[FFmpeg-user] global_sidx on IOs12

[James Northrup]

i found this interesting feature of apple's iron fisted app-store policy.
https://github.com/google/shaka-player-embedded/issues/36#issuecomment-460742232


somethign like HLS is required for apps that present video streams longer
than 10 minutes.

so what would really be helpful is to find out if anyone on this list has
tested any of the ffmpeg-dash muxer  HLS permutations with apple hardware,
and if so, what's the trick.

thanks
Jim
