Interesting. The video has the same sort of corruption when I set the
motion configuration parameters via the static configuration files and
start running it. This didn't used to be the case, the videos used to
record properly. I have multiple cameras and recording with any of them
triggers this issue. Also worth noting is that I have two different types
of IP cameras and since the issue affects both I suspect it has to do with
motion rather than the cameras themselves.
I updated my configuration to have just one camera and the issue persists.
I've attached the motion log and an example file. If you look at the time
on the upper right of the video you will see it stop after ~2 seconds,
whereas the video runtime is 6 seconds.
I could try recording jpegs instead and make videos, but I would really
only want to do that as a last resort. Hopefully I can figure out this
issue and get the videos working directly. Especially since they were
working before.
Thanks for your help everyone.
Best,
Jon
