Acquisition doesn't work on DVCAM nor WEBCAM

Please can you try this command and upload luciole.log file :
luciole -v > luciole.log 2>&1

Luciole starts, than reproduce the Accqusition error, after leave luciole. And upload here the luciole.log file

I have some complementary questions :
Which kind of video card is used ? Ati, nvidia, other ?
Is compiz activated ?

For the webcam is the following command, on a terminal, operates properly ?
gst-launch-0.10 v4l2src ! ffmpegcolorspace ! ximagesink

Salut!
Here is my #1 test result:

Laptop Ubuntu 9.10 64bit,
NvidiaQuadro video card,
Nvidia proprietary driver disabled,
compiz disabled.

The command
  gst-launch-0.10 v4l2src ! ffmpegcolorspace ! ximagesink
activates the webcam correctly.

I created the (attached) log file with the following operations:
- open Luciole with luciole -v > luciole.log 2>&1
- Create new project (webcam)
- Press the luciole button
- Get the scary error message ;-)
- Close the project
- Exit

Thank you very much for your work on this bug.

Thanks for the indo and log.

With this command modified a bit : it still operate ok :

gst-launch-0.10 v4l2src ! ffmpegcolorspace ! xvimagesink

( xvimagesink instead of ximagesink)

After reading the log I think the problem is about xv usage.

Can you return the result of command xvinfo.
and in particular the number of available ports

   Yay! :-)

   I get:

$ gst-launch-0.10 v4l2src ! ffmpegcolorspace ! xvimagesink

(gst-launch-0.10:2804): GLib-WARNING **: g_set_prgname() called multiple times

raffa@raffa-laptop:~$ xvinfo

Ok thanks for the info and command results
We are going on the right direction ;-)
I go to replace xvimagsink by autovideosink or ximagesink .

I go also to look forward the differences between al this xxxSinks stuff.

Did you a correct result with ? :
gst-launch-0.10 v4l2src ! ffmpegcolorspace ! autovideosink

(It's so exciting to chase bugs!) ;-)

   $ gst-launch-0.10 v4l2src ! ffmpegcolorspace ! autovideosink

activates the webcam correctly.

I have the feeling that it works slower than

   $ gst-launch-0.10 v4l2src ! ffmpegcolorspace ! ximagesink

First time I got the "autovideosink" image after 10 seconds, then after 3 seconds like the "ximagesink" one.

But for sure it works!!!

I agree that ximagesink is faster than autovideosink

But when i set ximagesink in luciole the acquisition does not feet in the window ( only a part of the image acquired is show).
So I think I go to use autovideosink. Bur before I'll go to take a look in cheese to know how they do that.

Better to ise autovideosink . I think because it scans the availabe videosink before displaying.

Hi!

Just by curiosity I tried capturing again from webcam in Luciole 0.7.3 (31) on my Ubuntu Karmic laptop (64bit, Intel).
Again, no acquisition was possible.

I tried enabling hardware acceleration (enabling the proprietary nVidia Quadro driver)
This time webcam acquisition worked properly.

I hope this information can be useful.
Ciao

Just to be clear:

The bug is fixed in version 0.8 and I can acquire also with no proprietary driver enabled.

This bug was fixed in the package luciole - 0.8.2-0ubuntu1
