- Added support for new "NowMs" field that holds up to where no new packets are guaranteed to show up, in order to lower latency.
- Added support for JSON tracks over all TS-based protocols (input and output)
- Added support for AMF metadata conversion to JSON (RTMP/FLV input)
- Fixed MP4 input subtitle tracks
- Generalized websocket-based outputs to all support the same commands and run the same core logic
- Added new "JSONLine" protocol that allows for generic direct line-by-line ingest of subtitles and/or JSON metadata tracks over a TCP socket or console standard input.
