I think that'd be great.  vncrec hasn't been maintained in a long time and
pyvncrecorder would be a welcome update... like the aforementioned eschewing
of a GUI.

Then there's the question of what file format to record in (assuming that
ffmpeg can be used for transcoding into any other formats).  For most screen
captures, lossless encoding doesn't just look better, it ends up being
smaller too (due to large sections of identical colors and typically few
colors).  While it's possible to save in something like x264 or flv
losslessly, it's far, far more efficient to save a gzipped RFB (VNC's
format) data stream.  Trying to convert to something like x264 or flv in
real time is taxing (while modern computers can easily handle this for a
single recording, imagine running 40 instances -- which is what I've had to
do).  By comparison, gzip uses a trivial amount of CPU time.

For video transcoding, instead of a custom tool that can
playback/edit/convert that file (like vncrec does, but very poorly), write
an input filter for ffmpeg so it can read the .vnc files and convert them to
whatever you want.  Then you don't have to worry about what formats you want
to conver to.

[Olivier H. <oli...@wa...>]

What a wonderfull discussion ...

So if i resume ... there's two direction :
- some wants a recording tool (with or without GUI)
- some wants an authoring tool...

It's now time to choose.... I don't think that the same tool can do this two different things.

I love the idea to rename pyvnc2swf to pyvncrecorder.. and i think it sould be something like python remote recorder... because, with a modular architecture, and in the future, we will able to record remote protocols (not only vnc), and output this to several video format.

I'm agree, with other people, to take the lead on this project and "recode" pyvnc2swf in that way.

Authoring tool is a very exciting way too ... but it's not really in my interest to work on this kind of project.. So if someone wants to take the lead on this ... it will be great, and i will happy to collaborate :).

I agree about the GUI. That can be done as a separate project that  
perhaps uses pyvnc code. (I'm a big PyQt fan myself).

About the file formats -- I wasn't saying to support them all, just  
architect it so that others can add more as they like. Once you have  
to support two formats, architecting to support N formats is not a lot  
of extra work. Good design and all that.

Wow, this discussion certainly stirred up some action on the list. :-)

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

Hi Olivier,

Thanks for your reply.  Okay... so first I think
I have to state my opinion about the project:

 * I don't want to touch GUI. Getting involved with GUI is not worthwhile because
   we'd have to spend most of the time for just debugging the interface
   rather than adding or stablizing the core functions.
   (Actually, I think that adding the GUI interface to pyvnc2swf was a mistake.)

 * Depending less external libraries is better. 
   We're currently using only Python and Pygame and we already have
   compatilibty problems (between python 2.3/2.4/2.5 and pygame 1.7/1.8 
   and minor platform issues). If we start using other GUI libraries
   (Tk/Gtk/Qt/Wx or whatever) or crypto/encoding libraries, I'd expect
   a big mess. I personally do not want to get involved with that.

 * Just support a few rock-solid core functions is enough.
   After all, this is a spare-time project. I just want something that is
   simple and working. Nothing fancy. I like a Unixy way.

So there you go. I don't have much desire to take a control of
this project, but this is how I can support it.  After spending
several years on this I'm now realizing my interest is somewhat
shifted.  So if anyone really wants to be ambitious and expand the
whole functionality, go for it and I'll try to help it as much as
possible.  Maybe it's the time to split the project or restart
from scratch.

Personally, I think GUI is not necessarily needed for editing.
Once I was planning to write another tool like edit.py
that can "script" a movie with using Python; you could
write something like this:

  movie = Movie("output.flv")
  movie.add_caption("title")
  movie.wait(10)
  movie.load("a.flv")
  movie.add_caption("this is my desktop.")
  movie.load("b.flv")

Well, the input does not have to be VNC then.
This kind of expansion is tempting and you can go on and on.
But, IMO it's better to stick with a few de-facto standard
(actually, fewer is better!) formats to keep the task manageable.

I've seen a quite few open source projects which have got
a really ambitious plan and never be finished.

I think mp4 is enough... further encodings/conversions can be made
with ffmpeg and mencoder.

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

Hi,

I contributed with a few things for pyvnc2swf including the flv output.  Yusuke was responsable for making it work properly, because unfortunately python is not my world.

