1553483 - Investigate how to cache sources and media files of raptor-youtube-playback benchmark via mitmproxy and tooltool

Status: NEW

(Testing :: Raptor, defect, P3)

Description

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Right now the tests are run with use_live_sites set to true, given that the media files are simply too large for us (~14GB) to cache them via mitmproxy in tooltool.

It means that all the files are hosted at https://yttest.prod.mozaws.net/2019/main.html?test_type=playbackperf-test (bug 1548062), and files will be fetched from a Github repository (bug 1553395) in a scheduled interval.

Ultimately we want to get rid of the live site mode, and cache all of them like for any other test via mitmproxy and tooltool.

This bug exists to investigate what's necessary to do.

Note that all the media files are complete movies even only the first 15s are getting played. As such trimming the files could save us a lot of space. But as raised by Eric in one of our streaming test meetings, it might also be valuable to explore if we want to have our own media files.
