I need to play a video, how can I do it?

yes, you can do that with allegavi.

Anyone planning to add that for A5?

What are your reservations for bundling it with Allegro? What about having different bundles? AllegroLite could be the bare essentials and AllegroSuite could have a bunch of addons already together.

No real reservations or objections, it's essentially what I perceive to be the scope of such an addon that makes me think it should be a third party addon rather than an addon that is bundled with Allegro in the sense that it lives in Allegro's SVN tree (that's what "bundled with Allegro" means to me). If you did that the Allegro developers are in effect responsible for maintaining it on all supported platforms. I think that could be a huge undertaking and not one that I would volunteer for myself. That's my main reason for feeling it should probably be a third party addon, but that's purely a personal reason.
I should also stress that there is nothing wrong with having third party addons! In fact, they are encouraged.

There is also the slight concern of the extra dependencies it would bring in. They would be optional, of course, but still.

There's a matter of semantics as well.
To me, "bundled" means it's effectively part of Allegro and the burden of maintaining it is on the Allegro developers. If by "bundled" you mean someone takes Allegro plus whatever third party addons they think are useful and provides them in a single download, that's of course fine.

Now, my purely subjective comments on possible addons:

We have that already.

Wouldn't those depend very much on how you store things in your code?
Speaking for myself, I have a way to handle this that I like and prefer, but it's not so general that everyone can use it and I'm pretty sure not everyone would want to. I think that applies both ways.

This has been discussed in depth.

Mmmmmmyeah. Ok.

See above.

Again, that depends on how you represent your in-game data. Unless you want to force people to store their data in a certain way, I don't think this is easily done in a way that's general enough to be useful for everyone.

Again, these are my personal thoughts to those suggestions. Not saying it can't be done or no addon couldn't be made to do those, just saying I don't see some of these things being "low level" enough to easily provide a general implementation for.

And, again, there is nothing wrong with people providing third-party addons! In fact, do!.

Do you mean animated sprites made out of allegros bitmaps? Or where you thinking about a specific animated sprite format (like flic which I don't know much about)?

I too hava a solution for this which is using allegros bitmaps but it is in c++ and is only working when one is using the delta time method.
I was wondering about how one could write something like this not depending on those factors... maybe I can come up with something usefull. Or someone here has some good ideas.

will post some first ideas later.

EDIT:
Didn't want to go offtopic here. Made a new thread with the animated bitmap stuff here
