Introduction

EN

OVP(online video platform) mean that online transcoding, packaging and hosting service with video file upload to online storage or cloud system.
Internet speed was increase and many internet user prefer to streaming service for Mobile, web, OTT than service from over-the-air television networks. but streaming service use OVP or solution for start streaming service with Mobile, web, OTT(over the top). such as OVP and some solution require many spend money for streaming service.
Famous OVP business company is brightcove.com, mux.com, dacast.com, vimeo.com, Dacast.com, Amazon elastic transcoding and Wowza solution.
CW-OVP project will commit helping for who want ready for streaming service.
This is why CW-OVP project was built.

OVP(online video platform)란
온라인 저장소 또는 클라우드에 비디오 파일을 업로드하여 트랜스코딩과 페키징 처리후 호스팅 서비스를 제공함을 말한다.
인터넷 속도의 발달과 사용자들의 요구로 많은 스트리밍 서비스가 생겨나고 있고, 기존의 방송사들도 흐름에 따라 Mobile, web, OTT(over the top) 셋탑기기의 스트리밍 서비스를 제공하기 위해서 OVP(online video platform)이나 솔류션을 많이 사용하고 있다.
대표적인 해외 OVP는 brightcove.com, mux.com, dacast.com, vimeo.com, Dacast.com, Amazon elastic transcoding 등 서비스들이 존재하며 솔류션으로는 Wowza가 존재한다.
이에 CW-OVP 프로젝트를 오픈소스로 개발하여 기업이나 단체, 개인에 도움이 되고자 한다.

Tech Stack

what use	description
FFMPEG	video transcoding, packaging
h.264	Codec
HLS	Protocol
Ruby on Rails	web framework, websocket(action cable)
Redis	queue, pub/sub
Sidekiq	background job, queue
Postresql	database
Docker, docker-compose	install environment
Docker Swarm	Clustering
Kubernetes	Clustering

• you can choose Docker swarm or Kubernetes(kops or EKS) for Clustering

Feature

• Clustering ffmpeg worker with sidekiq on Docker swarm or Kubernetes
• Transcoding, Packaging with ffmpeg for HLS
  • Generated multiple m3u8 for Adaptive Streaming
• Extract 10 random Thumbnail images during video packaging
• AWS S3 for stored video, thumbnail assets
• AWS Cloudfront for CDN
• Real time base on web UI with websocket(Action Cable), ruby on rails
• Open source (GPL-2.0 License) and Free, but need hardware…

System Structure

• If your node for database that got fault or something wrong, You can lost persistent in database. that's why I recommend AWS RDS for postgresql.

Getting started

Storage config

• AWS S3 Storage
  1. How to make s3 bucket for AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY
     • https://www.changwoo.org/x1wins@changwoo.net/2019-10-23/Upload-file-to-S3-with-AWS-CLI-d12442012c
  2. How to make cloudfront url for AWS_CLOUDFRONT_DOMAIN
     • https://www.changwoo.org/x1wins@changwoo.net/2019-10-23/using-cloud-front-with-s3-51d2eb17bb
  3. Update .env.dev.s3 file for s3, cloudfront
     1. open .env.dev.s3
     2. add below of code and update each value

            AWS_ACCESS_KEY_ID=[Change key id]
            AWS_SECRET_ACCESS_KEY=[Change access key]
            REGION=[Change region (us-west-1 or us-west-2 or us-east-1...)]  
            BUCKET=[Change bucket]
            CDN_BUCKET=[Change cdn bucket]
            AWS_CLOUDFRONT_DOMAIN=[Change cdn domain]
        

     3. Check config

        docker-compose --env-file .env.dev.s3 config
        

  4. ignore changed .env.dev.s3 file when git commit

        git update-index --assume-unchanged .env.dev.s3
     

How To Run Development mode with Docker-compose

1. Download source
   1. git clone https://github.com/x1wins/CW-OVP.git
   2. cd ./CW-OVP
2. Build and Run
   1. docker-compose --env-file .env.dev.s3 up --build -d
   2. docker-compose run --no-deps web bundle exec rails webpacker:install
   3. docker-compose --env-file .env.dev.s3 restart web
   4. docker-compose run --no-deps web bundle exec rake db:create
   5. docker-compose run --no-deps web bundle exec rake db:migrate
   6. docker-compose run --no-deps web bundle exec rake db:create RAILS_ENV=test
   7. docker-compose run --no-deps web bundle exec rake db:migrate RAILS_ENV=test
3. Restart for updated code
   1. git fetch origin develop
   2. git reset --hard origin/develop
   3. Restart web, sidekiq

      docker-compose --env-file .env.dev.s3 restart web
      docker-compose --env-file .env.dev.s3 restart sidekiq
      

4. Unit testing with rspec

   docker-compose run --no-deps web bundle exec rspec --format documentation
   

5. Console

   docker-compose run --no-deps web bundle exec rails console
   

6. Troubleshooting
   1. when I got bundle error such as minemagic
      1. Log of minemagic gem error

         Step 10/16 : RUN bundle install
         ---> Running in 578d62fab6ac
         Fetching gem metadata from https://rubygems.org/............
         You have requested:
          mimemagic ~> 0.4.1
         The bundle currently has mimemagic locked at 0.3.5.
         Try running `bundle update mimemagic`
         If you are updating multiple gems in your Gemfile at once,
         try passing them all to `bundle update`
         ERROR: Service 'web' failed to build: The command '/bin/sh -c bundle install' returned a non-zero code: 7
         The command "docker-compose build" failed and exited with 1 during .
         Your build has been stopped.
         

      2. Solution

         docker-compose run --no-deps web bundle update mimemagic
         

   2. Keep latest gem for defense vulnerability

      docker-compose run --no-deps web bundle update
      docker-compose run --no-deps web yarn upgrade --latest
      

   3. no space left on device

      2. Log

      3. Solution

         % docker system prune
         WARNING! This will remove:
           - all stopped containers
           - all networks not used by at least one container
           - all dangling images
           - all dangling build cache
