[Story] Video are freezing and user need to tape a second time to play it #37523

Open llccrr opened 2 years ago

llccrr commented 2 years ago

Description

The video is freezing on the first frame of the video. It happens with cache="google" (dunno if it happens without) It seems to only occurs when the Story is embedded in an iFrame or maybe it's linked to some queryString

EDIT: I mapped it a long time ago, it was happening in the AmpStory Player, but now it also occurs in our custom Player so I edited the issue.

Reproduction Steps

Customer Website -> Click on the Round Bubble on MacOS Safari, re-try if you do not have the bug.

Have you been able to reproduce ?

mszylkowski commented 2 years ago

(Updating this issue with our offline discussion) would be useful to have an minimal demo with the open-source web player to debug this, otherwise it may be an issue with the viewer API integration of the Join Player (which you'd have to debug separately).

I do have the bug with an Open Source Player, but it seems actually slightly different since with the Open Source Player it freezes, but the autoplay keep going whereas with Join Player it freezes and the autoplay is also frozen Example with Open Source Player : https://6832h8.csb.app Video : https://user-images.githubusercontent.com/15107671/172565535-76a235c9-b204-455a-872b-1507d49252fd.mov

EDIT : A story without any player here where the same bug occurs (autoplay keeps playing): https://tajinebanane.my.join-stories.com/tee-shirt-diy-az4W_WU/

Refreshed 20+ times on the player and individual story (the last links you commented) without reproducing the bug so I doubt it's the same issue (on your player impl the story doesn't play 100% of times). I recommend checking the render_ method of the open source player to see if all the steps are handled properly:

So indeed it's not the same bug, the first one which happens 100% of time seems to be linked to the "auto unmute" the Stories in an iframe (not permitted on Safari) so it is on our side. However, there is still the bug that freezes with the autoplay that continues.
