Hi,

I'm capturing selenium tests as they execute, and saving video records of their behavior for future analysis. That requires starting and stopping VLC via a script.

I have a batch file on win7 that starts a screen capture just fine:

Code: Select all

del C:\Users\tsmith\capture2.avi
call "C:\VideoLAN\VLC\vlc.exe" ^
     screen:// --one-instance ^
     -I dummy --dummy-quiet ^
     --screen-follow-mouse ^
     --no-video :screen-fps=5 :screen-caching=300 ^
     --sout "#transcode{vcodec=h264,vb=400,fps=5,scale=1,width=1024,height=768,acodec=none}:duplicate{dst=std{access=file,mux=avi,dst='C:\\Users\\tsmith\\capture2.avi}}"

Stopping the capture is tougher. If I use 'pskill' or some other process killer, the output file is corrupted. So, there needs to be a way to gently stop VLC.

The question is: How do you do tell the vlc process (started by the batch file) to quit recording?

Thanks,

use rc or http interface.

use rc or http interface.

Thanks. I was looking at that approach. Can you point me to an example? It isn't clear how to stop a vlc process via the http interface.

TIA,

Hi,

For the record, here is the solution. There are 2 scripts. One to start vlc screen capture, and another to stop it.

Starting script contents:

Code: Select all

del C:\Users\tsmith\capture2.avi
call "C:\VideoLAN\VLC\vlc.exe" ^
     screen:// --one-instance ^
     -I dummy --dummy-quiet ^
     --extraintf rc ^
     --rc-host localhost:8088 ^
     --rc-quiet ^
     --screen-follow-mouse ^
     --no-video :screen-fps=5 :screen-caching=300 ^
     --sout "#transcode{vcodec=h264,vb=400,fps=5,scale=1,width=1024,height=768,acodec=none}:duplicate{dst=std{access=file,mux=avi,dst='C:\\Users\\tsmith\\capture2.a
vi'}}"

Stopping script contents:

Code: Select all

echo quit | "C:\Program Files (x86)\Nmap\ncat.exe" localhost 8088

That's it. Thanks for the suggestions.
