我正在尝试使用以下命令连接两个 MP3 文件。
ffmpeg -i "concat:19 Protein Drink (2007-10-21 Indianapolis IN).mp3|20 Sewing Machine (2007-10-21 Indianapolis IN).mp3" -acodec copy "19 Protein Drink - Sewing Machine (2007-10-21 Indianapolis IN).mp3"
在播放时，两个文件之间的连接文件总是出现中断/间隙/静音。我希望这是无缝衔接的（因为两首歌之间有过渡）。当我查询文件信息时，两个文件的持续时间元数据中都有一个“开始”标签（见下例 - 当前设置为“0.025056”）。
是否有工具可以删除此标签/元数据？
$ ffmpeg -i 19\ Protein\ Drink\ \(2007-10-21\ Indianapolis\ IN\).mp3
