sendcmd and overlay

Michael Koch
I want to use sendcmd to set the x,y coordinates of the overlay filter.
If I write sendcmd before overlay, I get this error message:
Too many inputs specified for the "sendcmd" filter.
But the two inputs are required for the overlay filter. How can this
problem be solved?

Console output is below.

Michael

I don't understand what you mean. At which place shall I put it?

One of inputs before overlay filter:

[a]sendcmd=...[a];[a][b]overlay....

ok, I did try this command, but now I got another error message. It
seems that the overlay filter doesn't receive the x value.

c:\ffmpeg\ffmpeg -i main.mov -i lp.mp4 -filter_complex
"[1]scale=100:100,sendcmd=f=test.cmd[2];[0][2]overlay=x='':y=''" -q:v 2
-t 4 -y out.mp4


This is my test.cmd file:

0.0-1.0  overlay x 'lerp(1000,2000,t)',
          overlay y 'lerp(800,800,t)';

1.0-2.0  overlay x 'lerp(2000,1500,t-1)',
          overlay y 'lerp(800,400,t-1)';

2.0-8.0  overlay x 'lerp(1500,1500,t-2)',
          overlay y 'lerp(400,500,t-2)';


Console output:

F:\Test>c:\ffmpeg\ffmpeg -i main.mov -i lp.mp4 -filter_complex "[1

Should be added to sendcmd documentation:

-- An example which shows where to insert the sendcmd filter, if the
target filter has more than one input.
-- All arguments of filters must be initialized with valid values, even
if they are never used because sendcmd overwrites them.

sorry, I never figured out how git works. Too complicated for me.

Another idea: Could sendcmd be modified so that it can be inserted at
any place in the filter chain, regardless of the number of inputs?

Not needed. sendcmd isn't tied to any specific filter, since it can be
used to send commands to any or all filters in the graph at once.

I'll add an example showing sendcmd usage for multi-input filters.
