[Vnc2swf-users] Re: FW: [Pyro-users] trouble with pyvnc2swf/pyrobot combination

[Andrea F. <ak...@be...>]

Thanks, Doug. I appreciate the after hours support. Once again, you've 
steered me in the right direction.

I do not have any trouble recording a blank session or a session where 
I'm opening other memory-intensive programs. I have a newer computer 
running FC4.

Interestingly I downloaded pyvnc2swf 0.7.0 and got a different error:

Traceback (most recent call last):
  File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__
    return self.func(*args)

    self.client.loop()
  File "vnc2swf.py", line 84, in loop
    if not self.loop1(): break

    assert self.objid < 65536, 'the number of objects exceeded the limit!'
AssertionError: the number of objects exceeded the limit!

There are several references to this problem in the vnc2swf archives; 
using video mode is recommended. I was able to use video mode to make 
the recording in 0.7.0 and 0.8.2.

[Vnc2swf-users] Re: [Pyro-users] trouble with pyvnc2swf/pyrobot combination

[<db...@br...>]

Andrea,

I just tried this, and it worked for me under Fedora Core 4, pyvnc2swf
0.7.0, with the standard vnc 4.1.1-10.1. I notice that I am using an olde=
r
pyvnc2swf than you. I'll try the new version and report back if it fails.
I followed the directions at (which I assume that you did too):

http://pyrorobotics.org/?page=3DPyroHowtoVideo

Here is how I ran vnc2swf:

$ python vnc2swf.py
Using pygame 1.6.2
Connected: 127.0.0.1:5901, preferred_encoding=3D(0,)
VNC Screen: size=3D1024x768, name=3D'saliva.brynmawr.edu:1 (dblank)'
Output movie size: 1024x768
Creating movie: '/home/dblank/pyvnc2swf-0.7.0/test.swf': version=3D5,
size=3D1024x768, framerate=3D12.0, compression=3DNone

$ ls -al test.swf
-rw-rw-r--  1 dblank dblank 4876006 Apr 14 00:04 test.swf

Do you get this same error if you just record nothing for a few minutes
(eg, without running Pyro?) My CPU was pegged at 100% running a simulatio=
n
with camera, sonar, etc. with a 1024x768 VNC, but it worked. I didn't
capture the sound, though. My computer is about 5 years old, so it isn't =
a
very powerful computer, and has a single CPU.

I suspect that the error doesn't have anything to do with the Python-base=
d
robot software, but I could be wrong. Let us know under what situations i=
t
works, and when it doesn't.

[Vnc2swf-users] pyvnc2swf fpstack assertion error

[Andrea F. <ak...@be...>]

I am trying to make a video recording a Pyro robotics simulation using 
pyvnc2swf. It always stalls between the first and second minute, and I 
get the following trace:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__
    return self.func(*args)

    self.client.close()
  File "/home/andrea/pyro/pyvnc2swf-0.8.2/rfb.py", line 525, in close
    RFBProxy.close(self)
  File "/home/andrea/pyro/pyvnc2swf-0.8.2/rfb.py", line 463, in close
    self.fb.close()
  File "/home/andrea/pyro/pyvnc2swf-0.8.2/rfb.py", line 814, in close
    self.stream.close()

    assert not self.fpstack, 'nonempty fpstack: %r' % self.fpstack
AssertionError: nonempty fpstack: [<open file 'output.swf', mode 'wb' at 
0xb7c732f0>]

I can stop recording before this happens and create .swf and html files, 
although the second time through the loop the graphics don't refresh 
properly. I can record the session without starting Pyro. I thought it 
might be a permission problem and added full r/w permissions to any file 
and directory related to my Pyro session (did not help), but since I can 
create the files if they're very short, this should not be related. I'm 
using the default shape mode to record, and have set up the session 
exactly as in the instructions.

I ran it with the debug option, but couldn't discern anything from the 
log files.

Has anyone seen this problem? I've searched the Pyrobot, python, and 
pyvnc2swf archives/websites and have had no luck on Google - I'm not 
really sure what I'm looking for, though. I have also dropped a note to 
Pyrobot users.

Thanks.
Andrea

Re: [Vnc2swf-users] pyvnc2swf-0.8.2 is released

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

When the screen changes alot the video format may be a better alternative.
SWF has that limit for the number of available object ids.
A solution for this might be to reset the object ids on keyframes (when all objects are removed from the stage and the ones visible are inserted back in).
Yusuke, is this possible and how hard would it be to implement this?

