I have Segmentation fault issue on version 2.0.1
Hadn't on version 1.7.3 the day that i made update kernel 3.16.3 to 3.16.4 also updating guvcview 1.7.3 to 2.0.1 my copy guvcview can't start anymore.
Here are some outputs via term.

On first error, the config dialog stays/hang on screen i can edit stuff, the cam window never open.
the 2nd error "guvcview -r /sdl" both config and cam window close quickly after opened let say closed after 3sec.
I am running,

Hi,
can you do a backtrace with gdb?
Also if you could test with the current git master, it would be great.
I've committed quite a few changes to git so it would be easier for me to debug and for you to test any fixes I make (also this will soon become version 2.0.2).
Regards,
Paulo
Hi, thank you Paulo, just checked with gdb fortunately cam window open just fine.
Strangely after gdb now i can open shortly /guvcview too.
Yet again there are some logs as you can see on term.

The most important to me is that gdm came to show the cam figure. I think to leave as it is for now, i'll use back gdm if this issue appear again. Thank you for telling me about gdm.
Last edit: Nili 2014-11-22
Same bug here... you can see in the screenshot that my vid is not showing.
thanks for any help you can provide

Hi,
You seem to be using version 2.0.0, please upgrade to 2.0.1
version 2.0.0 and earlier suffer from a bug that prevents from working with kernels >= 3.16
Regards,
Paulo
I still have issue too, most of time crash. The issue is like when i start my computer from reboot,the cam works fine, but once opened some videos with player/vlc 2 hours later the cam doesn't work anymore. Crashing both cam window and his config.
Only on first startup seems to work for a few hours.

Just checked the teamviewer webcam, cam on this application working fine all time.
Hi,
The log doesn't give much information, you should increase verbosity:
'guvcview --verbosity=2'
Does the crash happens while recording to file or even in preview mode ?

Nili Hi,
Could you debug the segfault with gdb or valgrind ?
also do you get any video preview at all before the segfault, or just
a black screen.

Paulo

#14Hi again Paulo
No i don't get any video preview, both cam window and config crash before
opening a video image.
No black screen, just cam window tried to open but crash 2 sec after appear.
Only if i restart the system cam show the preview just fine, once the time
clock passed 1 to 3 hour doesn't work anymore with that crash things.
Here are logs provided from valgrind with command "valgrind --tool=memcheck
guvcview --verbosity=2" hope i am doing right because didn't know much for
this tool.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what OS and version you are using. Thanks.
Thank you again,
Kindly regards and many thanks for the support.

#14Hi,
Well valgrind crashed so it doesn't provide any useful information.
what about gdb ?
Also do you think you could test with the latest git version?
just install all of the dependencies:
sudo apt-get install intltool autotools-dev libsdl2-dev libgtk-3-dev
portaudio19-dev libpng12-dev libavcodec-dev libavutil-dev
libv4l-dev libudev-dev libusb-1.0-0-dev libpulse-dev libgsl-dev
get the code:
git clone git://git.code.sf.net/p/guvcview/git-master guvcview-git-master
and build:
cd guvcview-git-master
./bootstrap.sh
make distclean
mkdir build
cd build
../configure --prefix=/usr
make
sudo make install

I have bare minimal system "Crunchbang" testing, really i do not want to
install all those packages you know "spoil my philosophy of being minimal"
:)
pityingly, I can not compiling out this time, I do not want to break because
it is the primary system.
So any other help with gdm command would be a good alternative for me.
Thank you once again for your effort.
Kindly regards,

#14Hi,
2015-01-26 15:50 GMT+00:00 Nili spotnili@users.sf.net:
Since guvcview is a multithreaded app you need some extra commands for
getting a backtrace for all threads.
You would also need the debug symbols (these are stripped when
building debian binary packages), for getting a more readable output,
but since you can't build the code from source, that's out of the
question.
In any case after execution stops and while in the gdb prompt do:
thread apply all bt
this should give a backtrace for all threads.
No, problem.
Actually I have daily built binary packages for git-master in my testing ppa:
https://launchpad.net/~pj-assis/+archive/ubuntu/testing/+packages
These are meant for ubuntu, but I think they should also have all
dependencies met in debian.
There are packages for both 14.04 and 14.10, try the later first, if
there are unmet dependencies then try the first.
Just download and install both guvcview and libguvcview-1.0-1
Please try the backtrace command described above .
Regards,
Paulo

#14I just had another seg fault. What's most curious is that I had shut down guvcview!

Removing any VLC tracert from my system seems to fix my issue, i have no crash anymore. Currently i am using mplayer2/smplayer no issue since a week. I can safely open guvcview without a crash.

have you tried a different audio api:
(no audio)
guvcview --verbosity=2 --audio=none
(pulse --if enabled and pulse server is running)
guvcview --verbosity=2 --audio=pulse
the back-trace doesn't help much, it segfaults when calling
audio_portaudio_list_devices(audio_ctx) but it's not clear on the
reason.
could you please run this through valgrind, it should print some more
information on the reason for the segfault.
Regards,
Paulo

#14--audio=none does give me a GUI to configure, but no video output, and the only way to exit is to Ctrl-Z, then kill -9 the process.
Hi,
make sure you have set the render api:
guvcview --render=sdl2 --audio=none --verbosity=2
and please post me the console output .
also if you could run it through valgrind it would be very helpful:
valgrind guvcview --audio=port --render=sdl2 --verbosity=3
this should help give a better idea of what is going on.
(also make sure to always get the latest code from git)
Best regards,
