Google Cloud Node.js video transcoder

Use Google Cloud Storage, Pub/Sub and App Engine to transcode videos to many resolutions.

🔥 Setup

• Clone the app:

git clone https://github.com/diego3g/gcloud-node-video-transcoding.git

• Install all dependencies:

yarn
yarn lerna bootstrap

• Install GCloud CLI following https://cloud.google.com/sdk/docs/quickstarts?hl=pt-br
• Authenticate to Google Cloud:

gcloud auth login

• Setup a Google Cloud Project;
• Setup GOOGLE_APPLICATION_CREDENTIALS environment variable following https://cloud.google.com/docs/authentication/getting-started?hl=pt-br
• Create origin and destination bucket inside Google Cloud Storage;
• Create a topic inside Pub/Sub called jupiter;
• Setup Google Cloud Storage notification to new topic, so every file uploaded to bucket will publish a message to the queue:

gsutil notification create -t jupiter -f json -e OBJECT_FINALIZE gs://ORIGIN_BUCKET_NAME

Replace ORIGIN_BUCKET_NAME with your origin bucket name :)

• To see all the notifications:

gsutil notification list gs://ORIGIN_BUCET_NAME

• Update destination bucket name inside (https://github.com/diego3g/gcloud-node-video-transcoding/blob/master/packages/worker/src/services/transcode.ts#L26)

const destinationBucket = storage.bucket('DESTINATION_BUCKET_NAME');

• Run main application:

yarn dev:main

• Run worker application (in another terminal):

yarn dev:worker

• Upload .mp4 file to ORIGIN bucket and monitor logs via:

gcloud app logs tail -s default
gcloud app logs tail -s worker
