[Vnc2swf-users] Cursor pseudo-encoding

[Luis F. K. <lf...@ya...>]

Hi,

Congratulations.  This is a great software.
Now, with the python version, I'm finally able to use it.
I was trying to understand the C version so that I could try to translate it
into java so that I would be able to use it on Windows.  I'm happy that it will
not be necessary.
Trying it out I noticed that the swf file was alot bigger that I expected. 
Even after compression with edit.py. 
Checking the source code, I noticed that the cursor pseudo-encoding is not
used. By using this encoding, the screen (framebuffer) updates are greatly
reduced since  the mouse movements are sent separetely from the desktop.
Otherwise, every mouse movement makes it necessary to update the region under
it.
I think this feature would make this great software even better. Couldn't you
add this to the next release? Or, at least, could you give me some hints and
ideas on how this could be acomplished?

Thank you,

Luis Fernando

Right... I found there's a problem in OSX, too.  Sometimes, I
succeeded :) but not always. Seems like OSX Tkinter modules aren't
that ready for prime time... Until I figure out how to fix this,
please stick with the good old command-line terminal. Thanks.

Actually that's the expected behavior.  pyvnc2swf doesn't provide
a vncviewer-equivalent functionality which the original vnc2swf
has. I assumed many users now will use "Remote desktop" feature
such as WinVNC, x11vnc or GNOME Vino rather than a separate
virtual screen for recording.  But when you prefer to use a
separate screen, I admit this is less convenient, as you would
need to launch a viewer separately to operate.

[Vnc2swf-users] Observations running on OS X

[Dann S. W. <da...@th...>]

I have pyvnc2swf-0.6.4 running on Tiger right now and noticed some 
gotcha's.  In addition to requiring pygame it seems to also require 
pyobjc.  Both are available at the pythonmac.org/packages site.

I believe both Tiger and Panther are running Python 2.3, so make sure 
you get the right packages.

Another issue was that pygame was not found when vnc2swf.py was 
executed.  The files were installed in /Library/Python/2.3/pygame.  Now 
I am not in any way a Python developer, so my work around for this may 
not be correct.  I simply created a symlink to where pygame was located 
in 
/System/Library/Frameworks/Python.framework/Versions/2.3/Extras/lib/python.

The application now worked, but I noticed another issue.  I was not able 
to enter the host name and port in the gui address.  I could enter a 
save location and choose shape, video, vnc.  On a lark I pressed start 
and received the expected error.  The save location popped up again but 
even that would not accept any input.  I had to end up terminating the 
terminal.

Running vnc2swf.py from the command line with all the necessary options 
was successful.

[Vnc2swf-users] pyvnc2swf functionality question

[dann s w. <da...@th...>]

I've been using vnc2swf for about 2 years now, fantastic software.  I 
figured I set to giving pyvnc2swf a go.  I'm running Ubuntu Hoary and 
noticed that when I run pyvnc2swf to connect to the vncserver running on 
the same machine no vnc window pops up like it does when using vnc2swf.

I figured there might be an issue with the versions (I was using 0.6.4) 
so I bumped back to 0.6.2 and it did the same thing.  On a lark I fired 
up a vncviewer session to the same server and it was recorded by pyvnc2swf.

Is this how the sofware is supposed to function?  Unlike vnc2swf you 
don't get a window and have to connecting using vcnviewer?

I do not get any errors when running pyvnc2swf.  I've tried both the 
command line and gui.

Well you can rescale it by using edit.py from command line. 
Try:

	edit.py -o out.swf -s0.5 in.swf

Open up the Vnc server property window,

Re: [Vnc2swf-users] Unsupported server security type: 0

[Yusuke S. <yu...@cs...>]

Hi Markus, sorry for the delayed reply.

I finally figured out the cause of this kinda errors.
(Actually several other people asked about this, too.)

The bottom line:
  Vnc2swf doesn't run with WinVnc 3.3.7 when you're
  running the vnc2swf on the same machine, because
  WinVNC 3.3.7 doesn't allow localhost as a client.

