안녕하세요. 도정진입니다.
카페에 정리되어 있는 착한유령님의 글과 구글 서칭을 통해서 결국에 QSV 트랜스코딩에 성공하였습니다.
아직까지 libmfx 를 pkg-config 과 연동을 하지 못하여 컴파일을 하지 못하고 있습니다.
(FFMPEG 를 컴파일 하려고 하면 libmfx 가 없다고 뜹니다. 이 문제를 어떻게 해결해야할지....)
그러나 이미 빌드된 바이너리를 가지고 동작을 해 보면 작동이 매우 잘 됩니다. 부정확한 부분은 덧글로 알려주시길 바랍니다.!!
시작합니다.
1. 하드웨어 호환성
QSV 는 intel ark 로 보시면 QSV 지원 여부가 나옵니다.
저는 I5-4350U 시스템에 설치를 하였습니다.
4350U 의 경우 지원한다고 나와 있습니다.
그러나 CPU 정보에서 QSV 가 지원된다고 나와 있어도 윈도우에서는 지원이 잘 되나 리눅스에서는 메이저급 CPU 만 지원이 되고 있습니다.
예를 들어서 N3150 의 경우 QSV 가 가능한 CPU 이지만 리눅스에서 사용할 수 있는 드라이버는 제공이 되지 않고 있습니다. 제가 생각해 보았을 때, 최소 I3 이상은 가야 QSV 가 리눅스에서 동작합니다. (윈도우 에서는 문제 없이 작동합니다.)
2. Intel Media Server Studio 버전 관련
다음으로 QSV 인코더 및 디코더를 사용하기 위해서는 인텔에서 제공하는 미디어 서버 스튜디오를 깔아야 합니다. 그런데 버전별로 지원하는 세대가 다르기 떄문에 맞게 다운받으셔야 합니다.
아래의 문서에 따르면 각 CPU 세대마다 필요한 버전은 아래와 같습니다.
https://software.intel.com/en-us/articles/driver-support-matrix-for-media-sdk-and-opencl
3세대의 경우 2015버전을 / 4세대의 경우 2015 2016버전을 / 5세대의 경우 2015 2016 2017 을 사용할 수 있다고 나오네요.
저는 4세대이기 때문에 2016버전을 사용하도록 하겠습니다.
intel media server studio 리눅스 파일들은 아래의 홈페이지에서 받을 수 있습니다.
https://software.intel.com/en-us/intel-media-server-studio
3. 전반적인 진행 과정
1. 미디어 스튜디오 압축 풀기
2. libdrm 설치
3. libva 설치
4. libmfx 설치
5. 커널 패치 및 컴파일 (5세대 부터는 필요가 없습니다. 백포트 커널 설치하시면 문제없이 작동합니다.)
- 이 부분은 이 글에서 다루지 않습니다.
6. libmfx 모듈 등록
7. ffmpeg 를 사용해 트랜스코딩 테스트
4. 의존성 패키지 및 인텔 미디어 서버 스튜디오 설치
의존성 패키지를 설치합니다. 다음으로 미디어 서버 스튜디오를 받으셨으면 압축을 풉니다.

5. libdrm , libva , libmfx 설치
설치에 들어가기 전에 말씀 드립니다.
아직 libmfx 설치를 정확하게 한 것인지 잘 모르겠습니다. 컴파일 할 때 libmfx 가 없다는 에러가 계속 뜹니다.
덧글로 지적해주시길 바랍니다.
libdrm 을 설치하겠습니다.
