piping out the bmdtool output to ffmpeg.
There is lot of things need to be done if you want to use bmd logic of 
ffmpeg.

Step1) grab the bmdtools from my git repository.
https://github.com/anshul1912/bmdtools.git

Step2) grab the FFmpeg from my fork repository
https://github.com/anshul1912/FFmpeg.git
Note: This ffmpeg fork is used as my backup of ffmpeg, so commit message
are not very well aligned and there are lots of garbage in this repo.

Step 3) pipe the nut output of bmdtool to ffmpeg
Note: If you do have bmd device, then also take pains by asking your 
broadcaster
on which line they are giving scte data, because there is no predefined 
line for this.

I dont own any bmd device, so I cant give ssh or access to my pc with 
device.

I have tested it for weeks, I don't see any issue with my scte-35 logic yet.
