FFMPEG - 将MKV转换为包含所有流（字幕）和水印的MP4

Question

我花了几个小时进行研究，仍然有问题... 我想将.mkv文件转换为带有水印和字幕（来自mkv）的.mp4。

我尝试了几个命令，但总是错误或成功与水印没有字幕。 下面是一些命令我试过了（不是全部）：

部分成功 - 一些文件被转换字幕，但我有153个文件被转换无字幕......（无论是从.MKV到.MP4）：

ffmpeg -i 025.mkv -vf "movie=logovideo2.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10,subtitles=025.mkv [out]" 25.mp4 

ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0,subtitles=001.mkv[out]" -map "[out]" -map 0:a -c:s ass 001.mp4 

故障 - 命令与错误：

ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0[out]" -map "[out]" -map 0:a -map 0:s -c:s ass 001.mp4

Answer 1

命令ffmpeg -i 001.mkv -i logovideo2.png -filter_complex "[0:v][1:v]overlay=0:0,subtitles=001.mkv[out]" -map "[out]" -map 0:a 001.mp4
