How to extract all frames from movie?

How to extract all frames (as PNG but preferable as BMP, in RAM) from movie without showing the video lan player window?
I am using Delphi (PasLibVLC).

I see an example using libvlc_media_player_next_frame and libvlc_video_take_snapshot. But it uses the video player window.

Some pseudo code will be great IF possible. If not, I need at least the basics (accessing video WITHOUT showing the player window).

You can dump frames with the video output callbacks but note that VLC is not frame-accurate.

Thanks Remi. What "not frame-accurate" means? Will it drop/skip frames?
