[Bug 714439] New: camsource doesn't work anymore.
https://bugzilla.novell.com/show_bug.cgi?id=714439 https://bugzilla.novell.com/show_bug.cgi?id=714439#c0 Summary: camsource doesn't work anymore. Classification: openSUSE Product: openSUSE 12.1 Version: Milestone 3 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: matwey.kornilov@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux i686; rv:5.0) Gecko/20100101 Firefox/5.0 As far as I understand Video4Linux1 compatibility was removed from the kernel (commit id 08af245de0cf6ab5f4ed008ee2bb99273774fce0). This means that camsource (which uses v4l 1 api) can't operate with /dev/video? anymore.This is supported by 'ioctl "get video cap" failed: Invalid argument' message when using specific v4l ioctl command.. There is no known patch that fix camsource to use v4l2. Moreover camsource seems be not maintained anymore (last activity on its site was at 2003). However, camsource can still grab images from other sources (i.e. input_xwd) and one can't say that it is fully useless. Unfortunately, the simplest solution is to remove this package from the distribution. But It seems to me that the patch can be easily prepared. Reproducible: Always Steps to Reproduce: 1. 2. 3.

It looks for the process to kill by name, but fails to find it, because the name it's looking for (camsource) is hardwired in, but the name of the real executable has been changed to "camsource.bin". A more complete fix would change the hardwired name to "camsource.bin" at main.c line 228. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This fix almost works, except that "camsource -k" no longer kills the running camsource process. It looks for the process to kill by name, but fails to find it, because the name it's looking for (camsource) is hardwired in, but the name of the real executable has been changed to "camsource.bin". A more complete fix would change the hardwired name to "camsource.bin" at main.c line 228.
That is why there is camsource-rename.patch in the original submission and with it it worked for me. (In reply to comment #5)
The most complete fix would link libv4l1 at compile-time (with some fixes in input_v4l.c), there is no need in wrapper at all.
Feel free to fix it better and send your fix via OBS ;-) Only reason I touched it was that nobody cared enough to implement even the easy workaround... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Tried again. It is easily misunderstanding, my first attempt had been 3 hours before your and was declined as "superseded". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
