Make chapter metadata show up in Quicktime X using ffmpeg

[Wowfunhappy]

Hi! I use the command-line version of ffmpeg to reencode and remux movies from time to time. However, whenever I try to play the files outputted by ffmpeg, Quicktime X on Mac is unable to see any chapter metadata, even if it was visible in the original file.

Strangely, if I do ffmpeg -i video-that-quicktime-thinks-has-no-chapters.mp4, ffmpeg shows me a list of chapters, causing me to believe that the chapter metadata IS still present, but that quicktime can no longer see it, for some reason.

Is there any way to make this metadata quicktime compatible?

You have to force mov as output file extension to be quicktime compatible iirc...

For chapters, you can find some help here (http://ffmpeg.org/ffmpeg-formats.html#Metadata).
