Streaming twitch.tv on your Raspberry Pi 2

The following will explain the steps necessary to stream twitch.tv (as well as other media sites like YouTube) on the Raspbian (wheezy) distribution for the Raspberry Pi 2. While you should be able to accomplish the following instructions with Python 2.6.x, I recommend using 2.7.10+.

Low-Latency Live Streaming for your Desktop using ffmpeg and netcat:

Preamble:

In this post I will explore how to stream a video and audio capture from one computer to another using ffmpeg and netcat, with a latency below 100ms, which is good enough for presentations and general purpose remote display tasks on a local network.

The problem:

Streaming low-latency live content is quite hard, because most software-based video codecs are designed to achieve the best compression and not best latency. This makes sense, because most movies are encoded once and decoded often, so it is a good trade-off to use more time for the encoding than the decoding.

FFmpeg and libav's playbook: Advanced encoding options with hardware-based acceleration, NVIDIA's NVENC and Intel's VAAPI-based encoder.

Hello guys,

Continuing from this guide to building ffmpeg and libav with NVENC and VAAPI enabled, this snippet will cover advanced options that you can use with ffmpeg and libav on both NVENC and VAAPI hardware-based encoders.

For ffmpeg:

ogmkp

apt-get install mysql-server
sed -i "s/^\(bind-address.*=\).*/\1 0.0.0.0/" /etc/mysql/mariadb.conf.d/50-server.cnf
service mysql restart
mysql -e "create database nextcloud;"
mysql -e "CREATE USER nextcloud@'%' IDENTIFIED BY 'mypassword';"
mysql -e "GRANT ALL PRIVILEGES ON nextcloud.* to 'nextcloud'@'%';"

ogmkp

#This script will compile and install a static ffmpeg build with support for nvenc un ubuntu.
#See the prefix path and compile options if edits are needed to suit your needs.
