OS X Mavericks broken OpenCV VideoCapture frame numbers ?
20 novembre 2013, par MattPFresh install of Mavericks, managed to install ffmpeg via homebrew and compile the latest OpenCV at time of writing. My code is written in Python (though this shouldn't affect this issue) and basically navigates a video file using the
VideoCapture
class with the properties set frame position and get current position.The issue is, on prior versions of OS X, various Linux and Windows boxes, this works without issue. Each frame number is of the format i.0, where i is the current frame number (why it is a float anyway is confusing, alas it's how OpenCV gives it back). However, on this setup I get frame progressions like :
0.0 -> 1.3972597329753 -> 2.999999999 -> 3.9999999 -> 5.0 -> 6.252323552
This makes using the properties for getting / setting the current frame position impossible and, as one would imagine, causes the automated playback thereof to fail. I can only assume ffmpeg is reporting things odd such that OpenCV is incorrectly calculating frames, but have been unable to rectify this.
Has anyone any insight into the problem, and/or possible solution ? Thanks.
