Check the docs for your email client or google it? If you're using gmail in 
a browser, click on the three dots at the bottom to expand the quoted text, 
then edit from there.

And if you haven't already, take a look at 
https://ffmpeg.org/mailing-list-faq.html.

"homebrew version"?? Where are you getting ffmpeg? You can get up-to-date 
macos builds at https://ffmpeg.zeranoe.com/builds/macos64/ and 
https://evermeet.cx/ffmpeg/  (both linked from 
https://ffmpeg.org/download.html). But.... see below...

Please provide the -entire- command output. It's very hard to debug a 
problem with almost no information.


 From the original email

Are you running ffmpeg on the iphone or on a desktop/laptop? That's very 
important to know. Have you tried multiple videos? With that error, it's 
possible that the video wasn't properly closed when recorded.

Later,
