스트림 2를 제거하지 않는 이유는 무엇입니까? 내가 무엇을 놓치고 있습니까?

답변

일반적으로 왜 그것이 매핑되지 않는지 모르겠습니다. 그러나 이에 대한 해결 방법을 찾았습니다.

ffmpeg -i 01300.mov -filter_complex "[0:v]null[video_out];[0:a]anull[audio_out]" -map [video_out] -map [audio_out] out.mov

ffmpeg가이 세 번째 스트림을 올바르게 맵핑 할 수없는 것 같습니다.

답변

Google 검색에 등장하므로 다른 사람들이 솔루션을 찾는 데 도움이 되므로이 답변.

이 티켓은 https://trac.ffmpeg.org/ticket/5492 로 수정되었으며 -write_tmcd 0ffmpeg 명령 에 추가하여 트랙을 제거 할 수 있습니다 .

이것은 특별히 Data (tmcd)트랙입니다. 기타 (자막, 일반 데이터 등) 중 어느 하나의 조합을 위해 -dn, -map -0:d유사한 명령을 도와야한다.
