---------------------------------
Fix Version/s: (was: 2.4.0)
> use of camera in cordova video mode results in field of view different than
> in native video mode
> ------------------------------------------------------------------------------------------------

> Key: CB-1499
> URL: https://issues.apache.org/jira/browse/CB-1499
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Environment: iOS 5.1.1, iPhone 4
> Reporter: R Li
> Assignee: Shazron Abdullah
> Priority: Minor
> Labels: newbie
>
> The video recording function requires different camera distance from object
> compared to native iOS camera
> Using:
> <pre><code>
> // capture callback
> var captureSuccess = function(mediaFiles) {
> var i, path, len;
> for (i = 0, len = mediaFiles.length; i < len; i += 1) {
> var data = [
> {type: mediaFiles[i].type, src: mediaFiles[i].fullPath}
> ];
> var map = {type:"type", src:"src"};
> app.populateWidget("HTML5Video", data, map);
> app.setData("label", mediaFiles[i].type + "::" +
> mediaFiles[i].fullPath);
> break;
> }
> };
> // capture error callback
> var captureError = function(error) {
> navigator.notification.alert('Error code: ' + error.code, null,
> 'Capture Error');
> };
> // start audio capture
> navigator.device.capture.captureVideo(captureSuccess, captureError);
> </code></pre>
> records video fine on my iPhone 4 (iOS 5.1.1), except that the camera must be
> placed closer to the subject than when using the native video function of the
> iPhone. For example, when shooting a video of an object (e.g., my computer
> screen) that encompasses the entire viewfinder screen of the iPhone 4 in the
> native iPhone feature, the camera was placed about 10 inches away from the
> object. Using the PhoneGap:build and above code resulted in having to move
> the camera closer to the object (i.e., ~ 5.5-6.0 inches away) in order to
> have the object encompass the entire viewfinder screen.
> Is there a way to get the camera in the PG build to act exactly like the
> native function so the camera is exactly the same distance from the object?
> For clarification perhaps, think of the issue in the following manner:
> (1) using the NATIVE video mode of the camera, measure the distance the
> camera/phone is away from an object (e.g., your computer screen), as measured
> when the computer screen occupies the entire width of the phone camera
> screen.
> (2) use the Phonegap/Cordova code video mode and measure the distance the
> camera/phone is away from the same object (e.g., your computer screen) when
> the computer screen occupies the entire width of the phone camera screen.
> You should see a significant difference in the distance the camera/phone has
> to be from the object when using the 2 different iOS camera functions (i.e.,
> native vs Cordova).
> **NOTE: It appears that the Cordova video camera function is using the iOS
> native (still picture) camera settings when trying to record a video, as
> opposed to using the iOS native VIDEO camera settings. I am deducing this to
> be the case since, when running the same distance test as outlined above I
> can see the same effect of different distances away from the object when
> testing the native iOS camera vs native iOS video toggle. That is, the native
> iOS camera has to be closer to the object to fill up the entire camera screen
> versus when using the native iOS video mode.
> Thanks.
