Description (last modified by 0xdd-co)
I noticed slightly slower HEVC encoding using ffmpeg/x265 on my MacBook Pro compared to Handbrake (~3-5 fps difference encoding 4K footage). When I run x265 -V, I noticed the following:
`
x265 [info]: HEVC encoder version 0.0
x265 [info]: build info [Mac OS X][clang 13.0.0][32 bit][noasm] 8bit
x265 [info]: using cpu capabilities: none!
`
Seems like the Handbrake build has NEON listed under cpu capabilities, which might account for the slightly faster encoding time.
