Hardware-Accelerated Video Encoding | 0.16.4.0+

OvenMediaEngine Enterprise를 RPM/DEB 패키지 파일로 설치할 경우, 해당 장비에 NVIDIA 그래픽 카드 또는 Xilinx Alveo U30MA 카드와 드라이버만 설치되어 있으면 Hardware-Accelerated Video Encoding이 자동으로 활성화됩니다. 그래픽 드라이버는 RPM/DEB 패키지 설치 후에도 재설치, 업데이트 및 삭제가 가능하며 프로그램 실행에 영향을 주지 않습니다. 이 문서에서는 지원 버전, 지원 코덱, 드라이버 설치 및 확인 방법에 대해 설명합니다.

Hardware-Accelerated Video Encoding 활성화 확인 방법

RPM/DEB 패키지와 드라이버 설치가 완료되면, OvenMediaEngine에서 드라이버가 정상적으로 로드되어 Hardware-Accelerated Video Encoding 기능이 활성화되었는지 확인해야 합니다. 이를 확인하기 위해 OvenMediaEngine 의 로그 파일로부터 확인 할 수 있습니다.

$ cd /var/log/ovenmediaengine
$ cat ovenmediaengine.log | grep transcoder_gpu
