Hello.
I have 2 PCs.
1-st with video capture device
2-nd control system

I want to start vlc from 2-nd PC at 1-st PC with ssh command and vlc starts, but then exits.

Code: Select all


ssh video@10.0.0.1  "/home/video/go"
VLC media player 0.8.6 Janus

"/home/video/go" - is a script with command line like
/usr/bin/vlc -I dummy --daemon v4l:// ...
BUT(!) When i run manually by

Code: Select all

ssh video@10.0.0.1
video@10.0.0.1$/home/video/go
VLC media player 0.8.6 Janus

vlc starts and all works fine.
What is wrong?

P.S. screen is bad idea, couse i have to execute commands in scipts running from cron

I would guess that in the first case, when you start ssh with the go-command, it will be started as the shell that is dying as soon as the go-script finishes.

A simple WA could be to start vlc with
vlc -I... &
to fork it?

It isprobably a timing issue, that the go script exits before vlc is completely initialized and can take it's own control.

Regards,
Dominique

no.
vlc needs tty allocation.
all fixed.
Thanks.

vvvua,

for the records: can you tell the solution here, so in case somebody else comes accross the problem, he has chances not only to find that somebody else had the problem, but also a solution?

That's usually what I miss in Forums

ok.
solution is:
1. setup ~/.ssh/known_hosts for ssh2 authentification without password promt
2. Now you can execute vlc or script with vlc inside with

Code: Select all

ssh -t user@remote_mashine "/path/to/vlc/vlc -I dummy --daemon ... ... ..."
