Read Output in Batch
29 septembre 2016, par arielbejeI am using this code to try and download a video+subtitles using youtube-dl and then combine them using ffmpeg.
I am trying to set the video/subtitle output to title.extension instead of the regular title id.extesion, but to do that youtube-dl has a command that outputs it like an echo command, so I need to read it.
@echo off
echo Write a link and press enter
set /p link=
cls
youtube-dl.exe -u myusername -p mypassword --skip-download --sub-lang enUS --sub-format "ass" --output "%(uploader)s%(title)s.%(ext)s" "%link%"
youtube-dl.exe -u myusername -p mypassword -f worst --ffmpeg-location "%cd%\ffmpeg.exe" --hls-prefer-ffmpeg --console-title --output "%(uploader)s%(title)s.%(ext)s" "%link%"
youtube-dl.exe -u myusername -p mypassword --skip-download --get-title "%link%" > title.txt
for /f "delims=" %%x in (title.txt) do set title=%%x
ffmpeg.exe -i "%cd%\%title%.flv" -vf "ass=%cd%\%title%.ass" "%cd%\%title%.mkv"
