Many thanks: will try the skype test later today --dave On 2020-09-07 5:23 a.m., Toke Høiland-Jørgensen wrote: Dave Collier-Brown writes: LWN said OK, but I'm stuck on the search for a striking test, one that resonates with "grandma". My next two thoughts, probably for the current long weekend, is either to call a loop-back number with Skype and/or ask Toke how he got "Big Buck Bunny" to suffer dropouts. I'd love to use the latter, as it aligns with the observation that this is a time when conference-call failures are driving my colleagues to drink (;-)) I assume you're referring to the Dash data included in the Polify paper, right? :) Not sure if I ever got it to drop out completely; just did some measurements of which bitrate it picked, and the context was airtime prioritisation, not so much the latency improvements. But anyway, the tests just used the reference dash.js[0] player, with a logger addition that Flent can parse[1]. I don't recall what exactly is needed on the server side to run this, but I think it's basically just dropping the right Big Buck Bunny tarball on a web server along with dash-logger.js from the Flent sources :) -Toke [0] https://github.com/Dash-Industry-Forum/dash.js/wiki [1] https://github.com/tohojo/flent/commit/6b83896cc0df1d468577ef0f35abbab6dd025c3f -- David Collier-Brown, | Always do right.
