VP8 is an open and royalty-free video compression format released by On2 Technologies in 2008.. Initially released as a proprietary successor to On2's previous VP7 format, VP8 was released as an open and royalty-free format in May 2010 after Google acquired On2 Technologies.
libvorbis – Lossy compression, implementation of the Vorbis format; developed by Xiph.Org Foundation. iLBC – Low bitrate compression, primarily voice; iSAC – Low bitrate compression, primarily voice; (free when using the WebRTC codebase) TTA – Lossless compression; WavPack – Hybrid lossy/lossless
Allows the user to adjust the balance between compression ratio and compression speed, without affecting the speed of decompression; LZO supports overlapping compression and in-place decompression. As a block compression algorithm, it compresses and decompresses blocks of data. Block size must be the same for compression and decompression.
Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...
A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .
lzop is a free software file compression tool which implements the LZO algorithm and is licensed under the GPL. Aimed at being very fast, lzop produces files slightly larger than gzip while only requiring a tenth of the CPU use and only slightly higher memory utilization. [2] lzop is one of the fastest compressors available, [3] a close second ...
