Is there any way to download videos from http://chat.pixiv.net?
I managed to rip the swf, but it's only for the player, not the video itself

Looks like it's a custom format. It's not actually a video, it's a log of what the artist did (properties of each stroke and where it went) that the flash plays back. You'd have to render and record it somehow if you wanted a video file.
Here's what one of them looks like (hexdump):

(That's only a small excerpt.)
You could probably get a start on reverse-engineering the format by decompiling the swf player and looking at the actionscript, but you'd still have quite a bit of work ahead of you to actually render to a video. Could be an interesting project, but I don't really care enough or have the time. Maybe someone else will.
