This feature gives developers the ability to access Near Field Communication (NFC) functionality of a device, such as reading and writing NFC tags as well as exchanging data between NFC capable devices.

Editor's draft

This API allow you to access USB devices from the browser.

It is a W3C editor's draft: https://wicg.github.io/webusb.

A user is prompted for permissions to access the microphone *each* *time* they access a page that calls getUserMedia().

This is makes web apps that are used regularly essentially unusable, because the user permissions dialog pops up at every page load.

Both FF and Chrome support persistent user permissions.

As arithmetic coding patents for JPEG have now expired, it would be nice to support arithmetic coding in the JPEG. It will allow recompress existing JPEG files using arithmetic coding losslessly, as the result size of all JPEG files will be reduced by 10%.

Please develop a Webex extension so that Webex webcasts can be accessed through Microsoft Edge. I really like Edge, but I watch quite a few Webex webcasts, which I have to view through Chrome. A nuisance.

AMR is widely used on mobile devices when recording voices. It's useful to play amr directly on web.

Spec: https://www.w3.org/TR/mediacapture-depth/

This specification extends the Media Capture and Streams specification [GETUSERMEDIA] to allow a depth-only stream or combined depth+video stream to be requested from the web platform using APIs familiar to web authors.

Please add support for embedded audio in SVG animations in EDGE.
For example to playback files like this:

https://imgh.us/LoveDota.svg

On Chrome and Safari it works fine. Not on EDGE.

Many cartoon episodes on the web require SVG embedded audio.

Please add support for Media Source Extensions to Internet Explorer 11 on Windows 7. This update will match what is currently available using Chrome or Firefox.

In addition it is very confusing that this feature is available on IE 11 with Windows 8 and 10 but not 7.

Spec: https://w3c.github.io/mediacapture-fromelement/index.html#html-canvas-element-media-capture-extensions

Defines a canvas.captureStream() method allowing real-time capture of a <canvas> element into a MediaStream.

Use cases include local transcoding using the MediaRecorder API, game streaming, lots more.

Hi,

H265 aka HEVC is the successor of the H264 video format.
HEVC is said to double the data compression ratio compared to H.264/MPEG-4 AVC at the same level of video quality. It can alternatively be used to provide substantially improved video quality at the same bit rate. It can support 8K UHD and resolutions up to 8192×4320.

What about to support this in Microsoft Edge and IE?

WAA AudioContext has a supend and resume call per the official spec. This will stop/resume audio playback and also stop.resume the audio clock. Without this, any playing buffers or buffers queued for playing will need to be stopped, and restarted from where they left off, which can get messy.

When I try to call print() multiple time in succession, the print dialog shows: Nothing was sent to print. Open a document and try again.

Chrome and FF prompt user with multiple consecutive print dialogs instead.

All major browsers support data uri for images, audio and video. IE only supports it for images.

it is the predecessor of vp9. but still used by youtube.

Edge does not play bgsounds (background sounds) like music on web pages. Internet Explorer played .wav sounds perfectly, but since upgrading to Windows 10 and Edge, all the sounds on web pages are no longer working. I checked and Adode Flash is active but still no sounds.

In IE, there was print templates to manage printing pages. Like MeadCo ScriptX ActiveX plugin, we need to be able to do everthing programmatically that can be achieved with print dialog and print templates. It would be great if it becomes HTML5 specification too.(Raw Printing should also be included).

Standardizes a URL fragment syntax for specifying a fragment of a media resource.
