Playing HEVC served over HLS on iOS

Hello.
I'm trying to play HEVC live stream over HLS on my iPhone 8 ios 14 with VideoPlayer (or AVPlayerViewController)
H.264 is playing fine, but I can't get any HEVC stream to play.
I tried od device iPhone 8 with ios14 and iPhone 6s with iOS14 and also emulator (iphone 8 with iOS14) but none seem to work.
What am I missing?

That's what stream looks like.

Code Block #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:4
#EXT-X-MEDIA-SEQUENCE:420350
#EXTINF:4.320000,
file420350.ts
#EXTINF:3.840000,
file420351.ts
#EXTINF:3.840000,
file420352.ts
#EXTINF:4.320000,
file420353.ts
#EXTINF:3.840000,
file420354.ts

And this is from ffprobe

ffprobe.exe -show_format -timeout 10000 -loglevel trace "STREAM URL"
