Currently there is no production ready HTML5 only solution for recording video over the web  The current available solutions are as follows   HTML Media Capture   Works on mobile devices and uses the OS  video capture app to capture video and upload POST it to a web server  You will get  mov files on iOS  these are unplayable on Android I ve tried  and  mp4 and  3gp on Android  At least the codecs will be the same  H 264 for video and AAC for audio in 99  of the devices     Image courtesy of https   addpipe com blog the-new-video-recording-prompt-for-media-capture-in-ios9   Flash and a media server on desktop    Video recording in Flash works like this  audio and video data is captured from the webcam and microphone  it s encoded using Sorenson Spark or H 264  video  and Nellymoser Asao or Speex  audio  then it s streamed  rtmp  to a media server  Red5  AMS  Wowza  where it is saved in  flv or  f4v files   The MediaStream Recording proposal     The MediaStream Recording is a proposal by the the Media Capture Task Force  a joint task force between the WebRTC and Device APIs working groups  for a JS API who s purpose is to make basic video recording in the browser very simple    Not supported by major browsers  When it ll get implemented  if it will  you will most probably end up with different filetypes  at least  ogg and  webm  and audio video codecs depending on the browser   Commercial solutions   There are a few saas and software  solutions out there that will handle some or all of the above including addpipe com  HDFVR  Nimbb and Cameratag   Further reading    HTML Media Capture video recording prompts in iOS9 HTML5 Video Recording covers both  HTML Media Capture and MediaStream Recording  Pipe is a saas for video recording that also handles the final conversion to  mp4

MediaRecorder API is the solution you are looking for  Firefox has been supporting it for some time now  and the buzz is is Chrome is gonna  implement it in its next release  Chrome 48   but guess you still might need to enable the experimental flag  apparently the flag won t be need from Chrome version 49  for more info check out this Chrome issue  Meanwhile  a sample of how to do it in Firefox   x000D   x000D  var video  reqBtn  startBtn  stopBtn  ul  stream  recorder  video   document getElementById  video    reqBtn   document getElementById  request    startBtn   document getElementById  start    stopBtn   document getElementById  stop    ul   document getElementById  ul    reqBtn onclick   requestVideo  startBtn onclick   startRecording  stopBtn onclick   stopRecording  startBtn disabled   true  ul style display    none   stopBtn disabled   true   function requestVideo       navigator mediaDevices getUserMedia         video  true        audio  true             then stm   gt          stream   stm        reqBtn style display    none         startBtn removeAttribute  disabled          video src   URL createObjectURL stream          catch e   gt  console error e       function startRecording       recorder   new MediaRecorder stream        mimeType   video mp4          recorder start      stopBtn removeAttribute  disabled      startBtn disabled   true      function stopRecording       recorder ondataavailable   e   gt        ul style display    block       var a   document createElement  a          li   document createElement  li        a download     video     new Date         slice 4  28     webm   join          a href   URL createObjectURL e data       a textContent   a download      li appendChild a       ul appendChild li          recorder stop      startBtn removeAttribute  disabled      stopBtn disabled   true    x000D   lt div gt      lt button id  request  gt      Request Camera    lt  button gt     lt button id  start  gt      Start Recording    lt  button gt     lt button id  stop  gt      Stop Recording    lt  button gt     lt ul id  ul  gt      Downloads List     lt  ul gt    lt  div gt   lt video id  video  autoplay gt  lt  video gt  x000D   x000D   x000D