 Any chance of changing this as it restricts one from creating a long webcast.  Even though .swf has limitations, your vnc editting tools seem to do fine and run really well through the browser even on 1 hour webcasts.

Maybe. But now we start reusing object ids that exceed 65536, 
which might cause an unexpected effect. Once you convert the movie to
SWFVideo format (via edit.py), it may be okay though...

 The best luck I've had with  recording long webcasts  (1+hour meetings) is using the swf recorder.  If I record the vnc format I usually run into the editor problems below.

There's a bunch of ID3 tag editors.
But probably it's easier for us if you can send that mp3 file off the list, 
so that I can figure out the problem.
No, the mp3 should be trimmed if it's longer than the video.

 I didn't save the MP3, but I can try to regenerate one using Audacity.  I have seen this failure before.  I'll ship you a copy once I reproduce it.

I failed to replay this error.
Does this occur every time?

 Not sure about this exact error.  I have had problems when i tried using vnc format.  I can create another webcast and see if I can reproduce it.  If I do, I'll try and send it your way.

Good news, I was trying to save you failing MP3 files when I decided to try
an ID3 tag editor.  Sure enough, removing the ID3 tags cleared up my
failures.  Very good call!  BTW, I'm using "audacity" to capture and conver=
t
audio to MP3.  Turns out that it stuffs the id3 tags into the MP3.  I hadn'=
t

So, the only issue I have is the #    assert self.objid < 65537, 'the numbe=
r
of objects exceeded the limit!'
Any chance of changing this as it restricts one from creating a long
webcast.  Even though .swf has limitations, your vnc editting tools seem to
do fine and run really well through the browser even on 1 hour webcasts.

The best luck I've had with  recording long webcasts  (1+hour meetings) is
using the swf recorder.  If I record the vnc format I usually run into the
editor problems below.

I didn't save the MP3, but I can try to regenerate one using Audacity.  I
have seen this failure before.  I'll ship you a copy once I reproduce it.

Not sure about this exact error.  I have had problems when i tried using vn=
c
format.  I can create another webcast and see if I can reproduce it.  If I
do, I'll try and send it your way.

yes i tried -Vc (it's the same as -t video -c i guess?). it's still pretty
big.

i don't find the swf specification anywhere but i could imagine the shape
encoded swfs simply store rectangular bitmap areas which get drawn where
something has changed on the screen. couldn't shape encoded swfs use some
aggressive jpg compression then for these bitmaps? or are they already
compressed with something like rle and jpg wouldn't make much difference?

could video encoded swfs use sorensen or something like that?

Did you try adding -Vc option in edit.py command?
It should reduce the file size a lot.
It's hard to control the compression ratio of swf in a way that jpg or mpg do,
because a swf file is more like a programming language for animation.

Maybe. But now we start reusing object ids that exceed 65536,
which might cause an unexpected effect. Once you convert the movie to
SWFVideo format (via edit.py), it may be okay though...

There's a bunch of ID3 tag editors.
But probably it's easier for us if you can send that mp3 file off the list,
so that I can figure out the problem.
No, the mp3 should be trimmed if it's longer than the video.

How do you edit MP3's.  BTW, I think this might have something to do with
the length of the MP3.  I think if the MP3 is slightly longer than the
video, this causes  problems.

[Vnc2swf-users] great tool! ...file size optimize?

[horace <hor...@gm...>]

hello,

i came across this tool yesterday and find it awesome! great job!



i have some questions...

i use it on windows. when i converted the swf to mpg with edit.py the mouse
cursor was missing in the mpg. is this normal?

would there be a way to reduce the swf sizes some more? i don't really know
how the generated swfs work but wouldn't it be possible to add an option fo=
r
some lossy jpg compression or something like that? what compression do the
video type swfs currently use?

i noticed that much smaller sizes can be achieved by converting the swf to
mpg and then to mpg4 but swf would be much superior for web based tutorials
if the filesize could be optimized better.

This is the current limitation of vnc2swf.
I might provide some workaround in future.

I'm wondering if there's any ID3 tag in the mp3 file.
Remove them first and then retry.

Ok, this is weird, because msg 4 is not defined in
the RFB protocol manual I currently have.
Which VNC server did you use? (and its version?)

