# ExoPlayer cast receiver #
An HTML/JavaScript app which runs within a Google cast device and can be loaded
and controller by an Android app which uses the ExoPlayer cast extension
(https://github.com/google/ExoPlayer/tree/release-v2/extensions/cast).
# Build the app #
You can build and deploy the app to your web server and register the url as your
cast receiver app (see: https://developers.google.com/cast/docs/registration).
Building the app compiles JavaScript and CSS files. Dead JavaScript code of the
app itself and their dependencies (like ShakaPlayer) is removed and the
remaining code is minimized.
## Prerequisites ##
1. Install the most recent bazel release (https://bazel.build/) which is at
least 0.22.0.
From within the root of the exo_receiver_app project do the following steps:
2. Clone shaka from GitHub into the directory external-js/shaka-player:
```
# git clone https://github.com/google/shaka-player.git \
external-js/shaka-player
```
## 1. Customize html page and css (optional) ##
(Optional) Edit index.html. **Make sure you do not change the id of the video
element**.
(Optional) Customize main.css.
## 2. Build javascript and css files ##
```
# bazel build ...
```
## 3. Assemble the receiver app ##
```
# WEB_DEPLOY_DIR=www
# mkdir ${WEB_DEPLOY_DIR}
# cp bazel-bin/exo_receiver_app.js ${WEB_DEPLOY_DIR}
# cp bazel-bin/exo_receiver_styles_bin.css ${WEB_DEPLOY_DIR}
# cp html/index.html ${WEB_DEPLOY_DIR}
```
Deploy the content of ${WEB_DEPLOY_DIR} to your web server.
## 4. Assemble the debug app (optional) ##
Debugging the player in a cast device is a little bit cumbersome compared to
debugging in a desktop browser. For this reason there is a debug app which
contains the player parts which are not depending on the cast library in a
traditional HTML app which can be run in a desktop browser.
```
# WEB_DEPLOY_DIR=www
# mkdir ${WEB_DEPLOY_DIR}
# cp bazel-bin/debug_app.js ${WEB_DEPLOY_DIR}
# cp bazel-bin/debug_styles_bin.css ${WEB_DEPLOY_DIR}
# cp html/player.html ${WEB_DEPLOY_DIR}
```
Deploy the content of ${WEB_DEPLOY_DIR} to your web server.
# Unit test
Unit tests can be run by the command
```
# bazel test ...
```
