Chromium 브라우저를 사용하여 파일을 열려고 하는데 재생 버튼이 활성화되지 않는 것 같습니다.

VLC 로그로 돌아가서 "잘못된 NAL 유닛 4, 건너뛰기.", "libdvbpsi 오류(PSI 디코더): TS 불연속성 for PID 0(수신 11, 예상 1)"과 같은 몇 가지 오류를 인터넷 검색해 보고 몇 가지 포인터를 시도했습니다.
- VLC.org 포럼우편 엽서libdvdcss2를 설치하는 것이 좋지만 내 시스템에서는
E: Package 'libdvdcss2' has no installation candidate. - ffmpeg를 사용하여 비디오를 다른 형식으로 변환해 보았지만 이 명령은 성공한 것처럼 보였지만 결과
mpeg파일은 여전히 재생할 수 없습니다. 이 명령은 VLC를 사용하여 복사할 때와 동일한 경고를 많이 생성합니다.

ts나는 운이 좋든 없든 파일 확장자의 이름을 바꾸려고했습니다 mp4.
Linux에서 이 mp4 파일을 어떻게 재생할 수 있나요?
답변1
내 Linux Mint 21 Vanessa 셀룰로이드에서 Nvidia 가속을 사용하면 동영상이 제대로 재생됩니다.
어쨌든 CAS가 지적했듯이 다음을 사용할 수 있습니다.https://handbrake.fr/이 비디오를 원하는 형식으로 변환하세요.
내 생각엔 시스템에 일부 라이브러리가 없거나 VLC가 이 형식에 잘 적응하지 못하는 것 같습니다.
