Combine Sequential MP4 Files After Download

[SkydiverFL]

How can I combine hundreds of sequentially named MP4 files after they are downloaded? The training course I am downloading is divided into "chapters" and "segments". I need to have one single MP4 file so I may load it into iTunes or Plex.

I have a "CONCAT.BAT":

Code: Select all

@ECHO OFF

ECHO  CONCATenate all the parts of a multiple movie into one
ECHO  "specs" should be the same, files listed in the correct order, 1 to X...
ECHO  therube 01/23/2015
ECHO.
ECHO  %*
ECHO.
pause


SET     OUT=C:\OUT
ECHO    OUT=: %OUT%
SET   OFILE=%OUT%\%~n1_CONCAT%~x1
ECHO  Output filename: "%OFILE%"
ECHO. > %OUT%\CONCAT1.TXT
PAUSE


echo FOR: 
PAUSE


for %%i in (%*) do echo %%~i >> %OUT%\CONCAT1.TXT
cat         %OUT%\CONCAT1.TXT
PAUSE

sed -f %OUT%\sed_go1 < %OUT%\CONCAT1.TXT > %OUT%\CONCAT2.TXT
cat         %OUT%\CONCAT2.TXT
PAUSE

sed -f %OUT%\sed_go2 < %OUT%\CONCAT2.TXT > %OUT%\CONCAT3.TXT
cat         %OUT%\CONCAT3.TXT
PAUSE


ffmpeg -f concat -i %OUT%\CONCAT3.TXT -c copy "%OFILE%"
PAUSE
EXIT

sed is used to clean up the inputs to get things into an order that ffmpeg will like.
[the actual contents {"commands"} for sed will have to wait till i get access to them]


More generally:

FFmpeg wiki: Concatenate

And the missing sed's:


sed_go1:

Code: Select all

s/\"/'/g
s/^\s*//
s/\s*$//
s/^\s*'//
s/'\s*$//
s/' '/\n/g
s/' /'\n/g
/^\s*$/d

sed_go2

Code: Select all

s/^/file '/
s/$/'/

(All they do is to format the list of file names in a manner that FFmpeg will like.)

[I would typically select the source files using either Everything or my file manager, Salamander, & "Send to... -> CONCAT" from there.]
