[Vnc2swf-users] using edit.yp to read from stdin?

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

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?
