> should I also focus more on getting things done instead of trying to find the best solution?

This question can only be answered in the context of the project's life cycle. Is it in the early stages? Are there many downstream users relying on its stability? How clearly is the distinction between internals and interface communicated to downstream users? How technical are the end users?

> the fact that ffmpeg has more features and its devs fix bugs and security issues more quickly seem to suggest that ffmpeg is more maintainable

Or it could just be that ffmpeg has people who are willing to dedicate a much larger amount of time to their maintainership duties. Often differences like this have much more to do with nontechnical causes like corporate support.
