haxeVideo
haXe has a library called haxeVideo to play flash video streams. Here's a memo to install and play a demo video.
http://code.google.com/p/haxevideo/wiki/Help gives instructions, but its link to the download site is incorrect. http://haxevideo.org/ is the site for downloading haxevideo-1.1.zip. Install haxe's format library for compiling haxevideo:
$ haxelib install format
Unzip the file, and
$ cd haxevideo-1.1 $ haxe video.hxml
which creates video.swf and server.n. Run nekoVM server by
$ neko server.n localhost
will run RTMP server at port 1935 by default.
Run Apache2 and point to the directory the server is in, and then
http://localhost/video.html on a browser shows the page for video.

It worked ! Great

haXe
Found haXe at http://haxe.org interesting. Here's my first try to use it. Access to http://haxe.org/, hit "Download", then "Download linux installer". Untarring the file hxinst-linux.tgz creates an executable hxinst-linux. Open a terminal and do
sudo hxinst-linux
The monitor then looks like
![[[image: haxe.png]]](/frog/files/Teru/haxe.png)
Hit "はい"(y), installation starts, and finishes
![[[image: haxe1.png]]](/frog/files/Teru/haxe1.png)
Here's the log shown in the window:

Now, at http://haxe.org/doc, hit "Getting started with haXe/JS" and try the example there. Create Test.hx which has
class Test {
static function main() {
trace("Hello World !");
}
}Create compile.hxml in the same directory which has
-js test.js -main Test
Running
haxe compile.hxml
, creates test.js, which has

Test = function() { }
Test.__name__ = ["Test"];
Test.main = function() {
haxe.Log.trace("Hello World !",{ fileName : "Test.hx", lineNumber : 3, className : "Test", methodName : "main"});
}Create test.html as
<html> <head><title>haXe JS</title></head> <body> <div id="haxe:trace"></div> <script type="text/javascript" src="test.js"></script> </body> </html>
which shows on a browser like
![[[image: haxe2.png]]](/frog/files/Teru/haxe2.png)
which looks quite humbling in expression, but it works :-)
Now, how about flash?
Change the compile.hxml to
-swf test.swf -main Test
Recompiling by
haxe compile.hxml
creates test.swf. Change test.html to
<html>
<head><title>haXe Flash</title></head>
<body bgcolor="#dddddd">
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
width="400"
height="300"
id="haxe"
align="middle">
<param name="movie" value="test.swf"/>
<param name="allowScriptAccess" value="always" />
<param name="quality" value="high" />
<param name="scale" value="noscale" />
<param name="salign" value="lt" />
<param name="bgcolor" value="#ffffff"/>
<embed src="test.swf"
bgcolor="#ffffff"
width="400"
height="300"
name="haxe"
quality="high"

allowScriptAccess="always"
type="application/x-shockwave-flash"
pluginspage="http://www.macromedia.com/go/getflashplayer"
/>
</object>
</body>
</html>
and show on a browser
![[[image: haxe3.png]]](/frog/files/Teru/haxe3.png)
Modifying Test.hx to
class Test {
static function main() {
var mc : flash.MovieClip = flash.Lib.current;
mc.beginFill(0xFF0000);
mc.moveTo(50,50);
mc.lineTo(100,50);
mc.lineTo(100,100);
mc.lineTo(50,100);
mc.endFill();
}
}will draw a square on a screen. A program called swfmill is recommended to creaste a swf file. installed swfmill using Synaptic. As an example, create a file foo.xml like
<?xml version="1.0" encoding="utf-8" ?>
<movie width="640" height="480" framerate="12">
<background color="#ffffff"/>
<frame>
<library>
<clip id="foo" import="library/pic.png"/>
</library>
</frame>
</movie>and ran
swfmill simple foo.xml bar.swf
Change Test.hx to
class Test {
static function main() {
var but = flash.Lib.current.attachMovie("foo", "pic001", 0);
but._x = 10;
but._y = 20;
}
}
and compile.hxml to
-swf test.swf -swf-lib bar.swf -main Test
Ran
haxe compile.hxml
and test.html on a browser looks like
![[[image: haxe4.png]]](/frog/files/Teru/haxe4.png)
where the parameters for size were changed to cover the picture size.
