Command line screen recording with two monitors

Postby rohuezo » 02 Aug 2013 13:39

Hello,

I'm doing screen recording of automated test (middle of the night) using VLC command line. Here is the string I use to record:

Code: Select all

screen:// -I rc --rc-quiet --rc-host=127.0.0.1:81 -Vdummy --novideo --nommx --no3dn --nommxext --nosse :screen-fps=5.000000 :screen-mouse-image=File:///C:/temp/mouse.png --screen-left=0 --screen-top=0 --screen-width=1920 --screen-height=1080 :sout=#transcode{vcodec=h264,vb=384,fps=5,acodec=none}:file{dst=C:\\Temp\\out.mp4}
This command works great for recording the primary screen only. I have two identical monitors using the same resolution side by side which creates a desktop 3840x1080. I would like to record both monitors but I cannot make it happen. I have tried the following command but VLC will not record both monitors or the given dimensions:

Code: Select all

screen:// -I rc --rc-quiet --rc-host=127.0.0.1:81 -Vdummy --novideo --nommx --no3dn --nommxext --nosse :screen-fps=5.000000 :screen-mouse-image=File:///C:/temp/mouse.png --screen-left=0 --screen-top=0 --screen-width=3840 --screen-height=1080 :sout=#transcode{vcodec=h264,vb=384,fps=5,acodec=none}:file{dst=C:\\Temp\\out.mp4}
Here are the debug messages. You can see where I pass the 3840x1080

Code: Select all

qt4 debug: Adding option: live-caching=300 --screen-left=0 --screen-top=0 --screen-width=3840 --screen-height=1080
but VLC ignores that and enters the primary screen resolution 1920x1080:

Code: Select all

screen debug: screen width: 1920, height: 1080, depth: 32
The output video has the correct dimension 3840x1080 but the recorded screen is only 1920x1080.

So basically my question is: How can I record both screens using the VLC command line? Is there a screen-1:// or something similar? I couldn't find anything like that on the help. The only help I found on Screen-Input is here (in German):

Code: Select all

Bildschirm-Input --screen-fps=<Fließkommazahl> Bildwiederholrate Gewünschte Bildwiederholrate für die Aufnahme. --screen-top=<Ganzzahl [-2147483648 .. 2147483647]> Linke obere Ecke des Bildschirmteils Obere Koordinate der linken oberen Ecke des Bildschirmteils. --screen-left=<Ganzzahl [-2147483648 .. 2147483647]> Linke obere Ecke des Bildschirmteils Linke Koordinate der linken oberen Ecke des Bildschirmteils. --screen-width=<Ganzzahl [-2147483648 .. 2147483647]> Breite des Bildschirmteils Breite des Bildschirmteils --screen-height=<Ganzzahl [-2147483648 .. 2147483647]> Höhe des Bildschirmteils Höhe des Bildschirmteils --screen-follow-mouse, --no-screen-follow-mouse Maus verfolgen (standardmäßig aus) Verfolgt die Maus bei der Aufnahme eines Bildschirmteils. (standardmäßig aus) --screen-mouse-image=<Text> Bild für Mauszeiger Wenn angegeben, wird das Bild benutzt um, den Mauszeiger auf die Aufnahme zu zeichnen. --screen-fragment-size=<Ganzzahl [-2147483648 .. 2147483647]> Aufnahmefragmentgröße Aufnahme optimieren, indem der Bildschirm in Stücke mit vorgegebener Höhe unterteilt wird (16 könnte ein guter Wert sein und 0 bedeutet 'deaktiviert').
Which I'm using already most of these parameters.

I forgot to mention my system is Windows 7 64-Bit and VLC Version 2.0.7...

Sorry, it is probably not implemented.
