Re: [Vnc2swf-users] Installing latest version on Win32

[ciro b. <kr...@ya...>]

Thanks, that looks very promising, I will try it tonight when I'm home. If other people want to try it, it's part of the VNCed distribution at http://vnced.sourceforge.net/ ; they have the current latest version (0.9.3).

Thanks again for your help,

Ciro.

Hi there,
 
I have heard that,you can download the pyvnc2swf-py2exe 
from sourceforge.net,it works well on Windows.

I've tried

[Vnc2swf-users] Res: Res: AssertionError limits recording time

[<lfk...@ya...>]

Hi.

Just for information:
-t shape -> creates rectangular objects similar to updates sent by vnc server. Object limit can be a problem. By default mouse pointer movements doesn't create new objects but just moves it. Creates a swf file.
-t video ->  creates a video stream inside a swf file. Doesn't use rectangular objects. Uses a screen record/playback codec which basically splits the screen in small areas and writes the updates for each area on every frame. Object limit is not a problem since it doesn't create objects. Mouse pointer movements are treated as regular screen updates. Creates a swf file.
-t flv -> creates a video stream in a flv file. Same as -t video except that the container is FLV.  Sound hasn't been implemented in pvnc2swf for this.


Vnc2swf tries to remove updates that get totally covered by other updates between frames (updated rectangle ends up totally behind other rectangles). This is just a basic optimization.
Maybe there could be implemented a better optimization that tries to reduce the number of objects created but this could be complex.

Regards,

Luis Fernando

Thanks for the informative replies. As pointed out by you, I think the
problem was that writing using a tablet creates too many small
objects, causing the limit to be exceeded independent of the frames.

I then tried recording to .vnc format and then converting to .swf with
vnc2swf-edit, and when I use the -V option (video) it seems to work
well. I had not realized that the -t video would still result in .swf,
I thought it meant it would create .flv. I assume this means that
directly recording to .swf with -t video will give the same effect -
namely size limited by number of frames, not objects?

Thanks very much,

Nitin

Re: [Vnc2swf-users] Res: AssertionError limits recording time

[Oscar U. <osc...@pr...>]

Could the source be modified to count the update frames until it's
reached max, then either exit gracefully or start recording to a new
file?  I think that would be a more useful behavior than AssertionError.
I already imagine the answer is yes, but how could we go about this?

One issue with automatic recording to a new file is requesting a new
frame update at the start, otherwise the new film could start out
fragmented.

Re: [Vnc2swf-users] Res: AssertionError limits recording time

[Ian W. <ia...@ex...>]

If the flv recording mode gets around the object limit you might be able
use the method that worked for me:

http://excess.org/article/2008/07/creating-high-resolution-screencasts-vnc2swf/

Maybe change the "vnc2swf -n -o tutorial.swf .." to "vnc2swf -n -o
tutorial.flv .." instead of converting in the next step?  I record audio
separately and use the flv format because the flash player I use
requires flv.

When I used this method (unmodified) I was able to record more than 80
minutes.  However, it might have worked for me because of the really
basic window manager that the presenter used (less rectangles).

[Vnc2swf-users] Res: AssertionError limits recording time

[<lfk...@ya...>]

Hi,

VNC protocol uses rectangles to send screen updates to the client.
When you record or transform into shape format (not video), vnc2swf creates a swf object for each rectangle.  Usually there are many rectangles in each screen update when the screen changes often but there may be none when the screen is not updated.
One thing many people don't realize is that any icon or label that changes very often (such as network connection icon or even the clock with seconds or even msn) and is not related to the recording may be increasing the size of the recording and the number of objects created.
So anything that changes on screen causes a rectangle update.  The size of the rectangle depends on the area changed. It the small areas far apart change, there will be two rectangle updates.  If they are close, there may be just one.
I suggest removing icons that are not necessary while recording.
What I want to say is that frame count is not the only limiting factor.
I think that object count is even more important and it is probably what's been limiting the recordings.
You could try converting to video format, or even to flv (audio not supported yet).
They won't have the object count limit (I think).
Good luck!

Hello,

I am using pyvnc2swf 0.9.2 (from Debian testing) to record lectures in
class (I write on a tablet using Xournal in VNC and record the VNC
session along with audio using the -S option).

After about 30-45 minutes, the program crashes with an error

  File "/usr/share/pyvnc2swf/swf.py", line 784, in newid
    assert self.objid < 65536, 'the number of objects exceeded the limit!'
AssertionError: the number of objects exceeded the limit!

I tried reducing the framerate as suggested in other messages, but
even with a framerate of 3 it still crashed before the end of the
lecture (<50 minutes).

I then tried recording to .vnc format, and it records the whole
lecture, but if I try converting to swf with vnc2swf-edit.py, it again
crashes with the same AssertionError.

One of the previous messages mentioned a maximum of 16000 frames,
which should still give > 5000s at 3fps. Is the above error to do with
frames, or are the VNC changes recorded as objects, which would maybe
make it crash if I wrote too much in one session?

