저는 avchd 1080p 60fps 파일에 대해 ubuntu 14.04.4의 geforce 210 카드용 nvidia 드라이버 340.96을 사용하여 하드웨어 가속을 달성하려고 노력해 왔습니다.
kodi(16.0)와 VLC는 모두 끊기고 고르지 못한 사용 가능한 비디오를 생성합니다. 재생하는 동안 CPU 코어(코어 2 듀오 E6750)가 100% 및 40%로 실행됩니다. 누보 드라이버도 마찬가지다.
Windows 7에서는 완벽하게 재생되므로 하드웨어 문제는 아닐 것입니다.

답변1
새로운 Intel E3, E5 및 E7 CPU 칩에는 AVCHD 압축/압축 해제 기능이 내장되어 있습니다. 구형 CPU는 그럴 수도 있고 아닐 수도 있습니다. Windows는 이러한 기능에 액세스하는 방법을 알고 있지만 Linux는 기본 커널에 아직 이 기능이 없을 수도 있습니다.
