HTTP Live Streaming. HTTP Live Streaming (also known as HLS) is an HTTP -based adaptive bitrate streaming communications protocol developed by Apple Inc. and released in 2009. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers. As of 2022, an annual video industry survey has ...
License. MPEG LA [ 1 ] Website. www.itu.int /rec /T-REC-H.264. Block diagram of video coding layer of H.264 encoder with perceptual quality score. Advanced Video Coding (AVC), also referred to as H.264 or MPEG-4 Part 10, is a video compression standard based on block-oriented, motion-compensated coding. [ 2 ]
Adaptive bitrate streaming works by detecting a user's bandwidth and CPU capacity in real time, adjusting the quality of the media stream accordingly. [2] It requires the use of an encoder which encodes a single source media (video or audio) at multiple bit rates. The player client [3] switches between streaming the different encodings ...
In April 2010, the x264 project announced full Blu-ray compliant video encoding capability making x264 the first free Blu-ray compliant software H.264 encoder. [17] x264 has always had the ability to create video streams that are playable on most Blu-ray devices. However, it was up to the user to choose appropriate conversion settings.
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.

VP9 is the last official iteration of the TrueMotion series of video formats that Google bought in 2010 for $134 million together with the company On2 Technologies that created it. The development of VP9 started in the second half of 2011 under the development names of Next Gen Open Video (NGOV) and VP-Next. [8][9][10] The design goals for VP9 ...
Total algorithmic delay for an audio format is the sum of delays that must be incurred in the encoder and the decoder of a live audio stream regardless of processing speed and transmission speed, such as buffering audio samples into blocks or frames, allowing for window overlap and possibly allowing for noise-shaping look-ahead in a decoder and ...
