Use FFmpeg to process a tree of MKV files

[Styreman]

Hello all,

I'm very new to the batch code scene and have been familiarizing myself lately will all the commands. I've been struggling to create a batch code which does the following:

Scans folder for any *.mkv files (will only be 1 in folder)
Takes file location and file name
inputs this command (replacing FILENAME with name from file): ffmpeg -i FILELOCATION\FILENAME.mkv -c:v copy -c:a copy FILENAME.mp4
renames FILENAME.mp4 to FILENAME.avi

It's basically a rewrite of this code, but in DOS (mines using ffmpeg instead of avconv)

#!/bin/bash
#avconv --help
IFS=$'\n'
clear
for filename in *.mkv
do
echo "$filename"
newfilename="${filename%.mkv}.mp4"
echo "${newfilename}"
avconv -i $filename -vcodec copy -acodec copy $newfilename
done

Any help would be greatly appreciated!!

Test this. It should create the AVI file in the same folder as the MKV folder.

Code: Select all

@echo off
for /r "c:\base\folder" %%a in (*.mkv) do (
   ffmpeg -i "%%a" -c:v copy -c:a copy "%%~dpa\%%~na.avi"
)

Works great!

Care to explain what this command is doing? %%~dpa\%%~na.avi

Thanks for the quick reply, I really appreciate it

Care to explain what this command is doing? %%~dpa\%%~na.avi

issue /? on for

Code: Select all

>for /?

Code: Select all

% ~ dI - expands% I to a drive letter
% ~ pI - expands% I to a path
% ~ nI - expands% I to a file name

you used `a` as token, so %%~dpa expands `a` to a drive and path
