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?

Very good call!  BTW, I'm using "audacity" to capture and convert audio to MP3.  Turns out that it stuffs the id3 tags into the MP3.  I hadn't found a way to disable the tag generation in that tool, so I just used "easytag" freeware utility to strip it.
 
 So, the only issue I have is the #    assert self.objid < 65537, 'the number 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.

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.
