나는 내 것을 얻으려고 노력 중이야소니 A5100웹캠으로 작동리눅스, 구체적으로페도라 325.11.22-100.fc32.x86_64커널 에 . 이제 업그레이드할 때가 된 것 같은데, 제가 잘못하고 있는 부분은 없는지 먼저 여기부터 확인해 봐야겠다는 생각이 들었습니다.
다음과 같은인터넷 가이드v4l2loopback모듈 ffmpeg등을 포함하여 몇 가지를 설치했습니다 . 다음 스크립트를 사용하십시오.

( usbreset스크립트는 다음에서 제공됩니다.여기) 단일 프레임을 표시하는 일관된 방법이 있지만 카메라가 비디오를 스트리밍하도록 할 수 없습니다. USB 설정, 케이블, 캡처 카드, 카메라 설정 등이 모두 잘 작동합니다.윈도우, 그러나 다시 문제가 발생했습니다.리눅스.
위 스크립트의 출력은 cam다음과 같습니다.
