[Bug 1041432] Re: cheese and camorama freeze system when recording video
this bug can be fixed by this patch From 4cd9255f0a8a9e15d81561f00f02d275b5095f70 Mon Sep 17 00:00:00 2001 From: Oleksij Rempel (Alexey Fisher) bug-tr...@fisher-privat.net Date: Thu, 01 Mar 2012 13:15:29 + Subject: v4l2src: fix v4l2_munmap() for compressed formats Make sure we always call munmap() with the same size we called mmap() with before. Current v4l2src uses the same structure for VIDIOC_QUERYBUF, VIDIOC_QBUF and v4l2_munmap calls. The problem is that the video buffer size (length) may vary for compressed or emulated bufs. VIDIOC_QBUF will change it if we pass the pointer of a v4l2_buffer. This is why we should avoid using same variable for mmap and video buffers. https://bugzilla.gnome.org/show_bug.cgi?id=671126 ** Bug watch added: GNOME Bug Tracker #671126 https://bugzilla.gnome.org/show_bug.cgi?id=671126 ** Patch added: 0001-fix-v4l2_munmap.patch https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/1041432/+attachment/3508463/+files/0001-fix-v4l2_munmap.patch ** Description changed: - Quantal 3.5.0-11 becomes totally unresponsive when starting a video from - the built in webcam.

Redhat has a similar bug that video device is busy when doing video recording. - https://bugzilla.gnome.org/show_bug.cgi?id=670257 Gstreamer bugs: - https://bugzilla.gnome.org/show_bug.cgi?id=670257 Explain for the patch: When recording video, Cheese uses gsteamer to set caps, meanwhile cmaera device re-init while caps settings. because the buffer is not freed and kernel complain that camera device is busy, so cheese hangs. ** Bug watch added: GNOME Bug Tracker #670257 https://bugzilla.gnome.org/show_bug.cgi?id=670257 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1041432 Title: cheese and camorama freeze system when recording video To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1041432/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

gucview suits my hardware better than cheese. If I have time, I'll get to the cheese issue. I always have the latest kernel and proposed updates.
