Command line screen recording with two monitors
Posted: 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:
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:
Here are the debug messages. You can see where I pass the 3840x1080
but VLC ignores that and enters the primary screen resolution 1920x1080:
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):
Which I'm using already most of these parameters.
