H.264 Codec SDK Libraries

Download

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 to MPEG-2.

H.264 Codec Libraries

In addition to the standard compression advantages that 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

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
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).
