Question

我正在尝试在特定时间使用ffmpeg将音频添加到MP4文件中，最终我还希望音频只播放到某个点，所以如果你能帮助它也会很棒，否则如果你可以帮助我找出造成这个错误的原因。

我使用的论据

-y "E:\Documents\Content Bar/Photo Booth\PhotosDrop\2018-05-15 14-01-16OUT.mp4" -itsoffset  -i "E:\Downloads\wetransfer-250b26\05 Call of Love.mp3" -map 0:0 -map 1:0 -c:v copy -shortest "E:\Documents\Content Bar\Photo Booth\PhotosDrop\2018-05-15 14-01-16OUTOUT.mp4"

这会导致以下错误：

Answer 1

好的，所以我使用以下命令

计算出来

-i "E:\Documents\Content Bar/Photo Booth\PhotosDrop\2018-05-15 14-01-16OUT.mp4" -i "E:\Downloads\wetransfer-250b26\05 Call of Love.mp3" -filter_complex "[1]atrim=end=20,asetpts=PTS-STARTPTS[aud1];[aud1]adelay=6000|6000[aud];[0][aud]amix" -c:v copy out.mp4

在某个偏移量处使用ffmpeg将音频添加到mp4，输出文件＃0不包含任何流
