すでに回答されているようですが、2 つのオーディオ ファイルと 1 つのビデオを結合することはできません。
私の命令は:
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 はオーバーレイ付きの新しいファイルを正しく作成しますが、2 つのオーディオ トラックは追加されず、1 つのみ追加されます。明確にするために、ビデオ トラックが 1 つしかない最初の入力からビデオを取得し、aac ファイルと mp3 ファイルからオーディオを取得したいと考えています。私の間違いは何でしょうか?
これは私の完全なコンソール出力です:
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

私の直感では -map オプションが原因だと考えましたが、この記事ではそれが確認されているようです。
