Добавление нескольких аудиовходов в видео с ffmpeg не работает

Я пытаюсь добавить несколько аудиовходов в видеофайл, который не содержит звука. Следующая команда добавляет ' audio1.mp3 ' к видео, но не удается добавить второй и третий.

ffmpeg -y -i video.mp4 -itsoffset 00:00:05 -i audio1.mp3 -itsoffset 00:00:10 -i audio2.mp3 -itsoffset 00:00:15 -i audio3.mp3 -map 0:0 -map 1:0 -map 2:0 -map 3:0 -c:v copy output.mp4

полный вывод на консоль:

ffmpeg -y -i video.mp4 -itsoffset 00:00:05 -i audio1.mp3 -itsoffset 00:00:10 -i audio2.mp3 -itsoffset 00:00:15 -i audio3.mp3 -map 0:0 -map 1:0 -map 2:0 -map 3:0 -c:v copy output.mp4

все отображенные аудио потоки были включены.

для вывода в один поток используйте amix фильтр.

ffmpeg -y -i video.mp4 -i audio1.mp3 -i audio2.mp3 -i audio3.mp3
          -filter_complex "[1]adelay=5000|5000[a];
                           [2]adelay=10000|10000[b];
                           [3]adelay=15000|15000[c]; 
                           [a][b][c]amix=3[a]"
          -map 0:v -map "[a]" -c:v copy output.mp4
