H264(AMF), HEVC(AMF) 옵션 도움말

샤나 홈페이지 매개변수 도움말 섹션이 업데이트되면서 H264(AMF), HEVC(AMF) FFmpeg 명령행(command-line) 옵션 도움말이 사라져 버렸습니다. (FFmpeg 공식 문서에도 이 부분은 누락돼 있습니다.)

그래서 FFmpeg 실행 파일에서 해당 인코더들의 옵션을 직접 뽑아서 올립니다. (2020년 1월 N-96336 버전 기준인데, 샤나인코더 5 버전 내장 FFmpeg 라이브러리와 다를 게 없을 겁니다.)

매개변수 창(F8)의 인코딩 설정에서 적용할 수 있는 옵션들로, 본인의 하드웨어 사양에 따라 설정이 조금씩 달라져야 합니다.

AMD 그래픽 카드를 소유하신 분들은 인코딩 커스텀 설정하시는 데 참고하시기 바랍니다.
