Hi,

I've got a problem scripting the mozilla plugin with Javascript.
I try to start my TV card using javascript with this code:

Code: Select all

function startKan() {
	document.video1.add_item('dshow:// :dshow-vdev="Hauppauge WinTV PVR PCI II Capture"');
	document.video1.play();

}

but this doesn't work, it starts the first directshow device that is my webcam, so it does the same thing as if I would use:

Code: Select all

function startKan() {
	document.video1.add_item('dshow:// ');
	document.video1.play();

}

I thought it was a problem with escape charecters or something , but it doesn't seem to be. (tried a lot of things)
I also saw a post about using an "options" array because the vlc plug-in wouldn't parse the string or something (in IE by the way). But that also gives the same result.

Could somebody give me a working example code to start the TV card?
many thanks

BTW. I use 0.8.4a for windows 32 on WinXP of VLC

I did some more testing, and I now have some code that works in internet explorer with the ActiveX plug-in:

Code: Select all

<html>
<head>
</head>

<input type=button id="start" value=" Play " onClick='StartTV()'>

<object classid="clsid:E23FE9C6-778E-49D4-B537-38FCDE4887D8" codebase="http://downloads.videolan.org/pub/videolan/vlc/latest/win32/axvlc.cab"
        width="400" height="300" id="vlc" events="True">
<param name="Src" value="" />
<param name="ShowDisplay" value="True" />
<param name="Loop" value="False" />
<param name="AutoPlay" value="False" />
</object>

<script>

function StartTV()
{
	var options = new Array(":dshow-vdev=Hauppauge WinTV PVR PCI II Capture");
	document.vlc.addTarget("dshow://", options, 4+8, -666);
};

</script>
</body>
</html>

The problem is that the ActiveX plug in isn't mentioned in the documentation on the website. Does anybody have a link to a little bit of documentation?
I would really like to know why I need to add the ", 4+8, -666" in the addTarget tag. I doesn't work without is, But I don't have a clue about what it does.

But back to my Problem: this doesn't work in firefox!
The equivalent in the code for the mozilla plug-in:

Code: Select all

<html>
<head>
</head>

<input type=button id="start" value=" Play " onClick='StartTV()'>

<embed type="application/x-vlc-plugin"
         name="vlc" autoplay="no" loop="no" width="400" height="300"
         />


</object>

<script>
<!--

function StartTV()
{
	var options = new Array(":dshow-vdev=Hauppauge WinTV PVR PCI II Capture");
	document.vlc.add_item("dshow://", options, 4+8, -666);
	document.vlc.play();
};

//-->
</script>
</body>
</html>

But this does not work! the "add_item" method doesn't do anything with the added options array, so it just starts the first directshow device (a webcam in on my configuration)

does anybody have a solution?

Another question I have about the ActiveX plug-in functions.

Can the video screen be resized using javascript?
If the videoscreen has an ID named "vlc"
You could change the attributes like this:

document.vlc.height = "480";
document.vlc.width = "640";

But this doesn't resize the screen when using the ActiveX plug-in. Are there other resize functions in this plug-in?

The above code does work perfectly with the Mozilla plug-in.

Also in both the Mozilla plug-in and the ActiveX plugin
document.vlc.fullscreen();
Works perfectly to fill the screen in both implementations.

I also noticed that the Mozilla plug-in can crash firefox of you open the plug-in multiple times. Is this a known bug?

for resize use:
document.vlc.style.height="100"

use it as
add_item('string');
then it works well
