我正在尝试将立体声背景音乐与单声道画外音音频合并，并进行音量调节和侧链处理，以便在播放画外音时降低音乐音量。此命令以前工作正常。没有任何变化。但对于我的新画外音文件，它抛出了以下错误。我已经检查了媒体文件中的画外音 mp3 文件属性，包括旧的（以前有效的）和新的，它们完全相同。有什么建议可以帮忙吗？我尝试添加各种格式过滤器的组合，但不幸的是没有帮助。
我可以让它与 amix 而不是 amerge 一起工作，但是 amix 的输出质量很差，所以这也不是一个选择。
画外音文件属性：
Format : MPEG Audio
Format version : Version 2
Format profile : Layer 3
Duration : 1 min 25 s
Bit rate mode : Constant
Bit rate : 32.0 kb/s
Channel(s) : 1 channel
Sampling rate : 24.0 kHz
Compression mode : Lossy
Stream size : 334 KiB (100%)
FFMPEG 命令：
ffmpeg_command = [
'ffmpeg',
'-i', background,
'-i', voiceover,
'-filter_complex', '[1:a]adelay=5000|5000,volume=1.5,apad[a];[0:a]volume=0.7[b];[a]asplit=2[sc][mix];[b][sc]sidechaincompress=threshold=0.05:ratio=20:level_sc=1:release=500:attack=1[compr];[compr][mix]amerge',
'-vn',
'output.mp3'
]
现在抛出错误：
