#2I wish there was some way to get vlc to use external sprite files.
While I'm thinking about it, external chapter files would be great too. Then you could make your own bookmarks without modifying the video file.

#3Back in the day a sprite was a smaller 2d bitmap you'd superimpose on the screen. A key frame was a marker like this.

I’m trying to remember the name of a UI control that could be backed by something like this. It was a sequence of thumbnails laid out in a row like a film strip. (For all I know, that was what it was called.)

Yes, and the sprites were supported by a specific coprocessor. For example, the Apple II didn't have one.

Could be a poster frame or chapter frame or chapter marker

#8A long time ago, we used this approach to play videos at 15 fps in IE6, with no flash or realplayer plugins required! No sound though...

#9Is it common to call these sprites in British English? I would call them "thumbnails".

The term "sprite" is mostly used in games. A single image file that contains multiple sub-images is called a "sprite sheet". (This reduces overhead compared to loading a large number of image files.) In this case they happen to be video thumbnails.
