Error in IE

P: n/a
Hi I am creating a page for stretchfilm. In this page you can chose
between a short medium and long version of the film at any point in the
film.

It is in norwegian, but just press play.

URL:

http://www.media.uio.no/sherlockholm...&hastighet=lav
In IE I can see up to clip 14, but then I get a fatal error and IE
shuts down. I can not figure out what's wrong, but I assume it is an
inddinte loop or something.

I use the XML for SCRIPT to read the xml-document with info of the
film.

the XML looks like this

«?xml version="1.0" encoding="UTF-8" standalone="yes" ?»
«sherlock»
«meta streamUrl="rtsp://lillestroem.uio.no:554/div/imk/strekktekst/"
refUrlLav="320/" refUrlHoy="800/" soundUrl="./" /»
«M1»
«movie level="1" refFile="L1M1" need="none" length="none"
addSoundSrc="none" /»
«movie level="2" refFile="L2M1" need="none" length="none"
addSoundSrc="none" /»
«/M1»
«M2»
«movie level="1" refFile="L1M2" need="none" length="none"
addSoundSrc="none" /»
«movie level="2" refFile="L2M2" need="none" length="none"
addSoundSrc="none" /»
«/M2»
«M3»
«movie level="1" refFile="L1M3" need="none" length="none"
addSoundSrc="none" /»
«movie level="2" refFile="L2M3" need="none" length="none"
addSoundSrc="none" /»
«movie level="3" refFile="L3M3" need="none" length="none"
addSoundSrc="none" /»
«/M3»

etc...

Your page worked on the most recent Firefox browser. I use a modified
IE6 browser know as the SBC/Yahoo DSL browser. On it the movie will not
show at all. Rather you get the following error message when you try to
play the movie:

An error has occured in the script in this page
Line 221
Char 3
Error 'null' is null or not an object
Code 0
URL http://www.media.uio.no/sherlockholmes/main.php?

I do not have time to investigate your very long code, but hopefully
this error information will help you locate the problem.

After the error message appears, the computer locks and fails to
respond to anything. I finally escaped by pressing Ctrl,Alt, and Delete
together several times, selecting to delete the program several times,
and then selecting to stop a non-responding program. That finally shut
down the browser and allowed the computer to be used again.

Thank you

I got the same error with opera. It seems that opera and your browser
have problems with XML for SCRIPT. The variable "domDoc" is considered
empty by opera, although it should contain the xml. See the
generalfunctions.js - loadLocalURL, callbackfunction and loadNextMovie.
This do not explain why IE can run for several minutes and then crash.

An interesting numeric correlation with
<http://groups.google.com/group/comp.lang.javascript/browse_frm/thread/bfe29ce5f0f60579/e433d8c23241ac59?hl=en#e433d8c23241ac59>
It may be a pure occasion or maybe IE indeed has some "hurt tolerance"
set to max 13 ? :-)

Overall you cannot crash IE so easy. A rude application shutdown
usually indicates that your browser gave up control to some COM control
and now it cannot neither take control back nor dismiss the control
(Windows' blue screen state equivalent). In your case such controls are
MSXML and QuickTime. You may check:

1) To make things easier :-) local files have readyState of success
equal to 0 and not 4. So for debugging period you should always have:
if ((myRequest.readyState == 4)||(myRequest.readyState == 0)) {
// success
}

2) To make things even more easier :-) XMLRequest doesn't honor file
extentions (say .xml) but HTTP content header only. As you cannot set
this header for local files, you really cannot use XMLRequest properly
while on your local drive. The only option is to load XML data as plain
text and parse it after. I see you already do it but check the whole
routine once again.

3) JavaScript is barely usable for pinpoint synchronized media streams.
There are too many issues that uncontollably add / extract milliseconds
and whole seconds from your calculations. With IE you have much more
power and control by using Time behaviors:

Hoping it helps anyhow...

This time approach for IE apparently uses some watered down aspects of
SMIL, and I believe some of this code works only on IE and close
relatives. A much better approach is to use W3C SMIL 2. If I remember
correctly, the QT player will use a few aspects of SMIL, but it is
rather limited. However the most recent versions of the Real Player
support nearly full W3C SMIL2. It does not matter which browser you use
or if it supports XML, since the SMIL support is built into the Real
player. The Real develper site has tons of information about using SMIL
on the Real player. For example, if the Real player is installed on
even the old Netscape 4.8 which does not support XML and many other
things, the SMIL program works just fine because it is contained within
the Real player. You can control a variety of audio, video, text, and
other types of files at precise times. I am not for sure if the Real
Player will stream a .mov file properly(it might), but it is easy
enough to use a .rm video file, and Real has a free encoder for
converting your video files to .rm files at a desired bit rate.

I very much like using SMIL programs in the Real player for complicated
media presentations. The main problem for use on the general web is
that many do not have the Real player installed and likely will not
bother to download it, especially if they are on dialup. However, when
you can expect your viewers to have the Real player installed or you
are using a local network, then using SMIL with the Real player is the
best way to go, at least for me.

SMIL is nice, but it do not have the capabilities of branching a movie
from user input. Of course you can change the language of the player
and chose the next clip accordingly. For instance the short clip is
language english, the medium clip is french, and the long clip is
norwegian.

The problem with SMIL is that it creates a small gap between each
clip. Thats why I use the method of two players, one visible and one
hidden, and swap them at the end of each clip. Then I load the next
clip in the hidden player, and swap ...etc.

Then I see the problem in the "executed objects' cache". IE (at least)
never dismiss an object right after the last reference on it has been
removed. It keeps the object in the "hybernated" state for a period of
time in case if you come back. The exact mechanics of it as well the
other cache methods is a copyrighted stuff of the browser producers.
You may just exceed the allowed amount of activated QuickTime objects
with your movie-to-movie switch (?? a pure speculation). Try to set
each used reference to *null* before to creatre a new one.

The last reply cracked one of the bugs. Thank you.

I removed the visibility=hidden/visible and used only the zindex. Now
it works in Explorer. At least in my explorer. I am very keen to know
is this solved the problem in the SBC/Yahoo DSL browser, can you please
test it for me cw******@yahoo.com?

In the original code I used both visibility and zindex.
document.getElementById(''+id+'').style.visibility =
"visible";
document.getElementById(''+id+'').style.zIndex="2" ;

Removing the visibility solved it, but I am not shure why. Do
"visibility" in IE create a new "instance" of the object, and it fills
up the cache, or...?

Yes, your page now works on the SBC/Yahoo DSL browser(IE6 based) the
same as it does on the most recent Firefox. On both browsers, there is
about 3 to 6 seconds between clips when the blue QT loading screen
appears. My download speed from my own domain usually is about 2.3
Mbps. I timed a 950 MB download from Roxio at 53 seconds, so this is
about the same rate as from my domain. Of course there always can be
some congestion anywhere between me and a server. Anyway, I do not find
the delay between clips long enough to bother me. These days, the
connection between the central US and Europe often is about as fast as
the connection within the US only. I downloaded a program from Finland
at about 2 Mbps a few days ago.

Actually a lot of misterious events happen in IE not only with
QuickTime but also with many plugins having their own graphical
context: Java applets, Flash movies, Real Player movies etc. These
events (crashes or unexpected behavior) happen when you embed them on
the page and trying to handle as regular DHTML elements: visibility,
position, z-index, alpha and so on. It may be some hidden browser's
design failure (like one from above) superimposed by not-so-well
written plugins' interfaces, this is why it's so difficult to spell the
*exact* reason of each particular case.
