I try it on different pc same result. The receiving side only recieves black video images but I can see my video locally.
Comment 2 Frank Schaefer 2010-09-20 20:04:50 UTC
The video device code is ok, so changing component to "yahoo plugin".

If possible, check the error logs on receiving part and see if you can't find something about missing 'jasper' program. On linux that is ~/.xsession-errors, don't know where they're located on windows. You might also have to run kdebugdialog and enable logging for Yahoo raw data.

Currently jasper program is needed to convert yahoo webcam images to something suitable. Hopefully a newer version will try to use the jasper libraries directly. There is a little bit of a discussion if that jasper library should be mandatory or not on windows boxes.

Ah, I think that you could try for presence of jasper program, on the windows box, by trying a 'Invite to view your webcam'

SVN commit 1217895 by rkcosta:

Use libjasper instead of relying on the external jasper program.

From the original ReviewBoard description:

  I saw that for yahoo - webcam images are converted by running an
  external program. Personally I am not ok with this since running an
  external program every 0.X seconds is a bit expensive. Also, not to
  mention using disk files (at least pushing directly into the program
  and reading its output would have been better).

  Also - I saw that inviteWebcam action was checking for presence of
  jasper program - but requestWebcam should also have done that. Not
  to mention that if a yahoo contact just invites you to see his cam,
  you might get a feedback of missing program after accepting to
  invitation. Not necessarily a big deal, though.

rostacs, can you update to 4.6.1 when it's released and check if your issue has been solved? Everything indicates it has, but if you still experience it, please reopen the report.
