I would *definitely* be willing to sponsor some work to make OPUS sample rate, complexity, vbr, etc more dynamic with channel variables or even ESL commands ;).

Look at ./conf/vanilla/autoload_configs/opus.conf.xml, Currently it only has complexity, and use_vbr, adding additional options to the config and parser should be simple, work a patch up, file a JIRA and you’ll have started down the road of contributing back to the project.

This is the patch where the VBR/Complexity options and the config file were added.
