I set the preview frame rate to the lowest rate possible with this code, but you could set it to the highest rate possible by using l_last
instead of l_first
in the List index (mCamera
is a member variable that references the Camera and is set elsewhere in the code).
Camera.Parameters l_params = mCamera.getParameters();
List<int[]> frameRates = l_params.getSupportedPreviewFpsRange();
int l_first = 0;
int l_last = frameRates.size() - 1;
int minFps = (frameRates.get(l_first))[Camera.Parameters.PREVIEW_FPS_MIN_INDEX];
int maxFps = (frameRates.get(l_first))[Camera.Parameters.PREVIEW_FPS_MAX_INDEX];
l_params.setPreviewFpsRange(minFps, maxFps);
mCamera.setParameters(l_params);

You can use public List<int[]> getSupportedPreviewFpsRange ()
to check what FPS range supported by your device. Here is mine:
preview-fps-range-values=(10000,10000),(15000,15000),(15000,30000),(30000,30000);
so if I want to change the fps to 15, I can setPreviewFpsRange(15000,15000)
.
