Please hear me out. I know and I have read that Raspberry Pi 3+ does not support HEVC. HOWEVER, sometime in the last 2 years, I recall (without knowing that it was supposedly impossible) that I had applied an update to LibreELEC (I think a regular update) and previously unplayable HEVC videos were playing on my Raspberry Pi 3+.
Am I mistaken on some aspect of this? I'm now finding that my Pi is unable to play HEVC videos again without at least some stutter but I can't pinpoint when this occurred or if I was mistaken all along.
I realize that I am more than likely wrong in my initial takeaway but this memory is so clear to me and for the sake of my sanity, I had to ask the question.
Thank you in advance for any help!
