The key word here is "synchronized" ...
Ok ... Debian (sid), vnc2swf, both patches for it applied ...
Basically ... launch the vncserver, start a "sox | lame" mp3 encoder,
start the vnc2swf client generate the swf file without error, quit the
client, kill the server ...
But the video is out of sync with the audio :-/
The audio is about 4 seconds behind the video ...
Any idea of what I can do to synchronize them, short of editting the swf?
Below is a log of the commands i've been using to make swf recordings.
By the way, when ever I "mkfifo out.mp3", or "mknod out.mp3 p", as the
patch instructions say to do, the sound always cuts out after the first few
seconds of the resulting swf file. The method shown below does not
have that problem, but it may be worth noting why I cannot get the
recommended instructions to work.
