[FFmpeg-user] concatenation problem with XDCAM mxf files

[James Heliker]

I'm trying to concatenate to XDCAM files (successfully generated from 
other FFmpeg commands) - and receiving an odd error: "[AVFilterGraph @ 
028a8280] No such filter: ''
Error configuring filters." Any help would be much appreciated!!

C:\ffmpeg.exe -i slate_output.mxf -i black_output.mxf -filter_complex 
"[0:0] [1:0]" concat=n=2:v=1 [v]" -map "[v]" concattest.mxf