And I've also noticed you get the MemoryError with Vnc 4.1.1
if you didn't set up the Access Control list properly.

To fix this, you simply use Vnc 4 (or 4.1.1), 
and check the "Only accept connections from the local machine" box.
This is at "Connections" tab in the Vnc server property window.

Or you could connect to the target machine remotely from some
other machine, though it might be slower.

Thanks
Yusuke

[Vnc2swf-users] Unsupported server security type: 0

[Markus S. <die...@ya...>]

Hi!

Trying to run vnc2swf on W2k I always get the message
"Unsupported server security type: 0" when I connect
to the server.

Problem occurs with realvnc 3.3.7 and also with tight
vnc.

In the python source there's kind of a password
dialogue but I had not been asked for one.

Thanks for help!
Markus

Re: [Vnc2swf-users] edit.py Option -F

When you edit a movie by adding mp3 files and choosing multiple frames 
at the same time, like "edit.py -a sound.mp3 -f 10-20,40-50",
-f cuts and splices the mp3 stream too. But -F doesn't.

In fact this is equivalent to:

  $ edit.py -f 10-20,40-50 -o tmp.swf in.swf
 and then
  $ edit.py -a sound.mp3 -o out.swf tmp.swf

Does this make sense?

Hi,

I also had the problem with attaching mp3 sound on Windows
XP.

Just adding a binary mode flag to the line 124 of
edit.py(pyvnc2swf-0.6.4) seems to solve the problem.

    fp = file(v)  ->  fp = file(v, "rb")

Yes, I've read that article, too. I agree with you in that we
could have a better open format instead of SWF. For screen
recording, however, perhaps MNG format is more appropriate,
because SVG lacks a bitmap fill support.  But MNG also lacks audio
streaming.  Currently SWF is the only format which supports both
animation and audio, but I am not a zealous advocate of this
format.  Especially I want to use OGG format instead of MP3, which
is currently impossible with SWF.

Here's an interesting comparison between SVG and SWF:

Well, believe or not, I'm definitely pro-open or free format. And
I think adding supports for other formats to pyvnc2swf now is
relatively easy because of its nice redesign ;)
Maybe I can look into those specs this weekend, and figure out
how we could support any of them.

[Vnc2swf-users] Support of SVG or other free formats ?

[MF <mag...@gm...>]

Hi,

I've been playing with vnc2swf for the past few days and would like to
ask if there are plans to support creating SVG files instead of SWF. I'd
like to use this in other projects where the target audience would not
have a flash player and I am concerned about the legal aspects of
reading and creating SWF files, as many may have seen in this recent
article:
http://yro.slashdot.org/article.pl?sid=05/08/29/2339216

Regardless of what the real legal implications of the past, current and
future EULAs or other provisions may be, the mere fact that someone
using vnc2swf has to check and may be liable for potential violations of
them makes it difficult to justify producing any content in SWF format,
particularly when they're tied to corporate interests and the content
itself may not be accessible freely in the longterm. I initially
researched ways to convert to SVG but even reading SWF has legal
implications I can't accept, personally.

Perhaps this is not the place to start a huge "Flash vs. SVG" or
"Gratis, under-NDA vs. Free, Open" endless debate, but I'd like some
indication of the direction vnc2swf would have. I have  aproject in mind
where I could justify some funding to have an SVG version, is this
something others would also chip in ?

Thanks for any *constructive* discussion ;)

Cheers,

Fabian

Re: [Vnc2swf-users] Problems with extracting frames

[Yusuke S. <yu...@cs...>]

Hey, I've just done this. It was pretty easy :)

Now
  $ ./edit.py -f 2-4 -o murks.png
should do exactly what you want.
(generated images will be murks-00000.png, murks-00001.png, murks-00002.png)

The latest version is available from sourceforge cvs.
So if you're interested, just check it out.
I am not sure if I should release this as a newer version though.
How do you think?
