Video not playing on "safari"

Video autoplay must be disabling safari to not play the video.

The initial above issue is resolved, but still the video won't (will play but won't show anything) play starting from second item of feature slide

Safari does not support the extension webm we are using.
Therefore, video files with different extensions are required.
Please check the support information below! caniuse webm info
That desktop safari issue is somehow resolved (on Version 15.1 (17612.2.6.1.1))

What you gotta see is safari on iphone / ipad
The same is true for iphone. Version 15 is also only partially supported, not 100% supported. (I confirmed that it works well when the extension name is mp4.)

Not true.

Of course it doesn't work on the current site! Because we are using only webm which is not properly supported by ios right now. We have to support multiple video files with multiple extensions like this one
All code required for preparation has been fixed. Just add an mp4 or ogg (anything!) file.
I changed the format to mp4, but an additional issue occurred that only works when the second video is not visible as shown below.
(in mobile safari, ios version 15.0.2)
-
when I see you at first

-
When I look back after scrolling

Even though I added the playInline property and changed the video format, one video that was not resolved was changed to a pure html5 video tag. This is explained in the documentation.
