Merci Romain!
This helped me refine my search and discover hls_segment_type option:
ffmpeg -i ../Big_Buck_Bunny_1080_10s_30MB.mp4 -c:v libvpx-vp9 -f hls
> -hls_segment_type fmp4 bar.m3u8

This produces .m4s files and vlc will play the m3u8 file just fine. It
doesn't seem to work with open source web players like hls.js though. I
get this error:
> HUNK_DEMUXER_ERROR_APPEND_FAILED: Video stream codec vp9 doesn't match
> SourceBuffer codecs.
However it DOES work with Theo:
https://www.theoplayer.com/test-your-stream-hls-dash-hesp
Also found this from Theo team:
https://www.theoplayer.com/blog/vp9-support-now-possible-on-apple-devices-and-all-major-platforms
So maybe this is just a hls.js config issue now.
Cheers,
Geoff
