I have no trouble showing it using the exact same version of vlc (on
Ubuntu 15.10). I guess it is a problem with codecs or something.

I've found the documentation for vlc usage very poor; this is something
I pulled from the 'net and seemed to work, before motion (mr dave's
fork) supported rtsp. I don't need to worry now I'm confident the
timelapse videos are correct. I was considering using it as a non-motion
based timelapse solution, and was curious to whether the command was
documented somewhere.

Hello
Is it possible for motion to record a continuous video, ie not
timelapse, just a raw stream? I appreciate vlc or something could do
this but it's another thing to configure - and as motion has got the
stream, it would be nice if it could write it to disc.

I dont quite understand
u mean after the "motion detection" it will continue save the picture and
eventually encode it (after you kill the process) ?
if that whats you mean,you may start looking at event_gap config:

I'm asking if motion can record a raw video as well as the other
options, such as timelapse, record motion on detection, snapshots, etc.
Given disc space is practically free, a range of video output options
seems sensible.
