hi I am working on a real-time video processing project. I used setPreviewCallbackWithBuffer() and display both the preview image and the processed image on SurfaceViews. Now, I'd like to record video at the same time. I read from some posts that the video recording involves low-level io that is not in conflict with the preview buffer.
I took some sample code from the second post of this link to do the video recording: http://stackoverflow.com/questions/1817742/android-video-recording-sample however, after merging it with my camera setPreviewCallbackWithBuffer() code, I kept getting "MediaRecorder: start called in an invalid state 4" when I tried to call mrec.start(). Both the initRecorder() and prepareRecorder() ran fine when the surface is created. Anyone know what might be causing this error? the MediaRecorder object does share the same camera object that is used for buffered preview. thanks Qianqian -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
