I am trying to capture video form an USB camera into a video file. I
have noticed two strange things, however:
- the frame rate (CV_CAP_PROP_FPS) of the input video source is always
- the whole capturing procedure always yields an empty file,
regardless of what codec and frame rate I set.
I have already tried cvQueryFrame before getting the fps property but
it remains zero all the same.
And I think the codecs I tried (MJPEG and FLV1) are installed: MJPEG
is included in Windows XP SP2 [http://support.microsoft.com/kb/899113]
and I have an FLV player installed.
I saw others already had these issues in this group but there was no
real workaround yet...
