- Related issues: #1119
- Requested reviewers:
Reason why this change is needed
The decoder to split rendering output crashes when decoding JBM bitstream. From a quick inspection of the code, it seems that this feature is not implemented at all.

As a stopgap solution, return an error for unsupported configs to prevent uncontrolled crashes.
Affected operating points
Decoder in VoIP mode with split rendering output configuration. Bit-exactness not applicable because processing always fails.
