia Module includes the LEADTOOLS Multimedia SDK and a collection of state-of-the-art DirectShow filters and Media Foundation Transforms to compress and decompress video and audio data within DICOM files. This feature-rich product is designed to eliminate the complexity from converting multi-frame (cine) images and video streams to DICOM objects, including X-ray Angiography (XA), Ultrasound (US), Visible Light (VL), and Secondary Capture (SC). The LEADTOOLS Medical Multimedia Module utilizes the most advanced compression algorithms in the industry and approved by the DICOM standard, including MPEG-2, HD MPEG-2, Motion JPEG, Motion JPEG 2000, and H.264.
The LEADTOOLS Streaming Module is perfect for developers who need to stream audio and video over the Internet or corporate networks for a wide variety of applications. This module adds on to the LEADTOOLS Multimedia SDK and includes the Media Streaming Server, a high-level framework for implementing professional multimedia streaming servers that can stream any file to any device. The Streaming Module also provides a programmer-friendly set of peer-to-peer tools for creating video conferencing and security/surveillance applications. In addition to the SDK features, the Streaming Module bundles together several of LEAD's world-class audio and video codecs that will lower costs and improve user experience through reduced bandwidth requirements and high-quality playback.
The LEADTOOLS MPEG-2 Transport Module adds advanced MPEG-2 Transport and MPEG-2 Program streaming, playback, capture, and conversion capabilities to the LEADTOOLS Multimedia SDK. Developers can utilize robust UDP and TCP streaming with DVR and KLV metadata to create a wide spectrum of applications, including security systems, HDTV playback, and UAV ground stations.
NOTE: LEADTOOLS Video Codecs are very diverse and cover the gamut of multimedia features and technologies. Many codecs are included with the base SDK products above, while some can be added á la carte or bundled together with various add-on modules. See the Multimedia Product Comparison Chart for more details on how to obtain each video codec.
