Audio 为什么我在'；我试图在一行中多次将2个视频文件与第三个视频文件的音频合并？

我有一个视频文件，我想用第三个视频文件的音频与另一个视频文件连接，这5次一行。 唯一不变的文件是第一个视频文件。 所以我试着运行这个命令：

./ffmpeg.exe -i Video\\decompte.mp4 -i "Video\\Breaking Bad_OPENING_Opening.mp4" -i "TempVideo\\Breaking 
Bad_OPENING_Opening.mp4" -i "Video\\The 100_OPENING_Opening.mp4" -i "TempVideo\\The 
100_OPENING_Opening.mp4" -i "Video\\Stranger Things_OPENING_Opening.mp4" -i "TempVideo\\Stranger 
Things_OPENING_Opening.mp4" -i "Video\\Lucifer_OPENING_Opening.mp4" -i 
"TempVideo\\Lucifer_OPENING_Opening.mp4" -i "Video\\Black Mirror_OPENING_Opening.mp4" -i 
"TempVideo\\Black Mirror_OPENING_Opening.mp4" -filter_complex "
[0:0]scale=1280:720:force_original_aspect_ratio=1[v0]; 
[2:v]scale=1280:720:force_original_aspect_ratio=1[v2]; 
[4:v]scale=1280:720:force_original_aspect_ratio=1[v4]; 
[6:v]scale=1280:720:force_original_aspect_ratio=1[v6]; 
[8:v]scale=1280:720:force_original_aspect_ratio=1[v8]; 
[10:v]scale=1280:720:force_original_aspect_ratio=1[v10]; 
[v0][v2][1:a][v0][v4][3:a][v0][v6][5:a][v0][v8][7:a][v0][v10][9:a]concat=n=5:v=2:a=1[outv][outa]"
 -map "[outv]" -map "[outa]" 637342141280804229.mp4

但是，当我运行此命令时，会出现错误，但我不明白为什么：
