windows批处理.bat自动.m3u播放列表创建/更新 [英] windows batch .bat automatic .m3u playlist creation / update

问题描述

每当我在我的电脑和/或智能手机上添加新文件时，我就需要手动更新我的庞大的mp3 / mp4数据库
所以我寻找一些帮助创建一个批处理文件创建/更新我的所有

需要两个批处理文件（第一个调用第二个）：

---

第一个很容易，我几乎得到了; - ）

create_all_playlist.bat（不需要参数，自定义文件） / p>

  create_m3u.bat misc-70-80.m3u misc\70 \ misc\80\ 
 create_m3u .bat misc-70-80-90.m3u misc\70\ misc\80\ misc\90\ 
 create_m3u.bat misc-60-70-2000-2010.m3u misc\ 60 \ misc\70\ misc\2000\ misc\2010\ 
 [...] 
 create_m3u.bat albums-2010.m3u albums\2010\ 
  

很容易吗？

我需要你的帮助来写第二个.bat，动态的：

create_m3u.bat output-playlist- name.m3u folder-1 folder-2 [...] folder-n

应该看起来像这样（注意所有都是相对路径和搜索* .mp3 * .mp4 * .ogg（无论类型我cutomize /硬代码）将是递归进入指定的文件夹）

（原始.m3u兼容大多数android& PC播放器）

  misc\2000s\Kelly Rowland  -  Work（Freemasons Arabic Mix）.mp3 
 misc\\ \\ 2000s \Keri Hilson  -  Knock You Down k Kanye West and Ne-Yo.mp3 
 misc\2000s\Kid Cudi vs Crookers  -  Day n Nite.mp3 
 misc\2000s\Korn -  Inja.mp3 
 [...] 
 misc\2000s\Ladyhawke  -  My Delirium.mp3 
  

---

在最好的情况下，只有最好的情况下，让我们说如果有人有足够的技能生产完整的mp3 / mp4 TAG阅读和形成如下

 ＃EXTM3U 
 #EXTINF：227，A-Ha  -  Take On Me 
 misc\80s\\ \\ A-Ha  -  Take On Me.mp3 
 #EXTINF：257，ACDC  - 回到黑色
 misc\80s\ACDC  - 回到Black.mp3 
 #EXTINF：311， Aerosmith&运行Dmc  - 走这条路
 misc\80s\Aerosmith& Run Dmc  -  Walk This Way.mp3 
 [...] 
 #EXTINF：289，Alannah Myles  -  Black Velvet 
 misc\80s\Alannah Myles  -  Black Velvet.mp3 
  
 
 
 
 
 
 
并感谢!!

tired of manually updating my huge mp3/mp4 DB each time i add new files on my computer and/or smartphone, 
so i'm looking for some help to create a batch file that create/update all my playlists .m3u automatically.

2 batch files are required (1st is calling the 2nd) :



1st one is easy, i've almost got it ;-)

create_all_playlist.bat (no arguments required, customized file)
create_m3u.bat  misc-70-80.m3u            misc\70\ misc\80\
create_m3u.bat  misc-70-80-90.m3u         misc\70\ misc\80\ misc\90\
create_m3u.bat  misc-60-70-2000-2010.m3u  misc\60\ misc\70\ misc\2000\ misc\2010\
[...]
create_m3u.bat  albums-2010.m3u           albums\2010\
pretty easy huh?



I need your help to write the 2nd .bat, the dynamic one :   

create_m3u.bat output-playlist-name.m3u folder-1 folder-2 [...] folder-n 

to play it easy, the output file.m3u should looks like this (note all are relative path and the search for *.mp3 *.mp4 *.ogg (whatever type i cutomize/hard-code) would be recursive into the designated folder)

(raw .m3u compatible with most android & PC player)
misc\2000s\Kelly Rowland - Work (Freemasons Arabic Mix).mp3
misc\2000s\Keri Hilson - Knock You Down ft Kanye West and Ne-Yo.mp3
misc\2000s\Kid Cudi vs Crookers - Day n Nite.mp3
misc\2000s\Korn - Inja.mp3
[...]
misc\2000s\Ladyhawke - My Delirium.mp3




At very best, only for the very best, let's say if someone is skilled enough to produce the full mp3/mp4 TAG reading and formating as following
#EXTM3U
#EXTINF:227,A-Ha - Take On Me
misc\80s\A-Ha - Take On Me.mp3
#EXTINF:257,ACDC - Back in Black
misc\80s\ACDC - Back in Black.mp3
#EXTINF:311,Aerosmith & Run Dmc - Walk This Way
misc\80s\Aerosmith & Run Dmc - Walk This Way.mp3
[...]
#EXTINF:289,Alannah Myles - Black Velvet
misc\80s\Alannah Myles - Black Velvet.mp3




and thanks!!

for the raw m3u, beers are on me :-)

for the extended full m3u : beers and i'll cook the duck magret  ;-)

I used c:\sourcedir as my starting directory. No parameter-validity checks are performed. You'd need to CALL create_m3u.bat from create_all_playlist.bat because the target executble is a batch file.

As for the missing data - hardest part is extracting information....
