Video4Linux (V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. [1] It supports USB webcams , TV tuners , CSI cameras, and related devices, standardizing their output, so programmers can easily add video support to their applications.
Turing – A High Efficiency Video Coding (HEVC/H.265) encoder implemented by BBC Research. libaom – Reference implementation for the royalty free AV1 video coding format by AOMedia, inheriting technologies from VP9, Daala and Thor. Kvazaar – An academic open-source encoder based on the High Efficiency Video Coding (HEVC/H.265) standard.
Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
Some containers only support a restricted set of video formats: DMF only supports MPEG-4 Visual ASP with DivX profiles. EVO only supports MPEG-4 AVC, MPEG-1 Video, MPEG-2 Video and VC-1. F4V only supports MPEG-4 AVC, MPEG-4 Visual and H.263. FLV only supports MPEG-4 Visual, VP6, Sorenson Spark and Screen Video. MPEG-4 AVC in FLV is possible ...

An example of vainfo output, showing supported video codecs for VA-API acceleration. The main motivation for VA-API is to enable hardware-accelerated video decode at various entry-points (VLD, IDCT, motion compensation, deblocking [5]) for the prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, H.265/HEVC, and VC-1/WMV3).
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
Some well-known examples of the code on demand paradigm on the web are Java applets, Adobe's ActionScript language for the Flash Player, and JavaScript. [1] The program code lies inactive on a web server until a user (client) requests a web page that contains a link to the code using the client's web browser.
