Bug with MP4 Sharing

[MontrealRussian]

Hello all,

We have stumbled across a bug with MP4 video sharing. Some videos, inexplicably, refuse to work with this feature.

For instance, here is a link to one video that works great. And here is another video that does not. Instead of showing, it just displays a black screen in Zoom. Both videos can however be opened with any other video player; they are simply a 1-second video containing an image.

How would we go about fixing this issue?

Hi @MontrealRussian 

Your two videos are different resolutions and bitrates. Maybe that has something to do with it?  Not sure.

Agreed @Rupert ; although the support docs claim that Zoom downscales the videos if necessary, so I wonder if there's a hidden maximum bitrate or something like that that isn't mentioned anywhere

If ever anyone finds this and is interested, Zoom support has confirmed to us that this is actually a bug, and that a fix should be released sometime this month.
