Amazon VOD Preset Converter

Python script that allows users to convert Amazon Elastic Transcoder presets to AWS Elemental MediaConvert presets.

Setting up Environment

You will need to install Python 2.7 onto the machine where you are running the script

Verify Python is Installed

Python may be installed by default on your machine, or you may have used it in a previous workflow. To verify if Python is installed and what version you have, run the following command:

python –version

Please make sure that the Python version is a variation of 2.7.x.

Installing AWS CLI

Use the following URL for the latest “Installing the AWS Command Line Interface”

http://docs.aws.amazon.com/cli/latest/userguide/installing.html

$ aws configure
AWS Access Key ID [****************1234]:
AWS Secret Access Key [****************abc]:
Default region name [us-east-1]:
Default output format [json]: json

Pre-Work

Make sure the ets_mediaconvert_preset_v2.py is located on your machine, and then make ets_medaconvert_preset_v2.py executable using the following chmod command:

chmod +x ets_mediaconvert_preset_v2.py

Script Parameters

Running the script will provide the following help menu. You can also use the ‘-h’ parameter to show the help menu.

$ python ets_mediaconvert_preset_v2.py
usage: ets_mediaconvert_preset_v2.py [-h] [-r REGION] [-p ETSID] [-v] [-i] [-c OUTPUTTYPE] [-f]
ETS to AWS Elemental MediaConvert preset converter

optional arguments:
-h, --help                               show this help message and exit
-r REGION, --aws-region REGION           Valid ETS AWS Region to connect to
-p ETSID, --preset-id                    ETSID ETS Preset ID
-v, --verbose                            Verbose debug messages
-i, --interactive                        Interactive Mode for user
-c OUTPUTTYPE, --output-type OUTPUTTYPE  Output group type for preset to move to 
                                         ex: file, apple, dash, smooth
-f, --save                               Save presets to file

The following parameters are required if you are not using interactive mode.

-r, -p, -c

If you use interactive mode (‘-i’) then all other parameters fed in will be ignored and you will need to follow the prompts.

If you want verbose logging enabled, use the ‘-v’ parameter. When verbose logging is enabled, you will see the JSON output for each step of the conversion process.

For the ETS Preset ID (-p, --preset-id), you can find a list of your presets by logging into the AWS Console, selecting Amazon Elastic Transcoder from the services menu, and clicking on Presets in the left hand navigation.

Error Handling

The script handles improper configurations and warns the user when this happens.

Error examples:

1. Containers and Codecs not currently supported by AWS Elemental MediaConvert
2. Improper output group configurations, such as DASH with Transport Stream codecs

Saving Preset to File

When using the -f (or --save) flag this will save two files. One contains the video and audio parameters the other contains a Thumbnail preset. When this flag is excluded, the output of the script will just print on the terminal screen.
