Thanks for your reply.
I will go through the test from that link you shared, but i do not believe is a key DRM error as the content can be decrypted correctly. Dropped frames start showing up after around 4-5 minutes of smooth playback. I'm not using IV as you can see in the following EXT-X-KEY from my URLs.
#EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://private.com/streaming/getckc?AccountId=lgilab5aitc&CrmId=lgilab5aitc&ContentId=PRIVATE&KeyId=6d10b094-f812-3cc8-a7d5-82c69ba07ff2",KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1"
Also as i mention before, lower resolutions on HEVC do playback correctly. AVC do playback correctly on 1080p50, all are encrypted in the same way compare to the HEVC streams, using the same content ID, etc.
