I know it may be possible duplicate of this, but...
I'm trying to use answer given there like this:
ffmpeg.exe -i http://xxx:8080/video -i http://yyy:8080/video -filter_complex "[0:v] scale=iw/2:ih/2, pad=2*iw:ih [left]; [1:v] scale=iw/3:ih/3, fade=out:300:30:alpha=1[right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k Output.mp4
But getting an error:
Output pad "default" with type video of the filter instance "Parsed_overlay_4" of overlay not connected to any destination
What am I doing wrong?
