I'm reposting this on the devel list, hope some-one can point me in the
right direction.

I'm confused about when to use a parser and when to use a demuxer. I have
been trying to study the img2 code, and i'm surprised that a simple image
format like pnm has a parser, yet a complex one like gif does not. does
anyone have any opinions on this, because it seems there is no clear line
when to use one or the other, and the definitions of a parser i have found
are much to general to be of use. I want an ffmpeg world view of this.

mark
