streaming video problem

I want to make a screen, and when the user clicks on it, a video should start.

I've created a simple screen with a unique texture on it.

When I enter the texture and media link under the 'media'-tab in About Land I can play the movie using the little player buttons on the bottom of the screen. This works, I get image and sound.

When I however want to activate the movie through a simple script, nothing happens... The texture which needs to be replaced stays in place... no image nor sound will play...

I'm no script guru... so maybe something is wrong here
the script used:

-----------------------------------------------------------------------------------
string Texture = "playscreen";
string Url = "http://www.merge.nl/huijs/Sample.mov";

default
{
state_entry()
{
llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_STOP] );
llSleep(1);
llSay(0, "stopped";
llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_UNLOAD] );
llSleep(1);
llSay(0, "unloaded";
llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_TEXTURE,Texture] );
llSleep(1);
llSay(0, "loaded" + Texture);
llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_URL,Url] );
llSay(0, "loaded" + Url);
}

touch_start(integer total_number)
{
llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_PLAY] );
llSay(0, "Sarted playing";
}
}
--------------------------------------------------------------------------------------------

key Texture;
string Url = "http://www.merge.nl/huijs/Sample.mov";

default{
    state_entry(){
        Texture = llGetInventoryKey("playscreen");
        llParcelMediaCommandList(
          [PARCEL_MEDIA_COMMAND_STOP,
          PARCEL_MEDIA_COMMAND_UNLOAD,
          PARCEL_MEDIA_COMMAND_TEXTURE,Texture,
          PARCEL_MEDIA_COMMAND_URL,Url]
        );
    }

    touch_start(integer total_number){
        llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_PLAY] );
        llSay(0, "Sarted playing");
    }
}

Should do the trick.
The texture should be a key and not a name.
Also, wrapping as many commands into the media command list cuts down execution time, because each call delays the script for 2 seconds.

You will need mod/copy/trans rights on the texture for this to work. llGetInventoryKey will fail if you do not have full perms.

Edit: corrected Texture assignment outside of state.

thank you! A lot of helpfull tips

one thing...

I placed the script and checked the texture for the mod/copy/trans rights, they are all checked. I placed the texture in the prim's contents, but the line:

key Texture = llGetInventoryKey("playscreen";

Produces a syntax error...

Sorry, was doing it on the fly without being in world to check.
The problem is assigning the key outside of a state, only simple values can be assigned there.

Try this one:

 key Texture;
string Url = "http://www.merge.nl/huijs/Sample.mov";

default{
    state_entry(){
        Texture=llGetInventoryKey("playscreen");
        llParcelMediaCommandList(
          [PARCEL_MEDIA_COMMAND_STOP,
          PARCEL_MEDIA_COMMAND_UNLOAD,
          PARCEL_MEDIA_COMMAND_TEXTURE,Texture,
          PARCEL_MEDIA_COMMAND_URL,Url]
        );
    }

    touch_start(integer total_number){
        llParcelMediaCommandList( [PARCEL_MEDIA_COMMAND_PLAY] );
        llSay(0, "Sarted playing");
    }
} 

thanks sys!
