ffmpeg：“未找到引用的 QT 章节轨道”

Using ffmpeg将 QuickTime 中的音频替换为 WAV 中的音频。

谁知道我为什么会这样Referenced QT chapter track not found?

Command:

$ ffmpeg \ -i "$video" -t 25 \ -i "$audio" -map 0:v -c:v copy -map 1:a -c:a pcm_s24le -ar 48000 \ -hide_banner "$output"

Output:

同样的错误与-map 0:v:0

输出看起来创建时没有错误。

该错误的含义是 MOV 标头指示存在带有章节标题和时间戳的文本轨道，但 FFmpeg 实际上无法在文件中找到该轨道。

Adding -ignore_chapters 1 before -i "$video"将阻止 ffmpeg 寻找该轨道。
