Recent Downloaded Meeting Recordings no longer playing on QuickTime

Hello!

Is the file still being downloaded as an mp4 file?  This should be playable within quicktime.

Hello!

I'm sorry it's giving you trouble.  It seems to be the Quicktime doesn't support all mp4 files.  An alternative would be to use a different media player.  Check out this article: https://www.softwarert.com/quicktime-player-cant-open-play-mp4-mac-vlc/

Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.

Thanks!  Rick

I'm having this same issue with a recording from a year and a half ago. Same error message. VLC player does not fix the issue. 

Did something change with the latest updates for Zoom to cause this problem? 

What other solutions might I try? 

I'm also having this issue. Not sure what to do. Quicktime and VLC both fail. When the file is loaded in VLC it shows up as 00:00 duration.

I am having this same issue. I tried both Quicktime and VLC. Quicktime shows me the same error (will not play) and VLC shows the videos with a duration of 0:00 and will not play them. I have watched these same video files previously in Quicktime. All the files are hosted locally on my PC. 

Can anyone offer any potential solutions? I have dozens of hours of training videos that I can no longer access.

Hate to revive an old thread, but I had this issue too and the only solution I found was to re-encode the video in Handbrake. The new video created by Handbrake worked fine, although even Handbrake initially had an error being unable to decode the source video. I chose to reencode the audio too instead of using the passthrough option, and that worked.  

Like ​@mbaker1085, these videos are saved locally on my PC (via Dropbox) and I’ve watched them before. Now none of them open, not even in VLC which has always played anything I’ve thrown at it. In VLC, I could hear the audio, but no video at all. Neither Windows’ “Media Player” nor classic “Windows Media Player” could play the files, although I could play the videos in Dropbox online (just not after downloading them) so I had hope.
