Right, demuxer was kept for animated gifs, since decoder cannot handle
them yet. It should be removed though.

I guess your patch applies to decoder as well, feel free to commit.

Hummm, not sure, with image2 mechanism only one packet containing the
whole gif will be given to the decoder which will output more than one
frame. I remember Michael wanting a parser for this case last time I asked.
