[Vnc2swf-users] Bug in vnclog recordings

[<lfk...@ya...>]

Hi,=0A=0AI found the reason for the timing problem in vnclog recordings.=0A=
When recording using type shape or video, every framebuffer update (screen =
update) creates the appropriate number of frames using the time it finished=
 processing the update (finish_update function of RFBProxy class) as the ti=
mestamp of the update.=0ABut when recording with type vnc, the timestamp us=
ed is the time of the request for update (request_update function of RFBNet=
workClientForRecording class).  But that's not a good timestamp, since we d=
on't know how long the server will take to answer the request.=0AActually, =
both are taking the wrong timestamp.=0AIn my opinion the correct timestamp =
should be the moment the client starts receiving the framebuffer update bec=
ause that's the closest to the moment that the server actually checked the =
screen.=0AThe problem is most noticeable when there are none or just a few =
interactions (keyboard and mouse movements). When the mouse moves alot the =
server is constantly sending an update so the difference in timestamp is no=
t noticeable.=0AAnother problem lies in function update_screen of RFBMovieC=
onverter class (rfb.py).  Given a timestamp, it should first create empty f=
rames to catchup the elapsed time and only after that it should insert a fr=
ame with the framebuffer update. Currently it's in the other way around.  T=
his is used in vnclog playback.   SWF recordings use a different class whic=
h is currently working correctly.=0A=0AYusuki, can you check this out for u=
