我知道这似乎已经得到解答，但我无法合并两个音频文件和一个视频。
我的命令是：
ffmpeg -i file.mp4 -i file.aac -i file.mp3 -itsoffset 4 -i file_1.mov -itsoffset 10 -i file_2.mov -filter_complex "[0:v][3:v] overlay=10:main_h-overlay_h-10:enable=between(t\,4\,7) [v]; [v][4:v] overlay=10:main_h-overlay_h-10:enable=between(t\,10\,13) [v1]" -map "[v1]" -map 1:a -map 2:a -c:v libx264 -c:a libfdk_acc -shortest -y test.mp4
Ffmpeg 正确地创建了一个带有叠加层的新文件，但它没有添加两个音轨，只有一个。澄清一下，我想从第一个输入中获取视频，它只有一个视频轨道，并从 aac 和 mp3 文件中获取音频。我的错误是什么？
这是我的完整控制台输出：
ffmpeg -i file.mp4 -i file.aac -i file.mp3 -itsoffset 4 -i file_1.mov -itsoffset 10 -i file_1.mov -filter_complex "[0:v][3:v] overlay=10:main_h-overlay_h-10:enable=between(t\,4\,7) [v]; [v][4:v] overlay=10:main_h-overlay_h-10:enable=between(t\,10\,13) [v1]" -map "[v1]" -map 1:a -map 2:a -c copy -c:v libx264 -c:a libfdk_aac -shortest -y test.mp4