I've been thinking for a while in creating a new application in Java specially for editing and saving recordings in different formats.  There are so many open source libraries in Java, including libraries for working with Flash files.
There is one special project that I think is really cool:  TeleTeachingTool 
It was developed and it's been used in a university in Germany.  It allows broadcast of the screen, audio and optionally from a camera. It's been used to record long lectures and the result seems very good.  It can save the recordings in flash with thumbnails created automatically.
It could be improved to save in FLV format also.
But what I really miss is an application for postprocessing the recording, that allows editing, merging, cutting, including text and sound, etc, with a good GUI.
The recording can be done with pvnc2swf, vncrec, TeleTeachingTool or any other tool. There could be an effort to create an efficient recorder but in my opinion we miss a postprocessing tool that is not tied with it's own recorder.

Luis Fernando

Interressed??? Maybe yes and maybe not...

In fact in the last days, i was thinking about a complete rewriting of pyvnc2swf ... to feet my special desire.. which looks like more a tool called pyvnc2FLV!.

In fact ... the compliency with other format will be easy to do (thanks to object model and python) ... But i think that if pyvnc2swf firstly become a tool for record and stream vlc session in flv format, it will be great and a good beginning!!

With help of others .... we can manage this kind of evolution.. Don't know because we have to establish a wishlist of what user wants of pyvnc2swf to get it involved... If this should lead to two different tools, new tools will emerge from pyvnc2swf.

So ... why don't we use this thread to discut about the future of pyvnc2swf and establish a wishlist?

I begin :

- safe file writer (every frames is write before the tool quit on a SIGINT or SIGTERM...).
- full flv support (cue points, keyframes)
- streaming (flv?, gstreamer?)
- better performance
- remove GUI from the pyvnc2swf core (we can write later a GUI when all in the command-line is ok and it remove also dependencies to useless packages for frame recording)
- removing the d3des.py and use something like pyCrypto for encryption purpose
- write more readable code (and use correct indentation (pyvnc2swf is indent with 2 char ... )

As a matter of fact, I'm recently getting less keen on this project.
It's not like that I completely lost my interest, but simply it's not in
my top priority anymore. Maybe it changes in future, or maybe not.

Anyway, my response for these requests are now slow. Sorry!
If someone is still interested in improving this piece of
software, I'd rather hand the project to that person and let them
develop it for suiting their own purposes. 

So, Olivier, aren't you interested in taking on this project?
Or anyone else? I can give an administrator account.
If you're not inclined to use SourceForge, it's okay to move

Currently the main page of vnc2swf is hosted on my personal page,
so I can change that to point some other sites too.
(I'm eager to make the transision smooth to avoid users' confusion.)

Please let me know if anyone is interested.

Another question, is there a way to get a png image preview, or the first image frame of the flv?

interesting .. it's a way to consider for the future of pyvnc2swf .. 
Unfortunately, I do not know the desires of Euske on the roadmap of the 
product ...

Re: [Vnc2swf-users] How to set FLV meta data (was Re: About FLV output.)

[Olivier H. <oli...@wa...>]

Greetings!

I use flvtool2... with my little patch, when i ask to display metadata i 
have :


$ flvtool2 -P /home/XXXXXXXX/test.flv
---
/home/XXXXXXXX/test.flv:
  framerate: 24
  canSeekToEnd: true
  uselessdatabuff:
  duration: 42


I don't know flvtool++ and i have no time since the end of april to look 
at it....

But can you seek into your produced flv with my patch ?

Re: [Vnc2swf-users] How to set FLV meta data (was Re: About FLV output.)

[The A. <the...@gm...>]

I used pyvnc2swf for a bit, but found that it took far too much CPU time.
Instead, here's what I do now:

1) Use this patched vncrec: http://aur.archlinux.org/packages.php?ID=16265
In addition to simply recording vnc sessions to a log file, it can convert
the recordings to YUV4MPEG (the twibright patch) on stdout (my patch).

2) Use ffmpeg to read the YUV4MPEG stream and write an .flv

A couple of caveats however:
 - vncrec needs an X display (use Xvfb to create a virtual one, but make
sure it's at least as large as your video)
 - flashsv is the lossless video codec that will generally produce smaller
files for screen recordings while maintaining perfect quality
 - if your ffmpeg doesn't have flashsv support and you have to compile from
source, install zlib-devel
 - scaling down the video size with ffmpeg will often result in a larger
file size (due to the added anti-aliasing), for web-based playback, you can
save bandwidth by having a swf player scale the video down.

Re: [Vnc2swf-users] How to set FLV meta data (was Re: About FLV output.)

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

Folks,

FLV "keyframes" meta data apparently is not being set correctly, even after updating and patching flvtool++-1.1.7. It may be useful to us to ask the author of that tool for a fix. As a result, steaming seeks is not possible. Can others corroborate this finding?

