• FFmpeg Batch Merge From Input Folder

  4 septembre 2022, par Parham.8

  I have this command that works perfectly fine :

  


  echo off
mkdir inputs
mkdir outputs
set "InputFolder=%~dp0inputs"
for /R "%InputFolder%" %%i in (*.mp4) do ffmpeg -i "%%i" -c copy "outputs\%%~ni.mkv"


  


  I'm trying to make this command work as well with no success :

  


  echo off
mkdir inputs
mkdir outputs
set "InputFolder=%~dp0inputs"
for /R "%InputFolder%" %%i in (*.mp4) do (ffmpeg -n -i "%%~ni.mp4" -i "%%~ni-eng.srt" -c copy -max_interleave_delta 0 -map 0 -map -0:v:1? -map -0:v:2? -map 1 -fflags +bitexact -map_metadata:g -1 -map_metadata -1 -metadata title="" -metadata comment="" -metadata:s:v title="" -metadata:s:v language="und" -metadata:s:v VENDOR_ID="" -metadata:s:a title="" -metadata:s:a:0 language="eng" -metadata:s:a:0 handler_name="English" -metadata:s:a VENDOR_ID="" -metadata:s:s:0 language="eng" "outputs\%%~ni.mkv")


  


  Any suggestions to make it work ?

  


• Looping Variables in a Batch File (for use with FFmpeg)

  16 avril 2021, par OrdinaryCarrot16

  I am creating a batch script that stores the input of the user into variables, that will later be used for creating converting files then adding metadata (via FFmpeg). It is working pretty good, now I'm just trying to figure out how to loop the FFmpeg line that uses all the variables the user inputted, and it will loop the command till it reaches the number specified in the 'track_amount' variable.

  


  Do you have any ideas on how to make this work ? Thanks !

  


  setlocal enabledelayedexpansion

:: Scan current directory for audio files
DIR *.mp3 OR *.m4a

set /P cover-art=Select the Audio/Image File with the Cover Art (ex. MP3/M4A or JPG/PNG): 
set /P artist=Artist/Band Name: 
set /P track_amount=How many tracks are in this album: 

if %track_amount% GTR 1 (
    set /P album=Album Name: 
)

set /P filename=Song File Name: 
set /P title=Song Name: 
set /P track=Track Number: 
set /P genre=Genre: 
set /P language=Language: 

ffmpeg -i "%cover-art%" -vf scale=512:512 -sws_flags bicubic cover_tmp.png

for %%t in (!track_amount!) do ffmpeg -i "%filename%" -i cover_tmp.png -map_metadata -1 -map 0:0 -map 1:0 -id3v2_version 3 -metadata artist="%artist%" -metadata album="%album%" -metadata title="%title%" -metadata track="%track%/%track_amount%" -metadata genre="%genre%" -metadata language="%language%" -c:1 png -disposition:1 attached_pic -c:a libmp3lame -ar 44100 -b:a 160k "%title%.mp3"