Thanks,

Nitin

Re: [Vnc2swf-users] Record limit to 30 minutes

[Kevin S. C. <ksc...@gm...>]

I think this might be related to a problem I had.  At the default
frame rate, it will only record for about 22 minutes.  This is because
the maximum number of frames allowed in SWF.  For more info:

"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:
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_14437"

If you change the framerate in vnc2pwf though you will be able to
record for a longer period of time without worrying about having to
gracefully exit.

Folks,

Recording via vnc2swf.py to format .swf after 30 minutes causes the swf to be corrupted during later ticks. Is there a way to limit the recording to 30 minutes so that it exits gracefully?

[Vnc2swf-users] Request for Full Framebuffer update

[Oscar U. <osc...@pr...>]

Folks,

My output records have long runs of blank data until the vnc server starts sending framebuffer updates. Is there a way to modify vnc2swf so that when it connects it immediately requests a framebuffer update full?

I forgot it's only an experimental feature I did locally and I
haven't tested it much.  Now I uploaded the changes to CVS,
so here's the instruction:

 1. Install a package called pymedia (www.pymedia.org).

 2. do the following:
	$ cvs -d:pserver:ano...@vn...:/cvsroot/vnc2swf login
	$ cvs -d:pserver:ano...@vn...:/cvsroot/vnc2swf co pyvnc2swf

 3. cd to pyvnc2swf/pyvnc2swf/ directory and you should be able to recording:
	$ ./pyvnc2swf.py -n -o out.mpeg :0

Again, this feature is still pretty much experimental.
I don't have a time to test/check the correctness of the output right now...

"username" is not asked for, and is *not* supported in the vnc rfb protocol, BTW which I think should be expanded to cover it.

Anyway, you ought to look closely at the command line arguments of vnc2swf.py you'll see that you can specify a password from the command line.

Hi,
Im trying to capture of a VNC screen in python but the vnc server

Yes, this article offer to us a method that linking some small flash file
together. Could we set a file named method, the first file named
file_01.swf, when reaching the limitation, vnc2swf can auto close the first
file and continue recording to the second file file_02.swf...

BTW: Yusuke, I noticed you said it can directly recording to mpeg format,

Re: [Vnc2swf-users] Res: playback issues with vnc2swf 0.9.3

[Ian W. <ia...@ex...>]

Hello Luis,

Thank you for your work on the flv code!  The screen recording/playback
mode was the reason I wanted to use pyvnc2swf.  I ran into problems with
pyvnc2swf's built-in playback code and being able to export to flv let
me use an external player, avoiding those issues.

I worked around the lack of audio support by using ffmpeg instead of
mencoder.  mencoder was producing files only mplayer could play, but
ffmpeg worked perfectly.  I used a command like:
  ffmpeg -i video.flv -i voice.mp3 -acodec copy -vcodec copy out.flv

Here is the result:
  http://excess.org/article/2008/07/oclug-june-kernel-walkthrough/

I had to manually clip the audio to match the video, but that's not a
big problem.

The only issue remaining for me is what appears to be a memory leak in
pyvnc2swf during recording.  It would be nice if I could just let it run
for a couple hours without restarting the capture.

I will post some step-by-step instructions to my site and this list some
time soon.

Regards,
Ian

[Vnc2swf-users] Res: playback issues with vnc2swf 0.9.3

[<lfk...@ya...>]

Hi Ian,

Audio in FLV output hasn't been implemented.
Some time ago there were some requests for implementing flv output to pvnc2swf.
I had some spare time so I played with it a bit and managed to make it work.
I sent the modifications to the list to check if that was what they wanted.
Yusuke included it in a new release some time after that.
The flv format allows two types of encoding.  One is for video in general, used by YouTube.
The other was designed for screen recording/playback.  That's the one pvnc2swf uses. And that's why some people
complained that the flv file generated by pvnc2swf didn't play in some players when using flv codec. The problem is 
that the codec being used didn't implement this encoding format.
I had planned to work in the sound part after making sure the video part was ok.
But nobody said anything about it.  Actually after some time some people complained that it didn't play in some players.
So I ended up losing interest in it.
But if there is interest for this I can at least take a look at it again.

Regards,

Luis Fernando

Assunto: Re: [Vnc2swf-users] playback issues with vnc2swf 0.9.3

Now I've run into something else.  When I convert my .swf file to a .flv
file I lose the audio.  I tried adding the audio before converting, at
the same time, and after converting all with the same result.

Is there something I'm missing or has adding audio to flv files not been
implemented?

(I also tried using mencoder to add the audio, which worked with mplayer
but not with other flash players)

Thanks Barry,

I am going to convert all the videos to flash video and use a different 
player.  I was concerned that video quality would be degraded, but it 
looks fine.

I'll pass along your suggestion to Bart.  I would have been a much worse 
presenter than he was!
