Hello,
I'm just testing the new feedback filter with this command line:
ffmpeg -i test.jpg -vf
"[in][fb_in]feedback=x=2000:y=1000:w=2000:h=2000[out][fb_out];[fb_out]gblur=50[fb_in]"
-map "[out]" -y out.jpg
I get this error message:
Output with label 'out' does not exist in any defined filter graph, or
was already used elsewhere.
When I remove -map "[out]" then it works. But I don't understand why I
can't map [out] to the output. The console output is below.
Michael
