【中文标题】如何使用 ffmpeg 将字幕嵌入到 .mp4 电影【英文标题】：How to embed subtitles to .mp4 movie using ffmpeg 【发布时间】：2015-05-04 21:05:54 【问题描述】：

我正在尝试将我写的字幕嵌入到我创建的电影中。我正在使用 FFmpeg 版本：ffmpeg-20150418-git-edbb9b5-win64-static 和命令：

ffmpeg -i in.mp4 -f srt -i subs.srt -c:v copy -c:a copy -c:s mov_text out.mp4

我看到here。

但我在处理过程中遇到错误，当处理完成时，会有一个输出文件out.mp4 没有嵌入字幕。当我在某些播放器中播放in.mp4 时，例如media player classic 与字幕分开，字幕是同步的，一切都很好。

字幕是subrip 编码为UTF8。

我试图找出这些错误，但没有发现任何有用的东西。这似乎很荒谬。我做错了什么？

错误如：

[mp4 @ 00000000003fe020] Codec for stream 0 does not use global headers but container format requires global headers
[mp4 @ 00000000003fe020] Codec for stream 1 does not use global headers but container format requires global headers
[mp4 @ 00000000003fe020] Application provided duration: -8 / timestamp: 72205 is out of range for mov/mp4 format
[mp4 @ 00000000003fe020] pts has no value

【问题讨论】：

trac.ffmpeg.org/wiki/HowToBurnSubtitlesIntoVideo 你可能会感兴趣...对不起，我没有尝试过。 ffmpeg -i in.mp4 -vf subtitles=subs.srt out.mp4 对我不起作用.. 也可以与 -c:s mov_text 结合使用 【参考方案1】：

我刚刚遇到了类似的错误。原来我的 SRT 文件有一个虚假的字幕：

212
00:16:00,042 --> 00:15:57,581
Kim ?

基本上，这表明字幕在开始之前就结束了，这在定时文本中是不允许的，这是 mov_text 编解码器使用的基础格式。如果您有重叠的字幕，您也可能会遇到类似的错误，因为定时文本也不允许这样做。

不幸的是，我不知道有什么工具可以自动解决这个问题，所以你需要进入你的 srt 文件并手动清理它们。

【讨论】：

我使用字幕编辑（访问 www.nikse.dk 获取最新版本）这将为您完成所有这些检查并修复常见问题。
