## How to build ffmpeg with NDI IO
I was able to find a VERY QUICK AND DIRTY way to use the media-autobuild suite to compile my own 64-bit static FFmpeg for Windows with the NDI library.

Download it and extract to a place on your computer, and keep note of the path. I put it in "D:\ndi\media-autobuild_suite-master", so for the sake of these instructions when you see "<autobuild>", you need to substitute whatever path you've put it in.

During the initial setup process, request to use the static build and add whatever else you'd like to have in your ffmpeg, then pause what you're doing when the on-screen prompts tell you the ffmpeg_options file has been written, then go into <autobuild>\build\ffmpeg_options.txt and add somewhere a line with

Code:
--enable-libndi_newtek

    ffmpeg 4.4 with NDI

This patch adds libndi_newtek to last ffmpeg version, and fix timecode related issues that produces wrong PTS/DTS timestamps that seems to happen with newer NDI SDKs.
changes


Updated libndi methods by newer versions (v2/v3)
Calculating PTS/DTS from timestamp instead of timecode, that is optionally sent by the sender.
