같은 폴더에 test.m4a와 test.srt라는 파일이 있습니다.
m4a에 자막을 구우려면 어떻게 해야 하나요?
내가 얻는 결과는 다음과 같습니다.

좋다위키 페이지에서 언급--enable-libass, 자막 필터가 작동하려면 ffmpeg 빌드를 컴파일해야 합니다 . 귀하의 빌드는 불행히도 그런 기능이 없는 것 같습니다.
가장 쉬운 방법은 다음을 사용하는 것입니다.홈브류.
그런 다음 ffmpeg를 설치하십시오.
brew install ffmpeg
그런 다음 다시 시도해 보세요.
ffmpeg -i test.m4v -vf subtitles=test.srt -c:a copy out.m4v
꼭 읽어보세요H.264 인코딩 가이드출력 품질을 설정하는 방법을 알아보세요.
예제의 파일과 같이 DRM으로 암호화된 파일은 변환할 수 없습니다(비디오 코덱 참조 drmi). 이것은티켓 오픈ffmpeg의 경우 해결될 가능성이 낮습니다.

나는 Parallels에서 실행되는 Windows에서 vidcoder 1.5.22를 사용하게 되었습니다.
