windows media encoder scripting |
|
|
I planning a live webcast using windows media.
I wan't to make a player embedded on a webpage (no problem) and have the
webpage show text as the webcast moves on.
I don't know in advance when text shoud be shown, I just know what text
to show. I therefor have to add a marker or something like that, when
encoding and capture the marker on the web embedded player. This should
be no problem either, but how do I add markers to the file?
I know of the script panel, and have played a little with it. If I use
the script panel, is there any way of saving the scripts when I archive
the file for later use?
I would like to reuse the script commands/markers for on demand
broadcasting.

The "something" is called a script command

You add them in the script panel (you have to define a profile which
uses script events, by selecting the script panel checkbox)

The script commands are embedded in the outgoing stream and the saved
file.

The player fires an onScriptCommand event when a command is received.
You can trap that and show the value of the script event in a (div /
textbox / whatever) as desired.
This is the code I usually use :
<script language="javascript1.2" type="text/javascript">
function ss_addEvent(elm, evType, fn, useCapture) {
// By Scott Andrew
try {
if (elm.addEventListener) {
elm.addEventListener(evType, fn, useCapture);
return true;
}
}
catch (err) {
try {
if (elm.attachEvent) {
var r = elm.attachEvent("on"+evType,
fn);
return r;
}
}
catch (err) {
return false;
}
}
}
function pageLoaded() {
player=document.getElementById("mediaplayer");
player.attachEvent("scriptcommand",handleScriptCommand);
}
function handleScriptCommand(commandType, commandText) {
switch (commandType) {
case "text" :
alert("sent script command "+commandText);
}
}
</script>

Shouldn't I be able to see the script commands if I opened the file in
windows media file editor?
I have tried enabeling archiving om the server, and saved the file in
the encoder. Neither of the two files have script commands embedded.

You should, as small markers on the timeline.
How are you generating the script commands ?
I mean, what buttons etc do you press ?

I have tried following the guide at
http://www.microsoft.com/windows/windowsmedia/howto/articles/adswm.aspx#inserting_event_script_commands_in_the_broadcast_stream__xdbw
I can insert text, url's and script commands fine.
I sype in the text in the script panel, and push insert.
The total scripts counter in the monitor panel counts one up, when I
insert a script.
If i look at the stream in wmp, and insert text commands, it shows up,
so I know it is inserted, but I'm still unable to see the commands in
file editor. If i click the "Script commans..." button the list is empty.

It's because they're in a "script stream" and need to be in the wmv
file header instead. It's easily fixed, though :
