This filter is useful for the creation of output windows such as the one utilized in vrecord.

The following example uses the 'testsrc' virtual input combined with the split filter to generate the multiple inputs. +
,
separates this from the next part of the filter chain.
+ :
is a necessary divider between the number of inputs, and the orientation of outputs portion of the xstack command.0_0
corresponds to input [a]
. Inputs must be separated with a |
. The two numbers represent columns and rows, with counting starting at zero rather than one. In this example, 0_0
means that input [a]
is placed at the first row of the first column in the output. 0_h0
places the next input in the first column, at a row corresponding with the height of the first input. 0_h0+h1
places the final input in the first column, at a row corresponding with the height of the first input plus the height of the second input. This has the effect of creating a vertical stack of the three inputs. This could be made a horizontal stack by changing this portion of the command to layout=0_0|w0_0|w0+w1_0
.
