删除视频的音频流 - 递归地使用 FFMPEG 转换音频或视频

取消注释您希望使用的行和文件类型。您可以添加更多“预设/标志”，这只是一个想法。

sudo nano /media/audio.sh

---用于递归转换视频剥离音频流而不转换任何内容的脚本！

#Uncomment a Preset FLAGS depending on video/subtitle/audio stream wanting to keep, easy to find which stream via playing in VLC and hitting CTRL + J (when not in fullscreen)

#TO ADD SUBTITLES< THEY MUST BE SAME NAME AS FILE*Check out Filebot Filerenamer*
#Don't Strip audio and do subtitles at the same time, do one at a time
#To add subtitles, just uncomment the line under ADD SUBTITLES

#TO FIX AUDIO SYNC
#Use hotkeys J/K in VLC to find correct value
#DONT use FLAGS, just OFFSET 

#FLAGS DESC:
#"-map 0:0 -vcodec copy" -- which video stream to copy
#"-map 0:1 -acodec copy" -- which audio stream to copy
#"-map 0:2 -scodec copy" -- which subtitle stream to copy
#"-itsoffset 0.2"        -- DELAY Audio by 0.2 seconds can do -0.2 for opposite effect!

###Video Stream 0 Audio stream 1 Subtitle Stream 2
#export FLAGS="-map 0:0 -vcodec copy -map 0:1 -acodec copy -map 0:2 -scodec copy"

###Video Stream 0 Audio Stream 1
#export FLAGS="-map 0:0 -vcodec copy -map 0:1 -acodec copy"

###Audio Stream 2
#export FLAGS="-map 0:0 -vcodec copy -map 0:2 -acodec copy"

###Audio Stream 3

    ##To remove source files after conversion and rename back to original w/o *FINAL*, uncomment second line #&&find (Must become 1 line of code IE: Hit delete 2 times)
    ##I do not reccomend using this unless you are 100% of what you are doing, it will delete source files even if conversion fails, basically unless you are creator of files
    ##ANY files without FINAL will be deleted, be warned, I have personally deleted many a files I didnt want to by using this line :P
