h.265 - Raspberry PI 4 (settings, levels, profile, compatibility)

Post by unknown User »

Hi,

for the previous raspberries has been given a certain h.264 profile to ensure compatibility for smooth playback up to 1080p (high profile @level 4.1), irrespective from quality or compression settings. Over the years this has been the perfect way to build files for R PI.
Nowadays the R PI 4 supports hardware decoding for h.265 up to 2160p. Is there a respective kind of leveling or profiling for h.265 encoding in handbrake?

Well, surely the RPi developers would know what the built-in ASIC can decode? I couldn't find it quickly on the website, so you'll have to ask somewhere, I guess maybe they have a forum of their own.

A quick googling leads to this document which says:
The H.265 / HEVC decoder is a HEVCv2 Main 4:4:4 10 design supporting bitstreams up to profile 5.1. Maximum picture size is 4096 x 4096.
So Main 10 profile up to level 5.1.

But if I'd ask in their forum for proper settings in handbrake, where do you think would they delegate me? :D

Nope, a quick googling leads to several hundreds url's with thousand fragmented informations. That's why a forum is build for and why people use it. For questions and discussions :wink:

But thank you for the meaningful part of your answer.

6th hit with very reasonable keywords, no need to look at hundreds or thousands.
