We tried to use XwalkView() to load a JS with getting the camera via
getUsermedia API.
The camera can be called.
You could reference Our JS codeļ¼
try {
navigator.getUserMedia = navigator.getUserMedia ||
navigator.webkitGetUserMedia;
navigator.getUserMedia({video: true}, function(s){
var url = webkitURL.createObjectURL(s);
$("#localView")[0].src = url;
$("#localView").show();
$("#errormassage").hide();
}, function(error){
$("#errormassage").show();
$("#errormassage").html("Get user media occur error:<font
color='red'>PERMISSION DENIED</font>");
});
} catch (e) {
$("#localView").hide();
$("#errormassage").html("Get usr media occur error,with error
message:<font color='red'>"+e.message+"</font>");
}
Thanks

Subject: [Crosswalk-help] Unable to access the environment camera after Android
has called camera.unlock()
Before launching an embedded xWalk view (crosswalk-webview-10.38.225.0-arm),
I'm grabbing a camera reference for the rear(environment) camera in order to
turn the LED on in torch mode.
In the Android activity:
...
rearCamera = Camera.open();
rearCamParams = rearCamera.getParameters();
rearCamParams.setFlashMode(Parameters.FLASH_MODE_TORCH);
rearCamera.setParameters(rearCamParams);
rearCamera.startPreview();
rearCamera.unlock();
and the JS in the HTMLl that is being loaded by the XWalkView:
...
if(sourceInfo.kind == "video" && sourceInfo.facing == "environment") {
videoSourceId = sourceInfo.id;
...
navigator.getUserMedia({audio: true, video: {optional: [{sourceId:
videoSourceId}]}}, function(stream){
$('#my-video').prop('src',
URL.createObjectURL(stream));
The following errors are emitted by chromium:
10-30 10:35:21.008: E/VideoCapture(23490): allocate: Camera.open:
java.lang.RuntimeException: Fail to connect to camera service
10-30 10:35:21.008: E/chromium(23490):
[ERROR:video_capture_device_android.cc(193)]
VideoCaptureDeviceAndroid::SetErrorState: failed to allocate
Ideally, I'd like to be able to turn on the rear camera LED light by adding a
property to the video object in JS or using unlock method to allow Crosswalk to
access the camera.
Is there another way to accomplish this? Any assistance would be greatly
appreciated,
Kevin
