videoFrameRate property
The target video frame rate in frames per second.
This is the target recorded video output frame rate per second if the application configures the video recording via MediaRecorder.setProfile without specifying any other MediaRecorder encoding parameters. For example, for high speed quality profiles (from qualityHighSpeedLow to qualityHighSpeed2160p), this is the frame rate where the video is recorded and played back with. If the application intends to create slow motion use case with the high speed quality profiles, it must set a different video frame rate that is corresponding to the desired output (playback) frame rate via MediaRecorder.setVideoFrameRate. For example, if qualityHighSpeed720p advertises 240fps videoFrameRate in the CamcorderProfile, and the application intends to create 1/8 factor slow motion recording videos, the application must set 30fps via MediaRecorder.setVideoFrameRate. Failing to do so will result in high speed videos with normal speed playback frame rate (240fps for above example).
In Android native code: If the application intends to do the video recording with MediaCodec encoder, it must set each individual field of MediaFormat similarly according to this CamcorderProfile.
