[FFmpeg-user] -flags2 +ivlc+non_linear_q issues

[Tim Nicholson]

Trying to generate some imx50 material using suggested parameters from
the web but when I add in the -flags2 options I get an odd error:-

[NULL @ 0x1823f20] Error setting option flags2 to value
+ivlc+non_linear_q.


Output #0, mxf_d10, to './BRD17568301-16x9-ffv1-d10.mxf':

I have tried using just '-flags2 +non_linear_q issues' and get a very
similar error:-

Undefined constant or missing '(' in 'non_linear_q'

Can anyone see something I have missed, or is this a regression?
