nullsrc gives error

Michael Glenn Williams
Hi All,

Can we see anything wrong with this, running on MacOS Mojave as root in
bash shell.

ffmpeg -y -filter_complex "nullsrc=size=1152x540 [background];" output.mkv &

The error is:

[AVFilterGraph @ 0x7fb8834026c0] No such filter: ''

Error initializing complex filters.

Invalid argumen

try to remove the semicolon after [background]
