Hi Ted and others,
I appreciate your time in sharing R user group experience with my video
player scheme. Over time, I hope to iron out all issues your views
For now I think I have a good solution for flash 10 upgrade issue. See
screenshot "flash10warning.png" for example of flash version error handler
from my Ubantu box - large error message with alternate playback link to the
swf file itself.
My mac plays the video just fine, and the upgrade detect worked just fine
too. The problem that Gad describes may be more complicated. I suspect he is
encountering a security mechanism resulting from my chosen method of flash
version detection. It is a very popular technique called SWFObject
developed by google. To narrow down Gad's problem, I'll request of Gad to
try the following link's test suite and see if he finds some tests that
fail... http://code.google.com/p/swfobject/wiki/test_suite If one or more
of these tests fail, then I can work backward to identify the problem /
solution matrix. The error message he encountered is consistent with my
catch all error (with 15 1-second retry's before finally aborting) for
security related issues and/or transient Internet connectivity errors.
Thanks again for your feedback,
From: Ted Harding [mailto:Ted.Harding at manchester.ac.uk]

AND it works beautfully using FlashPlayer v.9 on Linux too!
This was the version I already had installed when I first failed
to locate the video -- instead seeing the little panel for installing
FlashPlayer, which I ignored, since I already had it, not realising
that it was telling me I should install FlashPhayer 10.
It is now clear that this advice was erroneous, since version 9
in fact works fine!
Furthermore, when (as I previously reported) I did install version 10,
that didn't work either. I later found that version 10 was looking
for versions of Linux libraries which I didn't have; and also that
FlashPlayer no longer worked (e.g.) on the BBC website.
So I re-installed version 9, and everything again worked on the BBC
and for videos in Press reports, etc. But of course still the same
failure for the SFBA video. Now, using the direct URL for the same
video as kindly revealed by Gad, it works and could have worked
It is, therefore, clear that the HTML in the original URL is doing
the wrong thing, by somehow detecting a version < 10 of FlashPlayer
and refusing to cooperate, when this was erroneous.
I (and Jim Porzak and Mike Driscoll) received a private email from
Video director and Multimedia expressionist
Ron @ Lecturemaker <ronf at lecturemaker.com>
(whom I'm adding to the address-list for this mail) which stated:
The video may be hard find, admittedly, if you do not have
version 10 of flash player installed. If you do not have a
recent version of Flash in your web browser, I present a
smallish Adobe image with the words "you do not have
version 10 of flash installed, click to install".
Attached is a screenshot of what you should be seeing at this link
I'll take your feedback from the R User Group list server
as a suggestion to make the "need to update your flash player"
a lot bigger on the screen.
So, message to Ron Fredericks: The video works with version 9.
If (for some reason) it is essential for the original URL to
detect when version 10 is not installed, then there should be
a pointer on the folloowing lines:
"You appear not to have version 10 of Flach Player installed.
If you are using an earlier version, please click on the
following link ..... "
which would take people to the URL provided by Gad, which does work
on earlier versions (well, version 9 at least). Then it would no
longer be the case that "The video may be hard find, admittedly,
if you do not have version 10 of flash player installed."!
My thanks to everyone who hsd helped to delve into this tangle,
and especially to Gad who found where the solution was lurking!
Best wishes to all,
