Ardour queries the video-server about the .avi (duration, fps etc). If
it can not not reach the server you get this message.

  - Is the video-server running?
 (these are the defaults, icsd -p <port> -P <listen-addr>)

  - Is the file readable by the video-server?
    or use
    http://localhost:1554/index/ to navigate to it.

The vseq.php script is for protoyping only. Maybe you're missing
'ffmpeg' or 'ffprobe' command-line utils ?
It has the same interface as icsd.
  http://localhost/vseq.php/status should say "ok[..]"
better use:

It should not even start like this. It requires a <docroot> to be given
on the commandline.  eg `./src/icsd /home/<user>/Videos/`

Just let ardour start it for you!

The first time you open a video [and it can't reach the server] it'll
ask you where the server is located (unless it is in $PATH).
The dialog will also suggest a docroot and set the preferences for you.

After starting the video-server (default port=1554) check

http://localhost:1554/index/  --to list the index of the docroot.
http://localhost:1554/status/ -- list open decoders & cached frames.

The ardour setting should be identical to what you've specified as
server-docroot when starting icsd.

The easiest is to leave it untouched and just let ardour start 'icsd'.
This way it'll use the same docroot for 'icsd' and save that in Ardour

When I wrote the videotimeline/README there was no setup-dialog. I'll
update the README soon.

It does not need to be started as root, but it does not matter.

That's perfect. The docroot is stripped from the full absolute path.

Thanks for giving it a go,
