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? _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

I'm setting up a logging system based on VNC. Vnc2swf sounded like a great way to go, except that swf encoding uses way too much CPU time. Instead, I use vncrec to save the rfb stream to a file. With CopyRect encoding, the files aren't unmanageably large, but pyvnc2swf's edit.pycomplains about unrecognized "CopyRect" encoding. So now I switched to using "vncrec -encodings raw". To keep file size down, I had to modify vncrec to allow me to write to stdout, so I can pipe it to gzip. To my surprise, gzip -9 takes <1% CPU, while pyvnc2swf takes ~80% CPU ( 3.2GHz Xeon)... both result in about the same file size. Anyway, it means that I end up with log files like: logfile.vnc.gz. I can review them with something like: zcat logfile.vnc.gz | vncrec -play - (since I've modified it to also allow reading from stdin). But with 4 hour log files, I need seekable and pausable playback. edit.py to the rescue? Almost: edit.py can't read from stdin either :( When I pipe a raw vnc stream to it, I get: # zcat logfile.vnc.gz | edit.py -o logfile.swf - Using pygame 1.7.1release RangeError: -1: must be in 0...-1 If I instead use a fifo, I get: # zcat logfile.vnc.gz > fifo.vnc & # edit.py -o logfile.swf fifo.vnc Traceback .... [snip] IOError: [Errno 29] Illegal seek I'd really like to avoid having to expand the already massive logfile.vnc.gzinto an uncompressed, raw rfb data stream before running edit.py. Has anyone found a way to make edit.py support reading an rfb stream from stdin? -- http://theamigo.blogspot.com |

Hi! I tried converting a swf file (with only vector graphics in it) into avi, mpg and flv. In the resulting media file, I always get a black screen, but the sound does play. Can vnc2swf render the vector graphics part of a swf file? Many tools for windows can do it, rendering the vector graphics to video on a frame by frame basis. My question is, can vnc2swf do it as well? If not, does anyone know a commandline based linux tool that does this, free or commercial? Regards, Gabriel |

Hi Andy, Sorry for the late response. So, if you are willing to take over the probject, could you give me your Sourceforge account name (off the list)? I'll make you co-admin of the project. Also I'm going to upload things that are currently hosted on unixuser.org to the sf server (or cvs) so you can make changes.

I remember pymedia was once a bit buggy and they crashed unless you pass them proper parameters. To be honest, I am not sure if I used it properly in pyvnc2swf, as I just accepted the code sent by someone else without understanding what's going on. This is my bad. I hope someone who has better understanding of pymedia can fix that part... Unfortunately, I am losing an interest of the project these days. Anyone is interested in taking over this project will be welcomed.

It's actually an unfixed bug in pygame... ---------- Forwarded message ---------- From: Kristian Erik Hermansen <kri...@gm...> Date: Nov 30, 2007 3:13 AM Subject: BUG: crafted pygame input can cause segfault To: pyg...@se... I filed a bug with Ubuntu, so I will just link you to there. https://bugs.launchpad.net/ubuntu/+source/pygame/+bug/172812 The issue can be recreated every time, and only with certain input files. I was utilizing vnc2swf's edit.py, which requires pygame, to convert into MPG video. This is when the SEGFAULT happened. Another input video of shorter length was converted perfectly fine... -- Kristian Erik Hermansen "I have no special talent.

Perhaps I could help here too (I arch/develop/code in Python professionally for many years so far after being sold to C++ before). I would like also to ask Yusuke or whoever maintains the website to include info about flowplayer. This is quite a common task to present already made screencasts. I have spend a lot of time trying to find the open source solution (and found it indirectly - BTW none of google multiple queries I tried brought me to the site). Perhaps I did not have enough luck :-). Cheers, Andy |

Hi, As far as I remember this problem is related to Adobe Flash Player security which started (on version 8) to show this message when a javascript tries to access the embedded flash animation or video, when the html file is loaded directly (without http). The thing is that currently the navigation is done using javascript, not flash.

The SWF generated by vn2swf are older format. You can get them in MPEG using the convert.py script, iirc.

Hi, I have a good news. After a longer research I found the open source flash skin tool. unfortunately the JS seekbar does not work for me - I need a native Flash solution. And here you go: http://flowplayer.org/ . there is another resource here too: http://scott.yang.id.au/2006/07/flash-video-ffmpeg-flowplayer There some things to overcome yet - for some reason ffmpeg chokes on SWF generated vnc2swf during the convertion to FLV in turn. At the same time FLV are somehow not compatible with http://flowplayer.org/ itslef. I was able to see the screen cast with generating FLV via the mpeg stage. It is fresh, I am still working on the procedure. I will keep you posted. Cheers, Andy |
