I have a lot of developers interested in this one.

Use case: video editing or photobooth app that allows you to capture yourself, do something crazy
(apply webgl filters), upload to youtube, and share out to G+.

This will also be very interesting once issue 112404 is implemented.

This is on our to-do-list, but in our mind the API is not really ready to be implemented yet. For more details:

Marcin, are any of those issues in that email you linked important enough to prevent preliminary implementation?

Is there any way to increase the priority of this beyond getting more people to star it?

This is critical ask for schools who are looking for screencasting apps which will allow recording of video, audio so as to create a flipped classroom

More info

As we look to go to a 1:1 environment, we are also wanting teachers to implement a "flipped classroom" approach. So teachers would supply most of the lecturing and materials to the students ahead of time as homework. 

Teachers need to capability to record their actions on the screen and their voice. The teacher would show what to do on the screen and talk how to do it. We would then want to export that video so we could host it somewhere.

Students could also record themselves showing how they completed a problem. This allows the students to become teachers, which is another characteristic of the flipped classroom.

Teachers and students would like to record themselves using the webcam and audio. This would allow teachers to record lectures and would allow students to create vodcasts. Again we would need to export when done.

My use case is similar: for educators to easily record audio narrations to store on a server for later playback by their students. Would be fantastic to do this with MediaStreamRecorder rather than flash. 
Comment 8 by, Apr 14 2012
Very similar case here, too - currently using Flash to allow students to record vocal responses and submit them for assignments, and would love to be able to do it with MediaStreamRecorder instead of Flash.
Most interested in ability to record audio, too. Could unlock a lot of scenarios not doable today without plugins- recording voice clips to share to Twitter, recording voice comments in collaboration apps, saving voice clip and also sending to speech translator service for transcript. Hope this sees progress soon.
Also very interested in ability to record audio.  Access either to raw PCM data would be great, and access to different encoded formats such as speex would be even better.  But would be very happy to be able to get raw audio data at different bit rates.

Just so you know, MediaStreamRecorder is currently not described in the spec:

Hopefully it will be added back in a better shape than prev version.
Comment 13 by, Jun 4 2012
It is in the latest public version of the spec:

+1 to this feature, I am very interested in seeing it implemented.
Yeah right, should have written the editor's draft. The first version wasn't really ready to be implemented ( This is a step towards getting a better spec in place.

You don't need MediaStreamRecorder to record audio with the current spec.

But, you DO need to star this issue:

And what is going on at ? "In chrome 19 there is no PeerConnection, in chrome 20 there is no MediaStream" ... "Chrome Canary Version 21.0.1150.0 canary: I couldn't see the "Enable MediaStream"
The mediastream flag is dropped from the setting since it's now on by default. You still need to enable PeerConnection flag though.

moved from being a bug to a feature request.
Issue 142638 has been merged into this issue.
We are working on a PhotoBooth application built entirely in JavaScript (No NaCl) and this is an absolute "must have" for us.  We have a current workaround, but there is a 200ms or so lag.  In order for us to deliver "desktop quality" performance, we need this feature.

You can already record audio input with getUserMedia(), the Web Audio API, and the File API
Comment 37 by Deleted ...@, Oct 29 2012
Comment 39 by, Nov 6 2012
Is it possible to record short videos with getUserMedia() and the File API?
Please plugin
googuy, yes. See my demo at
It's only a proof of concept though. The processing time for anything over a few seconds of video starts to get long.
Comment 42 by, Nov 6 2012
I'm aware of this method.
It's very clever but it needs a lot of processing and lacks audio.

Implementing MediaStreamRecorder could be easier to use.

For WebRTC you need to implement some video and audio encoding so why not use that same native encoder to record the stream.
Hi, the last version of Google Chrome: 23.0.1271.64 m, in chrome://flags/ the last option allow enable record the audio input with getUserMedia()

Any demo that implement audio and video send to stream to other browser, with peerconnection?
any progress on saving recorded audio generated from the getusermedia?

The spec is still being written. Latest draft is here:

Please provide feedback.
Comment 85 by, Jan 30 2013
We need this api to be implemented asap!!!!
We need Video + Audio to be recorded and SAVED to storage together!! This stops me to use the HTML5 media API and pull me back to the dirty Flash!!

а чего мы ждем то ???))))

Здравствуйте! Я была бы рада, если бы ввели в приложении видео и аудиописьма или аудио, да и которые будут работать без встроенных плагинов (Flash, Silverlight, etc...). Это бы дало возможность использовать приложение на менее мощных устройствах. Было бы хорошо, если для мобильных такое приложение было. С ним легко работать, оно удобно и работает быстро в реальном времени. Жаль только то, что время последнего визита собеседника не указывает... А так спасибо за такую разработку приложения и успехов вам в совершенствовании его ;)
We need this ASAP.

пожалуйста,поскорее делайте такие письма!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Its very useful feature request so I have made MediaRecorder working patch to record a video from webcam with getUserMedia. But I have couple of queries listed here below:

1. When chrome is planning to accept patches? .. blink M-32 ?

2. Is it plan for android nexus ?

3. Any specific reason for low priority for this activity ?

Please let me know what is your plan so that I can upload my patch.

It's been implemented in Firefox already
What Firefox Nightly implements is the new MediaStream Recording Proposal (MediaRecorder API) from

Also the implementation is for audio only.

Is this still way down on the priorities list? Would be an amazing feature to have, makes me sad to have to turn to dirty old Flash for this on my upcoming project.
