I am writing a video recording app but am finding it quite impossible to match the frames per second that are on the native Android device video camera app (on Samsung Galaxy sIII). On the native app I can record at 1920x1080 with effects on at an amazing FPS (not sure exactly what it is but it looks like 25+ fps).

In my app on the sIII my video recording is incredibly unstable and choppy even at 640x480. My FPS drops to 7 when recording at 640x480. When I add effects the FPS drops to 3-5.

Can someone help me figure out how to get an FPS that is equal to the native Android camera app (specifically on the sIII)?

At this point I'm not sure where to optimize.

Thanks!
