Hi, 2015-01-28 2:26 GMT+00:00 vedavata vedavr...@gmail.com: What do you mean by hang up ? Does the control window becomes unresponsive? Yes. And MKV-files is stopped to fiil. From the logs I notice is that the capture ring buffer gets full, this usually means frames are not being encoded fast enough. Guvcview tries to compensate for this, by reducing the frame rate. I tried 30, 25, 20, 15 fps -- the same result: when MVK-files reeaces 2 GB, guvcview hangs up... OK, I'll test this again in another machine. Also the matroska muxer caches audio frames so that matching audio and video packets are stored in the same cluster. I doubt, that AVI is better... :-) It's not, but it's a completely different muxer, it doesn't care about timestamps, so it just writes packages immediately to file. In this case for some reason video frames are not being fed to the muxer, so audio keeps filling the cache. Have you tried reducing the resolution, or fps? Yes. 30, 25, 20, 15 fps... 960, 800, 640 pixels... [On a Core i5 processor.] You should also test with different codecs and with the avi muxer, Yes, tried MPEG2, H264... The same... 2 GB...

Hi. Guvcview debian mantainer choosed a diferent packaging approach. In order to keep some sanity I've changed my ppa to make it compatible.

Re: [Bug 1373221] Re: guvcview crashed with SIGSEGV in get_ctrl_by_id()
Well, the kernel issue is now defintily fixed, so it shouldn't be a problem in the future, libv4l2 can now be disabled, so we can workaround any issues with it. As for libavcodec, they don't offer any garanties on the API, so it usually causes some breakdowns from time to time, but this is true for all aplications. I actually tend to fix things rather quickly, unfurtunately in the case of Ubuntu they can take some time to upgrade, so you are left with a non working version until the next release. For debian it's easier since it's a rolling realease, I just contact the mantainer and he upgrades to the current (fixed) version. In the case of ubuntu, the only option is to use one of my ppa's for 14.10, the current testing version is now working fine, I've fixed all issues with both libavcodec and uvcvideo, so I'll release the new version both in sourceforge and in my stable ppa.

Re: [Bug 1373221] Re: guvcview crashed with SIGSEGV in get_ctrl_by_id()
Hi, So I was finally able to test this in both 32 and 64 bit kernels and while the gspca driver works fine on both (eye toy 2 camera), uvcvideo (logitech c930e) fails on both kernels, increasing the driver verbosity I get: EOF on empty paylod this is consistent with the zero size frames I'm getting in guvcview. So I would say this is definitly a driver issue, I'll try to install the latest media tree to check if this fixes things: http://git.linuxtv.org/cgit.cgi/media_build.git/about/ I think a bug report should be filed against the current ubuntu 14.10 kernel, referring the uvcvideo issues.

Re: [Bug 1373221] Re: guvcview crashed with SIGSEGV in get_ctrl_by_id()
Hi, I've set a workaround for uvcvideo buggy behaviour, I just set the buffer length to the maximum value if bytesused is zero. Anyway this is clearly a bug in uvcvideo since it violates the v4l2 api: http://linuxtv.org/downloads/v4l-dvb-apis/buffer.html You should be able to upgrade from my testing ppa in a few moments (build pending).

Re: [Bug 1373221] Re: guvcview crashed with SIGSEGV in get_ctrl_by_id()
Hi, From the logs guvcview is receiving empty mjpg frames, so it doesn't even tries to decode them. Have you tried setting the format to yuyv ? guvcview --format=yuyv You should also set the nodrop option for the uvcvideo driver (prevents the driver from dropping incomplete frames) Does dmesg prints out anything usefull? Anyway I hope to be able test 14.10 in a couple of hours, so I should be able to run some tests on my own, although with a different camera.

Re: [Bug 1373221] Re: guvcview crashed with SIGSEGV in get_ctrl_by_id()
Hi, So I've just installed ubuntu 14.10 in one of my machines and everything worked has expected. To my surprise even 1.7.3 (installed by default during the upgrade) is working without issues. I've run some tests with the latest git master, and all formats are working OK, I couldn't replicate your issues. True that I used a gspca camera, but unless these are caused by a uvcvideo driver bug, there shouldn't be any difference between the two (they both follow the v4l2 API). Please can you post the console output of: guvcview --verbosity=3 --format=yuyv also if possible unplug and then replug your camera, or if not, please run: sudo rmmod uvcvideo sudo modprobe uvcvideo Regards, Paulo 2014-09-29 13:29 GMT+01:00 Alberto Salvia Novella es204904...@gmail.com: ** Attachment added: dmesg.txt https://bugs.launchpad.net/ubuntu/+source/guvcview/+bug/1373221/+attachment/4219098/+files/dmesg.txt -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1373221 Title: guvcview crashed with SIGSEGV in get_ctrl_by_id() To manage notifications about this bug go to: https://bugs.launchpad.net/guvcview/+bug/1373221/+subscriptions -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1373221 Title: guvcview crashed with SIGSEGV in get_ctrl_by_id() To manage notifications about this bug go to: https://bugs.launchpad.net/guvcview/+bug/1373221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 1373221] Re: guvcview crashed with SIGSEGV in get_ctrl_by_id()
Hi, Hum, the frames are still coming empty, or at least with size set to 0. Are you using a 32 or 64 bit kernel ? I've run my tests on a 32 bit machine and I cannot test in 64 bit for several hours. I've add some more debug info to the logs, so if you could upgrade to the latest version on my testing ppa and run: guvcview --verbosity=3 --format=yuyv --disable_libv4l2 then please post the console output. This doesn't change anything but it prints some info on the mmap buffers ( size and position), I need to understand what's failing here.

Hi, just to make sure I've added a option to guvcview to disable calls trough libv4l2: guvcview --disable_libv4l2 with this all ioctls will go straight into the driver, bypassing libv4l2. you can upgrade from my testing ppa.
