[FFmpeg-devel] Patches to add libomt OpenMediaTransport support to FFmpeg

[FFmpeg-devel] Patches to add libomt OpenMediaTransport support to FFmpeg

[ffmpeg]

Hi Folks

We are part of the group creating a new open source and free to use professional IP Video protocol called OMT (open media transport)
It's similar to NDI in many ways, but completely open source and royalty free.

The protocol will officially launch on August 18th.
You can read about it here:
https://openmediatransport.org/
and 
https://github.com/openmediatransport/
The github is not public yet, but will be after the launch

The video codec used in OMT is actually the same as the vmix codec which is already implemented in decoder-only form in FFMPEG.

We have already completed implementation of this protocol into FFMPEG 7 and I enclose patches to add this to the current FFmpeg origin/master.

To build this also requires the pre-built omt libraries which are available at   
https://github.com/openmediatransport/libomtnet/releases
also, available from:    
https://www.sienna-tv.com/omt/OMTlibs.zip

Please let me know if you have any questions

Best Regards
Mark Gilbert

It's a bit premature to be sending this then, no? We can't review
or make a value judgement.

I don't see any; perhaps you missed including them?

The community will wait on source code, I suspect.
