Ian,

Just an FYI,

The presentation played fine on my EL5 thin client running Firefox3.The
seek bar was there BTW. You might try and teach yourself to not say
"uh" so often:). I do the same,,so I know how annoying that gets. Not
trying to be crude,,,just a thought:)..

Take Care,

Barry Cisna

[Vnc2swf-users] playback issues with vnc2swf 0.9.3

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

Hello,

I have recorded a presentation using vnc2swf and I nam having trouble 
with playback on some browsers, some of the time.

I have posted the .swf files here:

http://excess.org/kernel-walkthrough/2008-06-26-pres/
http://excess.org/kernel-walkthrough/2008-06-26-code1/
http://excess.org/kernel-walkthrough/2008-06-26-code2/

The current issue I'm having is with seeking.  On FF3 the seek bar 
donesn't appear at all, on Galeon they appear but sometimes don't allow 
the position to be adjusted properly (they work for me one day, not the 
next).  Is there anything I'm doing that looks incorrect?


Some other issues I was able to work around/ignore:

The first file had major problems after I recorded it: It would stop 
playing after about 22 minutes, I could seek past but the video would be 
frozen.  I worked around that issue by reducing the frame rate to 4 
frames/second (swf-edit -r 4 -R 3 ...)

The second and third files did not have the same problem but when I 
tried reducing the frame rate on the third one it would produce a file 
that was truncated for some reason.

If I include an <img> in the HTML below the swf file the seek bar would 
not appear some of the time.  I (partially) worked around that issue by 
putting the images in separate page and including the video HTML in an 
<iframe>.

I seem to get two seek bars when I try to open the above pages in Safari 
on a Mac (and seeking doesn't work properly).

The pyvnc2swf script seems to consume more and more memory as it is 
recording.  This is the reason I broke the presentation up into 3 parts.


Kind regards,
Ian Ward

Re: [Vnc2swf-users] a possible issue that record for long time

[Matthew T. <ths...@ho...>]

Hi,
Yusuke is correct, what you are seeing is a limitation of the swf format. 16,000 frames is the limit after this limit playback will stop. You can set the framerate to as low as you want but eventually you will hit 16,000 frames and playback will end.

see this kb article for more information on the swf specifications:

http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14437&sliceId=2

Matt

Recording it into another format directly, such as mpeg or flv,

Found this is an issue with the server and polling options. When "Poll Full Screen" is set, movie is complete, without blank areas.

[Vnc2swf-users] Recording is blank until refresh (remote host)

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

Folks,

When initially connecting to remote host VNC Server with vnc2swf.py, the screen is blank until the remote host begins processing WM_PAINT events on windows (e.g. moving the mouse across the desktop, dragging windows, etc). The resulting SWF output has black areas, and is filled in gradually while user interacts with the desktop. I have tried recording using encoding type shape, movie, and vnc, but all has the same result. Is there any way to force a refresh event from the recorder after connecting? I installed Python Imaging Library, Tkinter, and pyvnc2swf-0.9.3 on the client side with server side running TightVNC on Xp.

Thanks,
-OSC

I am using  Vnc2swf for recording.
I want to record particular active window functionality using vnc.

-Both server and client are running on window xp machine.

[Vnc2swf-users] using pyvnc2swf

[Lukasz S. <szy...@gm...>]

I started using this program and I was wondering about following options.

Size of screen:
- My screen is 1280x800 I tried on edit do a -s 0.65 and that made it
big enough to fit on a website. The only thing was that letters on the
actual screen don't look the right size. Is there a different setting
I could use.
I use:
x11vnc -localhost -viewonly -wait 10 -defer 10 &
python ~/Desktop/pyvnc2swf-0.9.3/pyvnc2swf/vnc2swf.py -o in.swf -N -S
'arecord -c 2 -fcd -t wav voice.wav' localhost:0

- How can I make the final swf file not to start automatically in the
browser and not to do the loop.

Thanks. That solved my problem.

