New fixes in nginx-rtmp:
- Aggregated RTMP message support. These are plain FLVs inside RTMP stream. FMS publishes that kind of data in certain cases.
- Fixed auto-generated tcUrl in relay module in case full RTMP url is specified in pull directive. The tcUrl is sometimes verified by server.
- Implemented skipping empty H264/AAC headers.
- Fixed RTMP acknowledge messages. This bug could result in stream disconnect when publishing from FMS.
All the fixes are implemented in aggregate branch.
