Motion - Support Question 2007x 05x 05x 184318

How to, on two equal bt878 cards, each one with 1 camera


To have better frames x second performance .

Works fine with 1 card, and 1 camera.

But, with a 2th card, and a 2th camera, the 2th motion instance, gets out of control.

What do you mean "out of control"?

What card are you talking about?

What is the configuration you use?

We need a better error report to be able to even consider resolving anything.

I reformatted your config text. Note how I put plain text inside <verbatim> and </verbatim> tags to get the text shown unformatted with all new lines. Also note that you can attach files to the topic.

You run with an old version of Motion. And the config file you use is some crippled version that someone that understands very little about customers put on a debian repository.

Please use the current version of Motion and use a full config file so you have control of everything.

On the DownloadFiles you have access to both sources and rpms and debs. Since you run debian you should be able to download and install the deb package that fits your distro. We have fixed quite many errors since 3.2.3 which was released 16 Aug 2005. People should really upgrade before submitting bugs reports and support questions.
