I don't think the 31k on the heap are really an issue, but OTOH having a
dynamic allocation in the init may easier the use of the opaque arg:
ffmpeg -map_channel will may use of this filter; while we can certainly
build a string easily and init the filter with it, using the opaque
parameter might slightly simplifies things.

I don't have any strong opinion on that matter though. Patch looks ok (if
tested), and the dynamic allocation can be done later if necessary.
