To send videos, they need to be in a format acceptable on WhatsApp Web
VIDEO FORMAT
mp4 codec libx264
And use Chrome instead of Chromium

whats the differences between fetching the buffer using chromium vs chrome??

I didn't say nothing about fetching but read the guide to understand why you have to use Chrome instead of Chromium

oh,, sorry, i think i misunderstand it

okay everything works now, thankyou!

at first i thought the problem is within the buffering process (i also use puppeteer to fetch the video)

Need to clarify, so supported video format is mp4 container with h264? Also the audio codec could be aac nor mp4a?
