Comment (by john123):

 Thanks, so are you saying Android Chrome (which is the only browser I
 could find that accepts this ffmpeg output) is broken also?  Ie, perhaps
 no browser supports what ffmpeg is doing here - but you're saying ffmpeg
 is correct and every browser is broken?

 More importantly for my immediate case (and for anyone else stumbling on
 this critical bug), is there some other AV1 format command line options
 that ffmpeg can output and get correct results across all modern browsers?
