Hi,

just generated a HDR10 MVHEVC file, mediainfo is below:

Color range : Limited

Color primaries : BT.2020

Transfer characteristics : PQ

Matrix coefficients : BT.2020 non-constant

Codec configuration box : hvcC+lhvC

then generate the segment files with below command:

mediafilesegmenter --iso-fragmented -t 4 -f av_1 av_new_1.mov

then upload the segment files and prog_index.m3u8 to web server.

just find that can not play the HLS stream on Safari...

the url is http://ip/vod/prog_index.m3u8

just checked that if i remove the tag Transfer characteristics : PQ when generating the MVHEVC file.

above same mediafilesegmenter command and upload the files to web server.

the new version of HLS stream is can play on Safari...

Is there any way to play HLS PQ video on Safari. thanks.