Also,
I installed lame codec but I am not sure how to tell ffmpeg about a new codec?
Does ffmpeg need to be precompiled or can I modify some config file or
tell ffmpeg to use my codec?

ffmpeg -i voice.wav -ar 22050 voice.mp3
tried
ffmpeg -i voice.wav -ar 22050 -acodec mp3 voice.mp3
but still writes mp2

Unless there is a different command? Please list any that might appropriate.
Thanks,

Still the same. There was no id3. It prints blank. I then removed the
Title using xmms and I got hex code. But the code still gives the same

I wonder if the generated mp3 file is corrupted.
Did it play okay? What does it shows with the folloing command line?

 $ python mp3.py voice.mp3

If it does not show anything, try removing the ID3 tags with
some existing mp3 tools.

Re: [Vnc2swf-users] [Error] unsupported operand type

[David K. <dav...@gm...>]

I share all this, not as a final solution, but rather a "how to read
the error message" and only respond because no one else had anything for
you. I don't use pyvnc2swf, this is just general python/linux
troubleshooting.

It looks like self.sample_rate is not set, according to the error. The
first thing is to make sure that I am using it correctly, checking all
the command-line parameters, especially those related to MP3s.

I found all the parameters in edit.py:
usage: edit.py
    [-d] [-c] [-t type] [-V] [-f|-F frames] [-a mp3file] [-r framerate]
    [-S mp3sampleskip] [-C WxH+X+Y] [-B blocksize] [-K keyframe]
    [-R framestep] [-s scaling]
    -o outfile.swf file1 file2 ...

    Specify one output filename from the following:
      *.swf: generate a SWF movie.
      *.flv: generate a FLV movie.
      *.mpg: generate a MPEG movie.
      *.png|*.bmp: save snapshots of given frames as "X-nnn.png"
      
    -d: debug mode.
    -c: compression.
    -t {shape,video,mpeg,png,bmp}: specify the output movie type.
    -V: equivalent to -t video. (Flash version7 or above only)
    -f(-F) frames: frames to extract. e.g. 1-2,100-300,310,500-
       -F disables seeking audio.
    -R framestep: frame resampling step (default: 1)
    -s scaling: scale factor (default: 1.0)
    -a filename: attach MP3 file(s). (multiple files can be specified)
    -r framerate: override framerate.
    -B blocksize: (Video mode only) blocksize of video packet (must be a multiple of 16)
    -K keyframe: keyframe interval
    -S N[s]: skip the first N samples (or N seconds) of the sound when the movie starts.
    -C WxH+X+Y: crop a specific area of the movie.
    -b: disable seekbar.
    -l: disable loop.
    -z: make the movie scalable.

So, it seems like some important things are these:
[-a mp3file] [-S mp3sampleskip] 

So, if those didn't solve the problem, I would move on to the code.

The error message is saying that on line 83, None and and integer are
being multiplied (which is not supported, in python None and 0 are
different types of things. NoneType is for things that are not defined)

On Ubuntu I did a search for mp3 related python modules (to see if there
might be a missing dependency) like this:

apt-cache search mp3|grep python

It came up with this list:
python-eyed3 - Python module for id3-tags manipulation
python-mutagen - audio metadata editing library
python-hachoir-metadata - Program to extract metadata using Hachoir library
python-id3 - Python module for id3-tags manipulation
python-kaa-metadata - Media Metadata for Python
python-mmpython - Media Metadata for Python
python-musicbrainz - Second generation incarnation of the CD Index - python bindings
python-osd - Python bindings for X On-Screen Display library
python-pykaraoke - free CDG/MIDI/MPEG karaoke player
python-pymad - Python wrapper to the MPEG Audio Decoder library
python-pynjb - python wrapper for libnjb
python-pysnmp-se - speed enhanced Python SNMP library for agents and managers
python-tagpy - Python module for manipulating tags in music files
python-tksnack - Sound functionality extension to Tcl/Tk and Python/Tkinter - Python library
python-tunepimp - Python bindings for MusicBrainz tagging library


Since the error appears to be related to getting info about the MP3s, or
creating the MP3s in the first place, you may want to try this on the
command-line (on Ubuntu):

sudo apt-get install python-eyed3 python-mmpython python-pymad python-tagpy python-id3 python-mmpython

Just to make sure all the stuff that works with MP3s is installed.
Again, I don't use pyvnc2swf, so this isn't related to actually
looking at it's dependencies, or some intimate knowledge
of pyvnc2swf, specifically, just a step I might take to get it
working quickly.

