나는 아이폰에서 비디오를 녹화하고 vcodec hevc를 사용하여 .MOV 파일을 얻습니다. 그대로, 소프트 편집 시 재생할 수 없고 사용할 수 없습니다.
그래서 ffmpeg 명령을 사용하여 .mp4 파일로 변환하려고 했습니다.
ffmpeg -i input.MOV output.mp4
하지만 outpul.mp4는 여전히 재생할 수 없습니다(비디오는 없고 노래만 있음). 또한 vcodec 에 옵션을
사용하려고 시도했지만 결과는 동일합니다.-vcodech264
ffmpeg -i input.MOV -vcodec h264 output.mp4
다른 옵션(동일한 문제):
ffmpeg -i input.mov -c:v libx264 -c:a copy output.mp4
명령 출력:
me@my_pc:~/Test_vid$ ffmpeg -i input.mov -c:v libx264 -c:a copy output.mp4

답변1
호환되지 않는 비디오 코덱(HVEC는 호환 가능)을 고려하여 비디오 코덱을 다시 인코딩해야 합니다.
ffmpeg -i input.mov -c:v libx264 -c:a copy output.mp4
오디오 코덱은 다음을 사용하여 필터링해야 합니다.
-bsf:a aac_adtstoasc
잘라내기를 원하거나 그래픽으로 하고 싶다면 다음을 제안하고 싶습니다.비디오컷ppa로 가져올 수 있습니다.
https://launchpad.net/~jentiger-moratai/+archive/ubuntu/mediatools
설치하려면 다음을 실행해야 합니다.
sudo add-apt-repository ppa:jentiger-moratai/mediatools
sudo apt update
sudo apt install --no-install-recommends install videocut
업데이트
내 VideoCut 앱으로 테스트해 보면 다음과 같이 요약됩니다.
ffmpeg -i input.mov -c:v copy -c:a copy -bsf:a aac_adtstoasc -avoid_negative_ts 1 -shortest input2.mp4
이것이 ffmpeg muxer가 수행하는 가장 빠른 방법입니다. 패킷을 복사하는 동안 오디오 필터는 해당 컨테이너(mov 대 mp4)에서 오디오 코덱의 비호환성을 제거하는 데 사용됩니다. 마지막 2개의 스위치는 오디오 동기화에 사용됩니다.
위에서 언급한 대로 VideoCut은 이 작업을 자동으로 수행합니다. 내장된 "remux" muxer를 사용하면 잠재적으로 누락된 첫 번째 프레임을 처리할 수 있습니다(ffmeg는 처리하지 않음).
