This API is available on Firefox OS for privileged or certified applications only.
Summary
The onRecorderStateChange
property is used to set an event handler to listen to the recorder state change. This can happen either because the recording process encountered an error, or because one of the recording limits set with CameraControl.startRecording()
was reached.
Syntax
instanceOfCameraControl.onRecorderStateChange = funcRef;
Where funcRef
is a function to be called when the recorder changes states.
This function takes one parameter, which is one of the following strings:
FileSizeLimitReached
VideoLengthLimitReached
MediaRecorderFailed
MediaServerFailed
TrackCompleted
TrackFailed
Example
// back or front camera var whichCamera = navigator.mozCameras.getListOfCameras()[0]; var options = { mode: 'picture', recorderProfile: 'jpg', previewSize: { width: 352, height: 288 } }; function onSuccess( camera ) { var outputString = { FileSizeLimitReached : "The file size has reached its limit", VideoLengthLimitReached: "The time limit for the video has been reached", MediaRecorderFailed : "The recorder encountered an error", MediaServerFailed : "The media source encountered an error", TrackCompleted : "The recording ended nicely", TrackFailed : "Something went wrong" }; camera.onRecorderStateChange = function (value) { console.log(outputString[value]); } }; navigator.mozCameras.getCamera(whichCamera, options, onSuccess)
Specification
Not part of any specification; however, this API should be removed when the WebRTC Capture and Stream API has been implemented.