I gave 0.8.2 a shot but still have a lot of problems:

Line 428 of swf.pyc
I always hit this assertion when I'm recording a long meeting ~ 1hour.

I recorded a vnc version of a session with audio, when I try to edit the
audio in I get:

[Vnc2swf-users] pyvnc2swf-0.8.2 is released

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

Hi folks,

Finally I had a time to release pyvnc2swf-0.8.2...
This is a bugfix release, including a small patch
for the mouse pointer problems.

http://www.unixuser.org/~euske/vnc2swf/pyvnc2swf-0.8.2.tar.gz

Thanks,
Yusuke

Re: [Vnc2swf-users] Broken Pointers

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

Hi Bruce,

Thanks for reporting. I think I fixed this bug, so
I am going to release the next version soon. Very soon.

If it still doesn't work, or can't wait the upcoming version, try
adding -N option to make it handle the pointer in a traditional
way.

No, you don't have to split the mp3 file. 
Instead, you could limit the frames to output into one file.
Try:

$ edit.py -f0-10000      -o Chapter1-1.swf -a Raw1.mp3 Raw1.swf
$ edit.py -f10000-20000  -o Chapter1-2.swf -a Raw1.mp3 Raw1.swf
$ edit.py -f20000-30000  -o Chapter1-3.swf -a Raw1.mp3 Raw1.swf
...

Maybe creating some simple split utility in future might be good.

Re: [Vnc2swf-users] Stop recording from other app

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

I don't know how to send unix-like signals on Windows.  Probably,
on Windows, it may not suitable to call other processes as
functions like Unix. If you could convert the graphical version of
pyvnc2swf including Tkinter to an exe, it would be still great.

[Vnc2swf-users] Broken Pointers

[Bruce C. <bru...@ch...>]

Ever since the efforts began to fix the pointers displaying badly for folks. 
They have been broken for me.

The last version of pyvnc2swf to work properly was 0.7.2, every version from 
that point on has had weird pointer shapes for me.

Is there something I can do to get these pointers working in the newer 
versions the way they did in the older versions.

I am using SuSE 10.0 with x11vnc.

[Vnc2swf-users] limit exceeded?

[Albert C. <alb...@co...>]

Hi,

I used pyvnc2swf to record a video tutorial.  Initially it was too long 
(1 hour), so I split it up into 4 chapters, and decided I could cut down 
on the time by adding audio to it instead of using text.  However, when 
I did this:

edit.py -o Chapter1.swf -a Raw1.mp3 Raw1.swf

After all the dots, it prints this:

So then I decided to split the mp3 file into 3 files (each 3-5 minutes 
long).  I ran this:

edit.py -o Chapter1.swf -a Raw1_1.mp3 -a Raw1_2.mp3 -a Raw1_3.mp3 Raw1.swf

However, I got the same results.  Anybody got any ideas on how to fix 
this?  Raw1.swf is 24.1 MB.  Is it the swf file that's too big?

[Vnc2swf-users] Stop recording from other app

[Andy B. <ab...@gm...>]

Hi,

I converted pyvnc2swf to a dos exe using py2exe.
Now I would like to create a windows GUI and use pyvnc2swf as command line
tool.
Starting the recording is no problem but I don't know how I could stop it
since it requires
me to manually press "Ctr-C" in the dos window to do that.

Any idea how this could be achieved?
Does anybody know if there is a command I could send to the dos window to
simulate "Ctr-C" key press?


Thanks for helping : )

I hope to find some time to have a look at this tool. A few years ago, 
one of the researchers of my team developped a tool called econf 
(econf.sourceforge.net) to also record courses based on Java Media 
Framework, but I stopped using it because it requires the installation 
of tools on the student's browser. Flash has the advantage of being 
installed almost everywhere.

If someone has suggestions to reduce the number of bytes of a SWF file 
without affecting the quality, I'm interested.

Best regards,


Olivier

Re: [Vnc2swf-users] size of SWF files

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

Hi,

This is a SWF (Flash) limit.
Try encondig as video instead of shape, this might solve your problem.
I also suggest taking a look at http://teleteaching.uni-trier.de/news.en.html for recording lectures.
By the way, the TeleTeaching Tool recordings are based on vnc with some small changes to reduce the number of bytes and increase throughput. Maybe pvnc2swf could be adapted to also read ttt files.
