Dagger step 1: Add android-apt, dagger 2, dagger2-compiler, and javax annotation to the build.gradle files.
Note that they're not all "compile" dependencies.

Step 2: Add our module. Our ApplicationModule will be able to inject the ApplicationContext to classes that need it.

Step 3: Add our Component.Dagger 2 generates code for each Component you create,
using the file name Dagger(NameOfComponent).
Example: DaggerApplicationComponent.
Components can have multiple modules, in our case we have one.

Compile FFmpeg on Ubuntu

This basic guide supports Ubuntu Xenial Xerus 16.04 and will enable several external encoding and decoding libraries: libfaac (AAC encoder), libfdk-aac (AAC encoder), libmp3lame (MP3 encoder), libopencore-amr (AMR encoder/decoder), librtmp (for additional RTMP protocols), libtheora (Theora encoder), libvorbis (Vorbis encoder), libvpx (VP8 encoder/decoder), and libx264 (H.264 encoder). These are optional and may be omitted if desired. This guide will also install many filters (see the filter list in the [Filtering Guide][1].

Note: Copy and paste the whole code box for each step.
