FFmpeg is part of the workflow of many other software projects, and its libraries are a core part of software media players such as VLC, and has been included in core processing for YouTube and Bilibili. [10] Encoders and decoders for many audio and video file formats are included, making it highly useful for the transcoding of common and ...
The HEVC MainConcept SDK encoder was demonstrated at the IBC 2012 trade show. [8] [9] On September 9, 2012, ATEME demonstrated at the IBC 2012 trade show a HEVC encoder that encoded video with a resolution of 3840x2160p at 60 fps with an average bit rate of 15 Mbit/s. [10] [11] ATEME is planning to release their HEVC encoder in October 2013 ...
] Xiph developers compared the 1.1 Theora encoder to YouTube's H.264 and H.263+ encoders, in response to concerns raised in 2009 about Theora's inferior performance by Chris DiBona, a Google employee. [48] They found the results from Theora to be nearly the same as YouTube's H.264 output, and much better than the H.263+ output. [49] [50]
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
AVC-LongG enables compression of video resolutions up to 1920 × 1080 @ 23.97, 25 and 29.97p, with 10 bits of pixel depth at 4:2:2 color sampling, at data rates as low as 25 Mbit / sec. [7] More over, the AVC-Intra Class 50/100 is now extended to Class 200 and Class 4:4:4.
Microsoft Expression Encoder [6] (formerly Expression Media Encoder) is a discontinued [7] transcoding and non-linear video editing software application for Microsoft Windows. It can create video streams for distribution via Microsoft Silverlight. This utility is created to record the screen for various purposes such as YouTube, Twitch etc.
For any particular encoder, the pulse width and phase difference ranges are defined by "symmetry" and "phase" (or "phasing") specifications, respectively. For example, in the case of an encoder with symmetry specified as 180° ±25°, the width of every output pulse is guaranteed to be at least 155° and no more than 205°.
Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression.
