给MP4添加文字不成功是什么原因?ffmpeg -i in.mp4 -vf subtitles=sub.srt mp4-srt-out.mp4

在MP4上添加文字用如下命令是否错误了?

ffmpeg -i in.mp4 -vf subtitles=sub.srt mp4-srt-out.mp4

其中sub.srt是按照格式编写的字幕文件,添加后的文件不能显示字幕文件里的文字,用的是暴风影音播放器,如果手动添加字幕文件就可以在视频里看到需要添加的文字!

看看ffmpeg的输出,是否有错误或警告信息?

另外检查下字幕格式是否正确?大部分播放器会自动加载外挂字幕,将你的字幕文件(srt,ass,ssa,sub等)命名成和视频名一样的文件名(例如视频名myvideo.mp4,则对应的字幕名应为myvideo.ass,其他格式字幕也是如此,放同一个目录下),然后用播放器看看(比如kmp, mplayer, vlc,potplayer等等,甚至装了vobsub的wmp也可以),是否有外挂字幕?

如果预览是没问题的,那么理论上用ffmpeg转码压制也不会有问题,如果预览都有问题的话,那么就不用往下走了

我试过了改为字幕和视频文件名一样后,预览是没问题,视频上是有外挂字幕的

我这边试了下,一切正常,没有你的那个报错。我的测试环境是ubuntu 14.04, ffmpeg使用ppa仓库中编译好的,应该是指定了默认字体。srt字幕似乎没有字体信息,所以ffmpeg会默认一个,应该是你用的版本默认参数编译有问题,你自己去搜一下,应该是可以指定默认字体的,配置ffmpeg参数加一个中文字体应该就好了。

我的srt样本:


1
00:00:00,000 --> 00:00:00,000

2
00:00:02,180 --> 00:00:10,810

7
00:00:38,290 --> 00:00:45,340
声声枝头雀 笑唱悲伤空对月

8

不知心向 何谓所悦

14
00:01:31,630 --> 00:01:38,120
盼相逢无需悲切 绵绵相思不绝
