Code Pipeline

Demo App

CDK

# install cdk
$ npm i aws-cdk

# bootstrap cdk
$ cdk bootstrap --cloudformation-execution-policies arn:aws:iam::aws:policy/AdministratorAccess aws://<account>/<region>

# if you want to use aws credential profile
$ cdk bootstrap --profile <your profile> --cloudformation-execution-policies arn:aws:iam::aws:policy/AdministratorAccess aws://<account>/<region>

Deploy

FFmpeg

This repo uses ffmpeg for extracting thumbnail image from source video. If you want to use this, you have to get the binary from the web. I prepared the script.

$ nx run infra:ffmpeg

# The binary must to commit and push codecommit repository
$ git add -A
$ git commit -m "fix: add ffmpeg binary"

# build infra packages
# it depends rust packages, So you have to prepare rust environment.
$ nx build infra

# on packages/infra
# aws credential setup required.
$ cdk deploy PipelineStack

# or use profile
$ cdk deploy PipelineStack --profile <your profile>

# After deploying the stack, then the CodeCommit repo will be created.
# If you want to deploy this app, you have to push this repo to the CodeCommit repo.
# If you use 
$ git remote add codecommit <CodeCommit-Repo>
$ git push codecommit main

Usage

Just upload video file to s3 that is generated by CDK. Then the video will appear on Demo app. Video file s3 key must follow the following structure.

video/myvideo.en-US.mp4

• "video" is s3 key prefix for upload to s3. Only the video that include video prefix will be triggered by lambda.
• "myvideo" will be the title.
• "en-US" is language code that used by transcribe. Refer this link.
• "mp4" is the file's extention. currently only mp4 and mov are supported.

You can access on demo app through the endpoint of deployed api gateway.

Search Engine

This sample use tantivy for searching subtitle. In particular, Among non-Latin languages, Korean is only supported (I used this).
