Answer

I changed your Feature request to a support request.

You have given FAR to little information for anyone to help you.

We need to know

Motion version

Which camera?

What is your motion.conf?

Any other errors?

Does your camera work in other programs?

Motion: 3.1.19 ffmpeg: 0.4.9-pre1 and 0.4.9-0 Libraries: ffmpeg OS: Fedora Core 3 2.6.11-20_FC3

I had the same problem when I upgraded ffmpeg 0.4.9-pre1 through yum and FreshRPMS.net. I'm using an older Phillips webcam (PCVC 740K) and the pwc drivers. From what I've been able to find on the web, the images produced by this set up have a palette of YUV420p, which from the error message appears to not be supported by the ffmpeg verison I got from FreshRPMs.net. I grabbed sources for ffmpeg 0.4.9-pre1 and recompiled, then linked motion to this version of ffmpeg, now everything works great.

Hopefully this will help anyone who like me has this problem and runs across this support request.

I have the same problem. Here are some details:

Exact Error:

# motion -n
Processing thread 0 - config file motion.conf
Thread 0 started
motion-httpd/3.2.1 running, accepting connections
motion-httpd: waiting for data on port TCP 8080
[mpeg4 @ 0x3fbf10]only YUV420 is supported
avcodec_open - could not open codec: Success
Segmentation fault

NOTE: I can view the live images by going to localhost:8081 and it is fine until the camera sees motion, once the camera sees motion it crashes with the above error.

I also tried msmpeg4, same error, just with msmpeg4v2 of course.

Did you try reinstalling a newer or older version of ffmpeg?

You probably have a badly working version. Ffmpeg is almost never releasing anything properly. It is always semi-tested shit CVS releases that they do. The ffmpeg have no release discipline what so ever unfortunately.

You can also download a source RPM and rebuild it. It fixed a problem for me. The RPMs from Dag and others often only works with specific other RPMs. A rebuild of the RPM from source RPM can fix dependencies.

-- KennethLavrsen - 18 May 2005

Ok, problem solved. The CVS version of ffmpeg is flawed. I downloaded the stable 0.4.9-pre1 version compiled and installed it. I then had to recompile and install motion but it all works now. Thanks,

Nick
