Triggering renders from Ruby

packages/docs/docs/lambda/ruby.mdx

4.0.4652.6 KB
Original Source

available from v4.0.232

To trigger a Lambda render using Ruby, install the remotion_lambda gem.
The version should be the same version of the @remotion/lambda NPM package version that you used to deploy your function.

Notes

  • This module is experimental and might have breaking changes in minor versions. Check on this page for up-to-date examples.
  • The implemented methods are renderMediaOnLambda(), renderStillOnLambda() and getRenderProgressOnLambda().
  • We will maintain the Ruby SDK to ensure the fields stay in sync with the Node.js functions.
  • The fields in the input payload are snake_case versions of the Node.js field names.
  • Nested field names, e.g. s3_output_provder.accessKeyId have the original camelCase capitalization.
  • All fields of the response payloads are in camelCase like the original Node.js functions.
  • The maximum input payload size is around 60KB. The workaround for bigger payloads where they get uploaded to S3 is not implemented in the Ruby SDK.

Rendering a video and getting the progress

rb
require 'remotion_lambda'

client = RemotionLambda::Client.new(
  region: 'eu-central-1',
)

function_name = ENV.fetch('REMOTION_APP_FUNCTION_NAME')

payload = get_render_media_on_lambda_payload(
  composition: "still-helloworld",
  download_behavior: {
    type: "play-in-browser",
  },
  codec: "h264",
  input_props: {
    message: "Hello from props!",
  }
)

res = client.render_media_on_lambda(function_name, payload)
puts res
while true
  render_progress_payload = get_render_progress_payload(
    render_id: res["renderId"],
    bucket_name: res["bucketName"],
  )
  progress = client.get_render_progress(function_name, render_progress_payload)
  puts progress["overallProgress"]
  break if progress["done"]
  break if progress["fatalErrorEncountered"]
  sleep 1
end

Rendering a still

ruby
require 'remotion_lambda'

client = RemotionLambda::Client.new(
  region: 'eu-central-1',
)

function_name = ENV.fetch('REMOTION_APP_FUNCTION_NAME')

payload = get_render_still_on_lambda_payload(
  composition: "still-helloworld",
  input_props: {
    message: "Hello from props!",
  }
)

res = client.render_still_on_lambda(function_name, payload)
puts res
