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.

About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

• Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
• Simple - This solution has few dependencies, readily available packages and minimal configuration.
• Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43
