PR to be made to this repo
Feel free to ask questions, but ask them publicly in the issue, and ping me on discord bwhm#6514 so I'll see it :)
Scope
Use puppeteer, or a similar free and open source tool, to create a script that mimics a user playing a video on play.joystream.org.
Each time the script runs, make the query:
curl 'https://query.joystream.org/graphql' -H 'Accept-Encoding: gzip, deflate, br' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'Connection: keep-alive' -H 'DNT: 1' -H 'Origin: https://query.joystream.org' --data-binary '{"query":"query {\n\tvideos (limit:1000000) {\n id\n duration\n media {\n id\n size\n isAccepted\n }\n }\n}"}' --compressed
and filtering out files where "isAccepted": false. Then, select 5 videos randomly to play, and log:
- when the test was run
- which videos were requested, and for each of these:
- from which distributor (URL) it's played from
- how long it took to get a response from the server
- duration/file size, and the time/speed it took to start playing
Play 20 sec or so, and measure how much of the video was buffered at 5, 10 and 20 sec.
As with images, get the latency to each of the distributors used and provide a summary of the test run.
Tool for Fetching Assets from the Player
Measuring the quality of service by the Distributors without proper tools is a very manual (and error prone) job.
First, we create a tool that fetches thumbnails from the front page. The tool has to be somewhat customizable, as in reality, users don't need to get every single asset at the same time.
