BUG: Motion 3.2.3 crashes with Seg Fault at first detection

Motion compiled from sources 3.2.3 along with ffmpeg-devel-0.4.9-0.lvn.0.18.20050801.3 & ffmpeg-0.4.9-0.lvn.0.18.20050801.3 causes it to Seg Fault when motion is first detected.

I am using an X10 USB camera with the spca5xx driver.

Another setup using this camera & USB capture device along with compiled motion 3.1.19 using rpms ffmpeg-devel-0.4.8-3.1.fc2.dag; ffmpeg-0.4.8-3.1.fc2.fr on a FC2 2.6.5-1.358 works fine!

I am trying to run motion on an Linux version 2.6.12-1.1372_FC3 (bhcompile@tweetyPLEASENOSPAM.build.redhat.com) (gcc version 3.4.3 20050227 (Red Hat 3.4.3-22)) #1 Fri Jul 15 00:59:10 EDT 2005

I compiled motion from source but it crashes as soon as it detects motion. Could you help please? Here is a backtrace:

I have the following RPMs installed:

Thanks JMB

Follow up

Did you install Motion from RPM.

Someone just reported that my download link pointed to the old version which indeed fails with the newer ffmpeg versions.

See SupportQuestion2005x12x02x153609

Link is correct now. If you compiled from source Motion should have built itself correctly.

Note. You do not need to put %BR% after each line. To show errors/logs etc just put the text inside <VERBATIM> and </VERBATIM> tages. Like I just did.

Fix record

Assume the wrong link at Download was the issue.

Bug closed.
