Description

When I attempt to create the following filter:

"zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=mobius:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p,scale=1920:1080"

the filter throws an exception when attempting to start:

org.bytedeco.javacv.FrameFilter$Exception: avfilter_graph_parse_ptr() error -22

The filter in question works fine from ffmpeg command line, but I'm using this filter with frame grabber. Any suggestions?
