Macbook Pro 2017 - 4K HEVC choppy

[herkod]

Hello!


So... after Apple announced that they now supported HEVC-decoding I decided to buy a Macbook Pro 15inch 2017 (I7 Kaby Lake 2,8gHZ, graphic: AMD Radeon Pro 555).

Upgrade to High Sierra

Done but it doesn't help...

VLC? I suppose media players must take advantage of HEVC coded, maybe for now only QuickTime is doing it. Are you playing the file from a fast storage?

Tried to watch a 2160P-movie (70gb remux, HEVC, HDR 10-bit, bit rate: 50 mb/s) in Kodi and it's all choppy. CPU is around 400 percent. Any suggestion what's wrong? I've tried different media players but it's the same as Kodi (or worse).

If you are remuxing an HEVC file use Subler and make sure to set the 'Force Quicktime Compatibility' setting. This sets the FourCC identifier to the correct parameter. Then use QT for playing. Plays perfectly on Apple TV 4k with Plex for me as well as OSX.

Ikir: Yes, it's on the desktop. Tried VLC 2.2 and 3.0. Works better with 3.0 but not smoothly.

Nylon: Thanks for the tip. I tried Subler while ago and a 75gb file was down mixed to 23gb. It's not lossless compression, right?

If you are setting the correct parameters when adding the files as 'Passthru' it is lossless. Only if you specify conversion to another audio format will it down mix. Video is untouched.
