[vlc-devel] grabbing frames with vlc 1.1.0

[Mehmet Kaplan]

AFAIK, gst-launch is a UNIX command. I develop my program on windows.
Also Mplayer captures all frames correctly, too.
My problem is I want to grab a frame interval (for example frames
between 3-15 seconds).
But Mplayer seeks only to keyframes and capture frames from an
interval different from which I want.
But VLC seeks exactly to the desired position, but VLC produces less frames.
So, I want to use VLC, but captured frames are incomplete.

P.S. Capturing all frames with Mplayer and taking only a frame
interval is possible, but it is time consuming and inappropriate.
