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

From: Hao, X. <hao...@gm...> - 2008-06-17 07:48:03

hi, all
I used python version vnc2swf to record screen for long time(about sevral
hours), but vnc2swf would exit unusually, and can not record anything. does
anyone else met this issue?
BTW: my OS is 64bits RHEL5.

Best Regards

Due to the limitation of frames in swf file, pyvnc2swf cannot
record movies that are more than 1.5 hours (assuming the recording
rate is 12 frames/sec, 65536/12 = 5461 seconds maximum.) You
should chop the recording into separate sessions. 

Recording it into another format directly, such as mpeg or flv,
could create a longer movie, but I didn't test the program with a
recording more than 30 min.

Thanks for your clear comments, however, I set the framerate to 5, but it
still exit unusually before three hours.

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:

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,
would you please speci what's command and what other tools should be
install, thanks!

I set framerate=5, record would exit exception in 10 min, and swf file is
8.2M, nothing to record. The following is error info.

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...
