➜  ffmpeg_edit_subtitle
出错:
[AVFilterGraph @ 0x7fa224608740] No such filter: ‘ass’
-》之前也遇到类似错误:
[AVFilterGraph @ 0x7fc399d0a980] No such filter: ‘subtitles’
-》看来mp4,即没有subtitles,也有没ass的filter
再去试试
-vf ass=subtitles.ass
-》看到人说了:
Use the libass library (make sure your ffmpeg install has the library in the configuration –enable-libass).
-》发现和上面的错误是一个意思
-》不过,从之前的ffmpeg的输出看,此处的ffmpeg没有:enable-libass
所以现在是:
已经用了:
ffmpeg -i CTT_Folge_01_CH_Subs_DefaultZhcnButNotShow.mp4 -i subtitle.srt -c copy -c:s mov_text movTextSubtitle.mp4
把srt的字幕 添加到mp4了
-》但是还是只是subtitle stream,而不是burned in=embed=嵌入
-》想要嵌入,则需要用:
-vf ass=subtitles.ass
但是此处没有ass的filter
-》需要去想办法给ffmpeg添加enable-libass

Updating Homebrew...
Warning: ffmpeg 3.4.2 is already installed and up-to-date
To reinstall 3.4.2, run `brew reinstall ffmpeg
需要重新安装ffmpeg。
那就重新安装,加上那些参数,结果:
【已解决】Mac中brew reinstall ffmpeg出错:Error: Calling keg_only :provided_pre_mountain_lion is disabled! There is no replacement
然后就支持了ass。
