Stream objects

Hi!

I was wondering if Iliad has/will have some object to manage streaming
files like .ogg and .ogv (or mp3, wmv, for that matter). I am told
that probably html5 makes this 100% obsolete, but I admit my full
ignorance in the matter of HTML5... do we need this stuff at all or
can I simply wait for the next Firefox upgrade?

Hi Berto,

I'm forwarding this to Janko who is the current Swazoo maintainer. I
know he successfully streams flv files with Swazoo.

About the video tag in HTML5, IMHO as long as all modern browsers don't
support it, you have to at least be able to degrade to a flash player.

Cheers,

Nico

Hi guys,

Yes, Swazoo has streaming impelemented, in both input (uplaod) and
output (download) directions. It works nicely, I serve all my static
content through Swazoo on my hosting now :)

More on http://www.swazoo.org/streaming.html

How you stream big files you can see in Aida, look at FileProxy class,
then AIDASite>answer:toGetOrPost:on:

Best regards
Janko

So, this appears to be technically possible, but it requires some
tweaking Iliad-side to import Aida's streaming, if I get Janko right.
The next question is whether this is already planned or not.

I use Apache as a front end server, and it serves all static files.
If you really want to use a 100% smalltalk solution, I guess Swazoo is
your best shot, but I would rather use a more robust solution for that.

Hi all,

the following classes do the job fine for me, since I'm developing a
local application that needs only being served to Firefox. I suppose
we can work on them to add javascript degradation for IE and the like,
if Nicolas confirms that what I did is Iliad-like. It's my first time
as an HTML tag creator, so I'm not 100% sure this is what the classes
are supposed to look like.

Hi Bèrto,

This is nice :)

From what I saw it's exactly how it's supposed to look like.
Did you follow HTML5 specs?

The only problem is that the video tag is a HTML5 tag, and you are
building it inside an XHTML1.0 page...

I guess I should rename some classes and add methods to be able to
change the doctype ;)

Then we could add some other elements for HTML5, like date inputs, etc
and put them is an HTML5 category.

What do you think?

Cheers,
Nico

Nice for me :) I admit having made almost NO study about HTML 5, I
simply went to the w3c page and implemented the stuff just as they
described it, it actually worked out-of-the-box in FF 3.5 with .ogg
audio and .ogv video (provided that apache knows about the mime types
it's streaming). In the far future I'll probably want to use swazoo,
so people do not need installing apache for a local app, but this is
FAR in the future.

I'll be busy finishing the demo for a couple of weeks, but I'm willing
to take up the issue right after that (we need to request funds, so
it's nice if I have some basic magick to show ;). I'd agree that the
best thing to do is to follow w3c specs, especially since they're very
clear and require almost no effort to be implemented.
