skipping MPG video (Windows XP, SP2)

(or: SMILe in DLL hell)

To answer my own question: it helps to run Ambulant in
compatibility mode
(video PB becomes tolerably smooth)

My other question i still can't answer: has SMIL been used
to coordinate 
video
and (hyper)text in both directions? In my case, text of a
play with 
video of its
performance - i'm trying to use the text in HTML both for
subtitles (and 
stage
directions) and for navigation through the play, and i'm
surprized to 
find NO
such work on the web ..

Have you looked at DAISY books?  They use SMIL to
synchronize audio 
clips with fragments of marked-up text (XHTML, for example),
and often 
you find books with linkbacks in the text, which means that
the text 
elements are wrapped in an anchor pointing to the
corresponding SMIL 
structure.

For example, the SMIL looks like this:

<par id="sync_para_1">
	<text src="file.html#para1"/>
	<audio src="file.wav"
clipBegin="3s" clipEnd="10s"/>
</par>

and the text looks like

<p id="para1">
<a href="file.smil#sync_para_1">This is
paragraph one of the text...blah 
blah..</a></p>

The table of contents for DAISY books is either an HTML or
NCX (XML) 
file, depending on the version of the DAISY standard used. 
Links into 
SMIL are done the same way as above.

What is "Compatibility mode"?

The closest work that I know of is playback of Daisy books
(talking  
books for the blind). These use a SMIL file to control
timing, which  
refers to audio files and html files. Usually the html file
is per  
chapter, with the Daisy player highlighting the paragraph
for which  
the audio currently plays. Clicking on another paragraph
will send  
the SMIL document to the relevant position.

Note that that paragraph is *very* concise, and skips over a
lot of  
the options that Daisy provides (there's lots of different
document  
types with and without audio and text, etc), but it gives
the main idea.

Right, that's close enough, though i'm still surprized
that there's
nothing more; before i went looking around the web, i was
sure that
at least some Shakespeare would be given a SMIL treatment
long ago
(would be interesting for stage directions, role and speaker
id,
video format/compression, bitrate, ..)

About this code, in SMIL:

  <par id="sync_para_1">
     <text src="file.html#para1"/>
     <audio src="file.wav"
clipBegin="3s" clipEnd="10s"/>
 </par>

and in HTML: 

 <p id="para1">
   <a href="file.smil#sync_para_1">This is
paragraph one..</a></p>

yes, i've been struggling with code like this in my demo,
for some
time now, without much progress. Triggering text to appear
as sub-
titles when somebody in the video speaks is simple, but the
other
direction gives me problems. I want to have one SMIL window,
with
two regions, one for text and one for video, so i can't use
   <a href="file.smil#sync_para_1">
in the HTML, because it starts a new player. So, i need to
change
HTML links to SMIL links with the Fragment attribute, which
don't
work .. i tried many variations, and now suspect Ambulant
does not
support Fragments. I now want to get to the bottom of this
with a
very simple example - i want something like this:
http://nl.ijs.si/~damjan/video/Pasijo
n/Demo/fragment/fragment-seq-dumb.smil <http://nl.ijs.si/%7Edamjan/vide
o/Pasijon/Demo/fragment/fragment-seq-dumb.smil>
but under user/menu control
(sorry for the dumb code - i can't get Ambulant to even
repeat a
sequence, as in
http://nl.ijs.si/~damjan/video/Pasijon/Dem
o/fragment/fragment-seq.smil <http://nl.ijs.si/%7Edamjan/video/Pas
ijon/Demo/fragment/fragment-seq.smil>

Anyway, here's how i tried it, by the W3C pages on Fragment
(which
meander, switch examples, and don't explain them well (how
is the
player to decide which <excl> child to display before
anything is
clicked?)
http://nl.ijs.si/~damjan/video/Pasijon/Demo/fr
agment/fragment.smil <http://nl.ijs.si/%7Edamjan/video/Pasijon
/Demo/fragment/fragment.smil>

It seems Ambulant doesn't redirect links in the HTML - it
doesn't
even show the redirections in the status line at the bottom
(and
it doesn't show any <img>, which is at least
understandable) .. 

I'm about to give up on Ambulant .. or is my code really
that dumb?

ANY suggestions, please!

With a grim Smile,

Damjan B.
