Android - Is it possible to 'lock' the preview frame rate of a camera?

Question

I am trying to create a video recording app that records videos in 24 FPS. I am using the following code in an attempt to lock the FPS to 24:

Camera.Parameters params = mCamera.getParameters();
params.setPreviewFrameRate(24);
params.setPreviewFpsRange(24000, 24000);

And also the following CamcorderProfile that is used with MediaRecorder:

CamcorderProfile ccp = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
ccp.videoFrameRate = 24;

Unfortunately, it only works when the video is taken in low light situation, but once I go outside when there's light, the video starts recording in 30 FPS.

Is it possible to lock the frame rate to 24fps also in broad daylight?

Thanks in advance!

Answer 1

public List<Integer> getSupportedPreviewFrameRates ()

check this list. I suppose that you just cant set frame rate that is not listed there. It may be because of codecs modification that are used in Android OS.
