1610012 - Generate timestamp annotated visual metrics video as part of vismet tasks

Status: RESOLVED FIXED

(Testing :: Performance, enhancement, P3)

Description

[Nick Alexander :nalexander [he/him]]

Right now, the browsertime (Raptor) performance testing jobs capture video and feed that video into vismet visual metrics tasks. The captured video is essentially unprocessed. Browsertime and the surrounding toolchain can annotate the video with timestamps and key events. This ticket tracks making the vismet tasks expose such annotated visual metrics videos.

(We want to keep all of the video processing out of the actual perf testing jobs, since those are very expensive to run due to limited device pools.)

I'm a big fan of this feature, enabled by --videoParams.addTimer
Unfortunately Sean and I found that enabling it on variable framerate videos is distorting the timing in the resulting video.

Looks like Peter is already on it though :)

This was added in an unknown bug (I believe it happened as part of the visual-metrics rework, or a browsertime update that changed the defaults), and we have annotated videos available for browsertime tasks that produce videos.
