我正在尝试通过提取元数据文件并按照以下方法使用 ffmpeg 将自定义章节添加到 mp4 文件中本指南。
但是，当我编辑元数据文件以更改任何章节名称时，重新添加元数据的第二个命令会忽略对章节的更改并保持原样。它肯定正确地读取了元数据文件，因为当 ffmpeg 打印出两个输入文件的数据时，它会打印 mp4 的流和元数据文件的所有元数据，所有章节都正确格式化和解析。
但是，一旦创建输出文件，它就会再次使用旧的章节名称。如果我更改其他元数据，则会出现这种情况（例如标题键或艺术家键），但章节不会。
命令启动的完整日志：

您可以看到，我已经在输入＃1（元数据文件）中编辑了标题键和第一章的名称，但输出中只有标题不同。
任何帮助均感激不尽。
答案1
已解决 - 看起来-map_metadata只在章节之前按下顶部的键，您-map_chapters还需要获取章节。
ffmpeg -i INPUT -i FFMETADATAFILE -map_metadata 1 -map_chapters 1 -codec copy OUTPUT
