The Android camera API doesn't allow this. A new capture can be made only after the JPEG image is available. Google added a whole new camera API in Android 5.0 which supports burst mode. Qt doesn't support it yet, we'd need a new backend for that. What you could do is use QVideoProbe to retrieve a viewfinder frame just before calling capture(). Note that its format will be NV21 and you'll have to do the conversion yourself. -- Yoann _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
