[英]FFMPEG - Merge mp4 files and audio file
我有一个ffmpeg ,可以合并3个mp4视频,然后是另一个命令,该命令可以将音频添加到第一个命令的输出文件中。 命令如下:
ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -filter_complex "[0:v][1:v][2:v]concat=n=3:v=1" -preset ultrafast -crf 1 output.mp4
ffmpeg -i output.mp4 -i audio.mp3 -preset ultrafast -crf 1 final.mp4
反正有一个命令可以做到这一点吗? 我还想将音频添加到在第一个命令中创建的视频中。 这可能吗?
控制台输出为“ ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -i audio.mp3”
