Zencoder

An Elixir library for interacting with the Zencoder API.

Requires Elixir ~> 1.0.0

Installation

Install the Hex.pm package

Add zencoder and ibrowse to your mix.exs dependencies:

def deps do
  [
    {:zencoder, "~> 1.0.1"},
    {:ibrowse, github: "cmullaparthi/ibrowse", tag: "v4.1.0"},
  ]
end

Add :zencoder to your application dependencies:

def application do
  [applications: [:zencoder]]
end

API Key

To communicate with the Zencoder API you'll need to provide your API key, you can find your API key by logging into your Zencoder account and visiting https://app.zencoder.com/api

There are three ways to provide your API key to the Elixir library:

Set it from within your application
```
Zencoder.api_key "your-api-key"
```
Set it as the environment variable ZENCODER_API_KEY
```
ZENCODER_API_KEY=your-api-key iex -S mix
```
Every request takes a map as its final argument, you may provide your API key there
```
Zencoder.Job.progress(12345, %{api_key: "your-api-key"})
```

Base URL

By default the integration library will send all requests to version 2 of our API: "https://app.zencoder.com/api/v2". If, for whatever reason, you want to send requests to a different url you may configure your base URL in two ways:

Set it from within your application

Zencoder.base_url "https://app.zencoder.com/api/v1"

Set it as the environment variable ZENCODER_BASE_URL

ZENCODER_BASE_URL=https://app.zencoder.com/api/v1 iex -S mix

Timeout

We recommend wrapping your requests to Zencoder in a 30 second timeout. Zencoder usually responds in less than a second, so 30 seconds should give it plenty of time to respond. If the timeout is exceeded your request will return a %Zencoder.Error{} struct. If you wish to customize the length of the timeout you can do so by setting the timeout (in milliseconds) in three ways:

Setting it from within your application
```
Zencoder.timeout 60000
```
Set it as the environment variable ZENCODER_TIMEOUT
```
ZENCODER_TIMEOUT=60000 iex -S mix
```
Every request takes a map as its final argument, you may provide your custom timeout there
```
Zencoder.Job.progress(12345, %{timeout: 60000})
```

Responses

All API request functions will return either a %Zencoder.Response{} struct (which may or may not be successful) or a %Zencoder.Error{} struct if an exception occurred.

%Zencoder.Response{}

A Zencoder response has the following fields:

body: A Map containing the parsed body of the response, or an empty map if the response body could not be parsed
success?: true or false depending on if the request was successful
code: The HTTP status code of the response
headers: The response headers
raw_body: The raw string of the response body. (Likely JSON or an empty string)
errors: An List of errors, or an empty List. This is a shortcut for response.body[:errors]

%Zencoder.Error{}

A Zencoder error has the following fields:

stacktrace: The formatted exception
kind: The type of error
error: The exception

Stacktrace is the formatted exception (via Exception.format/2). The kind and error are provided if you wish to do your own formatting.

Pattern Matching

You can pattern match to determine how to handle the response:

case Zencoder.Job.create %{test: true, input: "http://s3.amazonaws.com/zencodertesting/test.mov"} do
  %Zencoder.Response{success?: true} = response ->
    # some happy path stuff here
  %Zencoder.Response{success?: false} = response ->
    # uh oh, maybe something is wrong with your request?
    # better check the docs at https://app.zencoder.com/docs
  %Zencoder.Error{} = response ->
    # timed out? Zencoder broken? Computers are hard! Perhaps some nice retry logic.
    # Check out our integration reliability guide:
    # https://app.zencoder.com/docs/guides/advanced-integration/stable-integration
end

Jobs

Create a new job.

# Basic job
Zencoder.Job.create(%{input: "http://s3.amazonaws.com/zencodertesting/test.mov"})

# More extensive job, see https://app.zencoder.com/docs/api/encoding for more encoding settings
Zencoder.Job.create(%{
  input: "s3://zencodertesting/test.mov",
  outputs: [
    %{
      label: "mp4 high",
      url: "s3://your-bucket/output-file-name.mp4",
      h264_profile: "high"
    },
    %{
      url: "s3://your-bucket/output-file-name.webm",
      label: "webm",
      format: "webm"
    },
    %{
      url: "s3://your-bucket/output-file-name.ogg",
      label: "ogg",
      format: "ogg"
    },
    %{
      url: "s3://your-bucket/output-file-name-mobile.mp4",
      label: "mp4 low",
      size: "640x480"
    }
  ]
})

Get details about a job.

Zencoder.Job.details(12345)

Get progress on a job.

Zencoder.Job.progress(12345)

List jobs. By default this returns the last 50 jobs, but this can be altered in an optional Map.

Zencoder.Job.list(%{page: 1, per_page: 5, state: "finished"})

Cancel a job

Zencoder.Job.cancel(12345)

Reports

Reports are great for getting usage data for your account. All default to 30 days from yesterday with no grouping, but this can be altered in the optional Map. These will return 422 Unprocessable Entity if the date format is incorrect or the range is greater than 2 months. Correct date format is YYYY-MM-DD.

# For a specific date range
