FFMPEG

Hi,

first I would like to congratulate the developers for all the
improvements done in version 2.0.

I was doing some tests on Windows and updating the software to 2.0, when
I realized that ffmpeg is now used on Windows by default. It has one
important consequence for me, is that the function cvSetCaptureProperty
that can reach a given frame (with parameter CV_CAP_PROP_POS_FRAMES) is
not well implemented, if at all, in ffmpeg. Therefore, one cannot go
directly to a frame of a given number, while it used to be possible with
the previous implementation (using VfW or DirectShow?).

Is there a way around this? Is there a way to compile OpenCV2.0 with the
previous video library?

Thanks!

Nicolas

Hi Nicolas,

I've got exactly the same issue with my software. Have you already found a solution?
Would be great to get some information.

Cheers
Markus