Also, if you are using linux, I might recommend using the C version at
http://www.unixuser.org/~euske/vnc2swf/

I use it on Ubuntu, with really great results.  It's fast, and worked
right away for me. It says on the main page that it's not as actively
developed, or have as many features, but I really just want a fast,
low-overhead screencast maker, and it works perfectly for that.

I am following:
http://wolphination.com/linux/2006/06/30/how-to-record-videos-of-your-desktop/

and I record stuff using this script:
#!/bin/sh
#aptitude install python-pyvncswf x11vnc
x11vnc -localhost -viewonly -wait 10 -defer 10 & python
~/pyvnc2swf/vnc2swf.py -o tutorial.swf -N -S 'arecord -c 2 -fcd -t wav
voice.wav' localhost:0
ffmpeg -i voice.wav -ar 22050 voice.mp3
python ~/pyvnc2swf/edit.py -o tutorial1.swf -a voice.mp3 tutorial.swf
mv ~/tutorial1.swf ~/tutorial.swf
rm ~/voice.wav
rm ~/voice.mp3
rm ~/tutorial1.html


Any idea why I keep getting this error?

[Vnc2swf-users] ideas for recordwin

[David K. <dav...@gm...>]

Hi,
I'm on Ubuntu Gutsy (7.10) and I couldn't get recordwin to work
correctly. It was clipping the window wrong (seemed to be the right
size, but offset by the difference between top-corner, and
screen-corner, so unusable) and the syntax for x11vnc was wrong (-mouse
is deprecated) so it wouldn't start the vnc server. Also the wait time
for the vnc server didn't work for me, so I increased it.

I wrote a GUI version that asks you for a filename, if not set, and uses
a slightly different method to capture one window, which works better
for me. It requires zenity (included on Ubuntu) for the file-selection
dialog and the "Click Ok when you are finished capturing" , but you can
just set it to a string, or comment it out, and remove the dialog, to
make it behave more like recordwin.

This method also allows you to move the window, and have it be tracked
(It doesn't just clip, it parents the VNC server to the window.) It will
end the capture if you resize, though.

I added a launcher to my menubar, and it works really well, for my purposes.

You can see a demo of it's output here:

[Vnc2swf-users] Nothing but the X server's x in a grey screen

[John F. L. <jf...@ro...>]

Hello,

I've been reading about vnc2swf for years but just tried it out now.

My test .swf has just the grey x server screen  with the immobile 
xserver x in the middle.

I think I need to initialize the x11 server for the vnc session, but 
I've forgotten how to do that.

Can anyone help me?

Thanks in any case.

[Vnc2swf-users] Res: clipping swf / edit.py

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

Hi,

You don't have to move any *.py to python's folder.
If you're using Windows, then you should have an associotion of python executable with with the extension *.py.   If you don't, click with the right mouse button and select Open with...  and then select the python executable.  Also select the check box to make windows remember it.
If the video files are not in the current folder then you must include the path with the filenames.

The command line seems right.  Try to include the -t mpeg option.

Regards,

Luis Fernando

Greetings,
 
clipping:
I love vbc2swf but when i use clipping, and go for like 960x508+7+147 with a total screen of 1280x800 it does the clipping, but the swf file is as big as the total screen, so I get a lot of white background. Did anybody have the same problems?
 
edit.py
and I still haven't figured out how to use edit.py. I guess I have to use the python command line, but if I enter $ edit.py -o out.mpg 11.swf it tells me that I get:
 
FILE "<stdin>", line 1
 
Syntax error, invalid syntax.
 
So what did I write wrong? and do I have to move the edit.py and out and in files to a certain folder within the python24 folder? Or can they be anywhere on the hard disk?

 
Greetings from Helsinki

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

Hi

edit.py doesn't have a user interface.  It's a command line program.
Open the prompt and just run edit.py to see the command options.
Also check http://www.unixuser.org/~euske/vnc2swf/pyvnc2swf.html#edit

Luis Fernando

Hello,

vnc2swf is great stuff und I got it up and running, the only problem is edit.py it just wont open. I wanted to see if i could add an mp3 file, but if I double click on edit.py I can see a black screen appear but the window just closes itself, so I have no chance of working with it. I am using pyvnc2swf-0.9.3.

any ideas?
