Hi, I'm using FFMpegFrameGrabber to a mp4 file , I use getLengthInvideoFrame after start method, and I get 2108 frames, But when I grab every video frames, totally only 2107 frames, the getLengthInvideoFrame returned is not the real frame count, How can I get the accurately frame count beore grab one by one? Thank you