Thanks,
OSC

Re: [Vnc2swf-users] How to set FLV meta data (was Re: About FLV output.)

[Olivier H. <oli...@wa...>]

Greetings!

Yes, the resulted diff shows a minimal workaround to add some metadata 
to the resulting flv (in fact framerate and duration). These one are 
needed, otherwise, produced flv files are not correctly read with flv 
players (such as FlowPlayer).

But it's still 'experimental'. And it will be nice to insert all 
metadata like flvtool++ or flvtool2 does. On the other side, flvtool++ 
or flvtool2 are post treatment tool. And, more your flv file is heavy, 
more your post treatment is long...

In an ideal world, there should be inclusion of all the metadata (such 
as flvtool + +) at creation time of the flv by vnc2swf .... Still work 
to do!

If you're interested by this, read the following documentation :

http://osflash.org/flv
http://pyamf.org/

The result of this, was being able to use the vnc2swf-recorder script to output .flv reading from a streaming stdin input. However the resulting output files contained blank frames. Seeing that v.0.10.0 swf.py had the updates to write out the meta-data for .flv formats, I attempted to simply update this file with the diff, but with the same bad result as before. Below is an approximate diff.

It will create the flv meta data, but does not write the correct height meta-data value either because pyvnc2swf writes it incorrectly (see swf.py use of 'rect' in FLVWriter), or because flvtool++.cpp does uses an incorrect algorithm to read it. The diff resolves this.

[Vnc2swf-users] How to set FLV meta data (was Re: About FLV output.)

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

Folks,

I updated __init__.py and commented out import play, and that got me further, so I could at least test. The result of this, was being able to use the vnc2swf-recorder script to output .flv reading from a streaming stdin input. However the resulting output files contained blank frames. Seeing that v.0.10.0 swf.py had the updates to write out the meta-data for .flv formats, I attempted to simply update this file with the diff, but with the same bad result as before. Below is an approximate diff. 

"flvtool++" (v.1.1) apparently is a work around for this situation. It will create the flv meta data, but does not write the correct height meta-data value either because pyvnc2swf writes it incorrectly (see swf.py use of 'rect' in FLVWriter), or because flvtool++.cpp does uses an incorrect algorithm to read it. The diff resolves this.

Thanks

It complains pygame is not installed. Is there a version that uses PIL instead, or is there a setup option to set it to use PIL?

Thanks

Re: [Vnc2swf-users] About FLV output.

[Olivier H. <oli...@wa...>]

The attached tarball has a setup.py that respect standard python 
distribution style.

Run

python setup.py build
python setup.py install

You can have some help by running

'python setup.py --help' or 'python setup.py --help [command name]'

Forget the old makefile. I leave it here for euske.

Olivier.

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

Greets Olivier,

Just a few requests. I would like to test it out, but am not able to get it into an installed state. I tried to run setup.py, but it seems to output usage along the way instead of actually performing an install. I was not able to use your package, as make fails as well. Could you please update so that it is compatible with the current build system? Also, I have a target system that I use for installation, so the setup/make would need an option to install into a target directory instead of into a system. I can take your work and figure out how to get it completely installed, but not everyone has the time or desire to go to that level of energy output. Also, I am beginner level with Python, which makes it less accessible.

Thanks,
OSC

[Vnc2swf-users] About FLV output.

[Olivier H. <oli...@wa...>]

Hi all,

Vnc2swf can produce FLV. But produced files present some drawbacks.

- files has only one keyframe (also report a few weeks ago),
- files has no metadata. This means that support of pyvnc2swf FLV files 
is not complete for most FLV players (impossible to scroll, total record 
time is not available (a good example : test your pyvnc2swf FlV in 
FlowPlayer)).

I attach a tarball containing some modifications:

- add a '-k' option to specify the keyframe rate
- Add meta data on the produced flv.

Note that I also repackage pyvnc2swf to be more pythonic. Vnc2swf 
scripts, edit and play are replaced by scripts vnc2swf-recorder, 
vnc2swf-editor and vnc2swf player. The distribution is now built and 
installed with setuptools.

The Cli interface was successfully tested on Ubuntu 8.04 and Debian Lenny.

Also note that I did not (and do not want to) install python-tk. I paid 
attention to add some options in the GUI. But these changes are not yet 
tested,.

I leave to Euske or others to test and commit these changes.

Regards,

Olivier Hervieu.
