While COVID-19 became set back for many companies, it also brought new opportunities for certain industries. OTT and Video On Demand platforms are one of them. Schools, Colleges, Institutions started looking for an option to have something for the students to let them continue the studies while being at home in this pandemic.
While Working on a client project at TheCodework, Architecting Video On Demand platform was coming out to be very costly comparing Video On Demand by AWS. Although, using AWS is a very effective solution with greater performance but, that too comes with a price for each of the services. We rather choose Digital Ocean instead of with its Block Storage Volumes to store our video files. I must say it isn't a bad solution comparing the reduced monthly cost.
The architecture of the project was quite simple with no complexity at all. We were using Laravel application for the backend Admin and APIs with Queues handled by Redis, SQL Database, and 4 Core CPU Server.
To stream videos on Mobile Devices or on the Web portals, Dynamic Adaptive Streaming over HTTP (DASH) which is a bitrate streaming technique and being popular these days. The popular ones are MPEG Dash and Apple's HLV.
When the admin uploads a video, we let Redis Queue process the video transcoding on the server. We restricted the admin to provide MPEG-4 video for the upload, and then the Queue would handle the transcoding and creates the Streamable MPEG Dash Video file. We used Laravel Wrapper to interact with the installed MPEG Dash binary and start the process.
Digital Oceans servers come with optimal storage but, to store MPEG Dash files we needed more storage that. So we decided to go with Digital Ocean Volumes that easily get mounted to the Droplet. Additionally, we can increase the size of the volume anytime we need so it is quite flexible to use.
While creating volumes on the Digital Ocean, please make sure you do not automatically mount it to the droplet rather, select the Manually Format * Mount option while creating Volume. To find about mounting, you can refer to https://www.digitalocean.com/docs/volumes/how-to/mount/ blog of Digital Ocean and mount it to your
