I'm currently developing application using the camera for iphone in HTML5 with

<input type="file" accept="capture=camera">

The problem is that I have a little list that give me the choose between my library and my camera.

My idea is to have two buttons, one for the library and an other for the camera.

I know the way to only give the library but not for the camera.

Question: Is there a way to separate the two types?

Unfortunaly not possible :/

Extract from HTML Media Capture - Security and privacy considerations :

In addition, the User Agent implementation is advised to provide an indication to the user when an input device is enabled and make it possible for the user to terminate such capture. Similarly, the User Agent is advised to offer user control, such as to allow the user to:

• select the exact media capture device to be used if there exist
  multiple devices of the same type (e.g. a front-facing camera in
  addition to a primary camera).

• disable sound capture when in the
  video capture mode.
