Node-Express Video Transcoder API

A simple node-express API that lets you transcode videos and generate corresponding.hls and .ts files.

• upload videos to the server
• download the transcoded result
• upload the transcoded files to AWS S3
• access the video through AWS Cloudfront CDN

• run npm i to install all project dependencies.
• run npm run dev to start the dev server.
• v1.0.0: add video(s) in './src/videos/raw folder. For ease, there is already a video and its transcoded files added in ./src/videos folder. All you need to do is open the ./index.html file.

• Once you have the project running on localhost, upload a new video file using the POST /transcode/new endpoint.
• Once the video gets uploaded, transcoding starts immediately and just like in v1.0.0, generated output is stored in the ./src/videos/transcoded folder.
• Once transcoding is completed, the uploaded file is removed from the local fs.

• copy the complete video name, including the file extension, of the file that you want to transcode, say my-video.mp4.
• for v1.0.0, you can either use your browser or terminal to send a GET request to htp://localhost:4000/transcode/new/my-video.mp4

• in the ./index.html file, change the src value for the <video></video> element to point to the .hls file for your video.
• open the .html file and the network tab (in the dev tools), side by side.
• you will be able to see multiple requests being sent for .ts files, which is nothing but the browser requesting for more chunks as the video keeps playing.
• stop playback and no more chunks will be fetched.
• skip to a new video position and a new chunk will be fetched.
• jump back to a point in video which has already played and you'll see that the chunk was loaded immediately from disk cache. thing.
