Sitespeed results with waterfall,video and visual metrics for URLs or user journey scripts running MacOS Safari browser

[myanees284]

Your question

Hello Team, When I am trying to run the below command, the user journey works on safari browser. However it generates results with basic information like Performance Score, TTFB and FCP.

node /bin/sitespeed --multi test.js -n 1 -b safari

I do not see any information related to waterfall view, video and visual metrics like First visual change, speedIndex, VisualComplete, lastVisual change etc.

Is there anything I am missing? Please help

Hi @myanees284 if you install the decencies in https://www.sitespeed.io/documentation/sitespeed.io/installation/#mac then you can add --videoand --visualMetrics and you will get all the visual metrics like first visual change and speed index.

Hello @soulgalore. Thanks for your reply. I followed the above installation steps and tried to run again by adding the arguments node sitespeed.io/bin/sitespeed.js --multi test.js -n 1 -b safari --video --visualMetrics

I could see the safari browser getting opened and orange screen flashes and disappears leaving me with below error in the console:

I missed to install ffmpeg. Now I could get the visual metric details and video. However I do not see waterfalls details

thanks once again

Hi @myanees284 waterfall/HAR isn't implemented. The reason is that Safari doesn't support it, I wrote about here: https://github.com/sitespeedio/browsertime/issues/1777#issuecomment-1112565938
