- Manual key frame passing
- Progress reporting
- Test tree shaking
- Throw if edit list detected
- Audio codec string regex validation
- Add the new audio codecs to muxers
- Mov muxer!!! Only mov can hold PCM audio, MP4 cannot
- Metadata methods for computing average fps and bitrate
- close method on Output to cancel it (and dispose the encoders). Perhaps abort is a better title
- lower default key frame interval (3 secs is better I think?) and make it outside-configurable
