We introduce new feature: synchronization of feeds by timecode.
Common info
Some SRT encoders like new JVC-cams , Haivision-encoder and software encoder LarixBroadcaster (iPhone/Android) can do this:
synchronize internal clock by time-server (usually by NTP protocol).
It means all encoders have one clock:if one camera has time 11:59:59 then other cameras have same time.
send this time inside encoded feed (SEI metainfo)
There are exists few ways for send time-info inside feed. Current version SRTMiniServer supports popular 'timecode inside SEI' method only. Other methods will be supported later.
How it works
start streams from JVC cams (or other SRT encoders with Timecode support)
run TimeCode Sync addon
add lines to addon
press "Auto balance"
now you can use NDI source called "TimeCodeSync-*" in vMix, Tricaster etc
For example: we stream one monitor with real timecode (it shows mins,seconds and frames).
before: result is different
after: result is very close. 1-frame diff
What's about accuracy ?
In real test we have 1-3 frames accuracy for 60 fps feeds. It's enough in many cases.
Examples
We tested addon on feed from Haivision Makito X4 encoder and JVC
