I want to find out if the VideoTrack contains a screenshare or webcam stream. I can't find any attribute and also no fitting contraint I could apply to the track and read out later.
Someone knows a smart way to do that?
I want to avoid sending the streamId with the type over the dataChannel.
Thanks :)
EDIT1: So far no solution... so I have to send the streamType and StreamId over the datachannel
The process works like this (using MediaStreamTrack as an example):
If needed, call MediaDevices.getSupportedConstraints() to get the
list of supported constraints, which tells you what constrainable
properties the browser knows about. This isn't always necessary,
since any that aren't known will simply be ignored when you specify
them—but if you have any that you can't get by without, you can
start by checking to be sure they're on the list.
Once the script knows whether the property or properties it wishes
to use are supported, it can then check the capabilities of the API
and its implementation by examining the object returned by the
track's getCapabilities() method; this object lists each supported
constraint and the values or range of values which are supported.
nally, the track's applyConstraints() method is called to configure
the API as desired by specifying the values or ranges of values it
wishes to use for any of the constrainable properties about which it
has a preference.
The track's getConstraints() method returns the set of constraints
passed into the most recent call to applyConstraints(). This may not
represent the actual current state of the track, due to properties
whose requested values had to be adjusted and because platform
default values aren't represented. For a complete representation of
the track's current configuration, use getSettings().
In the Media Stream API, both MediaStream and MediaStreamTrack have constrainable properties.
