HTMLVideoElementinterface provides special properties and methods for manipulating video objects. It also inherits properties and methods of
MediaDevices.getUserMedia()method prompts the user for permission to use one video and/or one audio input device such as a camera or screensharing and/or a microphone. If the user provides permission, then the returned
Promiseis resolved with the resulting
MediaStreamobject. If the user denies permission, or media is not available, then the promise is rejected with
NotFoundErrorrespectively. Note that it is possible for the returned promise to neither resolve nor reject, as the user is not required to make a choice.
MediaRecorder()constructor creates a new
MediaRecorderinterface of the MediaRecorder API provides functionality to easily record media. It is created by the invocation of the
MediaRecorder.isMimeTypeSupported()method returns a
truethat indicates whether the value of the argument is one the user agent can record.
MediaRecorder.onpauseevent handler (part of the MediaRecorder API) handles the
pauseevent, allowing you to run code in response to the media recording being paused.
appendWindowEndproperty of the
SourceBufferinterface controls the timestamp for the end of the append window, a timestamp range that can be used to filter what media data is appended to the
SourceBuffer. Coded media frames with timestamps wthin this range will be appended, whereas those outside the range will be filtered out.
modeproperty of the
SourceBufferinterface controls whether media segments can be appended to the
SourceBufferin any order, or in a strict sequence.
<video>elements provide support for playing audio and video media without requiring plug-ins. Video codecs and audio codecs are used to handle video and audio, and different codecs offer different levels of compression and quality. A container format is used to store and transmit the coded video and audio (both together, the case of a video with a soundtrack). Many combinations of codecs and container formats exist, although only a handful of these are relevant on the Web.
