Comment:

 When you assign an option constant you should not rely on expressions such
 as CONST op CONST.

 Anyway the volume syntax was extended in:

     lavfi/volume: support volume expression and per-frame expression
 evaluation

     The eval mode allows to evaluate the expression per-frame or just at

     In particular, address ticket #3234.
 }}}
