## Install the Manzanita applications

##### Create work dir
```
mkdir ~/Downlaods/manzanita
cd ~/Downlaods/manzanita
```

##### MP2TSME
```
wget --user=<USER> --password=<PASSWORD> www.manzanitasystems.com/manzuser/dwbavr.zip
```
##### MP4Mux
```
wget --user=<USER> --password=<PASSWORD> www.manzanitasystems.com/manzuser/etzqgz.zip
```
##### Unzip with credentials
```
unzip -P <PASSWORD> -o dwbavr.zip
unzip -P <PASSWORD> -o etzqgz.zip
```

##### This may fail if the version changes
```
tar -xvzf mp2tsme-8.1.78.x86_64.tgz
tar -xvzf mp4mux-3.0.9.x86_64.tgz
```
##### Create sys link
```
ln -s manzanita/mp4mux/mp4mux /usr/bin/mp4mux
ln -s manzanita/mp2tsme/mp2tsme /usr/bin/mp2tsme
```
##### Configure license
###### Only needs to happen once
> Fully automated way to configure the license
```
$ (echo 3; echo <manzanitaLicenseServer>; echo y; echo <manzanitaCustomerKey> ) | mp4mux -liccfg
$ (echo 3; echo <manzanitaLicenseServer>; echo y; echo <manzanitaCustomerKey> ) | mp2tsme -liccfg
```


## Running the application

Using Manzanita embedding(608/708) captions is a 4 step process.

 1. Demux the mp4's elementary streams using MP4Mux.
 2. Embed the scc sidecar file into the h.264 video elementary stream using MP2TSME.
 3. Create an MP4Mux config file.
 4. Mux the new video elementary stream that has captions with the audio stream using MP4Mux.

## Steps

##### Create Work Dir
```
$ mkdir ~/Desktop/manzanita
$ cd ~/Desktop/manzanita
```

##### Download required files
```
$ wget <location of an mp4> -O source.mp4
$ wget <location of an scc caption file> -O caption.scc
```

##### Demux the source mp4
```
$ mp4mux -dd source.mp4 1 source.h264 2 source.aac
```

##### Embed the the caption into elementary stream to produce a new file called source_ecc.h264
```
$ mp2tsme -c source.h264 source_ecc.h264 caption.scc
```

##### Create the MP4Mux config file
```
$ echo 'mp4mux-config 2,0
       output: {/Users/<USER>/Desktop/manzanita/source_ecc.mp4}
       delivery-target: Disabled
       movie-fragments: Disabled
       fragment-time: 2.0
       major-brand: mp42
       free-box: Before-mdat
       tracks [
         video [
           filename: {/Users/<USER>/Desktop/manzanita/source_ecc.h264}
           track-id: 1
         ]
         audio [
           filename: {/Users/<USER>/Desktop/manzanita/source.acc}
           track-id: 2
         ]
       ]
       /mp4mux-config
' > config.cfg
```
###### Run MP4Mux to generate the new mp4 with embedded Closed Captions
```
$ mp4mux config.cfg
```
