Sorry. Try moving the "setup of the gst stream" to after the
"initialisation of pygame".
The "setup of the gst stream" are the lines:
# grab a frame from camera to file
pipeline = gst.parse_launch('v4l2src ! ffmpegcolorspace ! jpegenc !
filesink location=/tmp/pippypic.jpg')
pipeline.set_state(gst.STATE_PLAYING)
The "initialisation of pygame" is the line:
# start using pygame
pygame.init()
Moving one beyond the other means to change the order in which these
operations occur. I expect the result will be certain failure, which is
a useful result because it proves the timing is important.

Given your test results of success if more time is wasted, perhaps the
program should retry the read of the file until it works, like this:
# start using pygame
pygame.init()
# turn off cursor
pygame.mouse.set_visible(False)
# create the pygame window and return a Surface object for

Thanks, this is unchanged to what you previously provided. Please
continue to try the change to sleep time. I was not asking for the
stacktrace again, I was advising you how to copy and paste accurately in
future.
You might also try moving the setup of the gst stream to after the
initialisation of pygame. Experiment, and let us know your results.

You can't copy anything in the output panel of Pippy, yes, I know, and I've raised that as a bug. It isn't fixed yet. I can copy from the Pippy program panel.

You can import and export items from the sugar journal with this complicated procedure : Insert a 2nd USB (required to be present for this to work) open the frame (upper right corner with mouse) highlight the desired lines in terminal or browser click the scissors up icon (copy) on the top bar click on the journal icon on to frame move to the bottom left edge of frame right click on clipping icon on the left bottom edge of frame hover on this icon select Keep which appears retract frame bottom bar shows journal and USB icon drag the new clipping listed in the journal icon with mouse to the 2nd USB icon now showing in bottom bar next to journal icon hover over the USB icon remove remove USB from computer running sugar insert USB into another windows or linux computer and drag file on USB to the desktop (or into host system by removing and re-inserting it after exiting sugar) open and copy this file to a paste bin application in your browser Note this same method (drag-drop from a 2nd USB) can be used to export Photos from the sugar record activity and to import to journal of (activity.xo) files if reversed On 12/06/2011 02:51 AM, James Cameron wrote: On Tue, Dec 06, 2011 at 09:26:47AM +0100, laurent bernabe wrote: I can copy paste content from browse activity to terminal activity or pippy activity (there is a special icon in the border which appears), but I didn't manage to use this clipboard content in the host system.

Thank you Alan :) I've progressed ^^
- I've download the version 43 of Pippy and installed it on my
home/Activities folder
- when i restarted emulator, i was able to run XOlympic, Physics,
Playsine and Sequence
- the Camera example still send me an error => (line 35 of pippy_app.py,
in at line "image = pygame.image.load('/tmp/pippypic.jpg') =>
pygame.error : "Unsupported image file"
- the Playwave and GetSoundList both seems to be requiring tam tam edit
activity (which i will download and install) : the stacktrace is too long
for me to copy it hand by hand, as I did not manage to copy/paste the result
