I want to show filtered camera preview while recording a video using media recorder. To filter the preview i need frames normally which i can get that from onPreviewFrame() function but while recording video with media recorder, onPreviewFrame() function does not get called. So what i want to know , is there any other ways to get these frames for filtering and then show them after modification ? I checked some apps from Google Play for example, Videocam Illusion. Its showing preview with effects during recording videos. I want to do something like that but have no hint how to do so. So i will appreciate any help/hints/code/sample regarding the issue. Thanks.
