[Vnc2swf-users] Generated movie sometimes does not fully play.

[Neal H. <nh...@do...>]

Hi,

I'm using pyvncswf (0.9.3) to record my normal lectures.  I think its
great, and the students seem to appreciate it as well.
However, I have been experiencing some problems, and
it might be fairly frequent (I'm not sure about that, yet).

A normal lecture is about 80 minutes long.  In yesterday's
lecture, approximately 85% of the way through, 
the video stops playing (or being updated) but the audio continues to play. 
If you drag the slider forward (toward the right end), you see the video stills, 
but the audio does not play.

I've documented this as much as I can at:

       http://holtz2.carleton.ca/swf/

If you can get a chance to look, I would much appreciate it.
Of course, any other info you require, plaese ask.
For instance
  - recorded on a Fujitsu tablet using Ubuntu Gutsy Gibbon.
  - processed (edit.py) on Feisty Fawn.

Thanks
neal

What do you use for playback? Anytime I try to use the player provided 
with edit.py under Iceweasel on Debian Etch, the browser complains when 
I touch the slider--- and basically prevents me from "sliding around" in 
the doc.

Not saying there's a connection, but...

Hi,  I don't fully understand whats going on with the playback,
but I use Firefox and I guess the built-in plugin (I don't
remember installing anything special, but while my memory
is good, it is short).

When loading the .html as a local file, it is not possible
to control the slider -- I forget the message, but it starts
something like "Adobe player has stopped a potentially unsafe operation"
and then it complains about trying to communicate with a server, which I'm not.

However, when served through a server (such as my local apache
server, or the campus WebCT server), the slider does seem to work.

cheers

Don't know if this is your problem, but I had a similar problem last
semester with lectures.  It was explained to me on this list:

"The issue is due to the size limitation of swf files. An swf file can have a
maximum of 16,000 frames. vnc2swf records at 12 frames per second. The math
for 12 frames per seconds equals about 22mins of recording time before you
hit the max.

see this link for more information:

I was only getting 22 minutes so it might be that it is a different
problem; or, perhaps, you are recording at a different number of
frames per second?

Aaahhhh!

I was recording at 4 frames per second, which is 66 minutes.
That sounds very plausable.   Thank you very much.  
Will research this.
