Title: Mini MP3 Player
Post by: SierraKen on August 21, 2019, 05:52:12 pm

Today I decided to try my hands on a mini mp3 player. I tried to see if I can make it play a whole folder but I'm not sure how to do that. I tried SHELL with SORT to make a temp .txt file of the directory. But I would have to figure out how to read that file 1 song at a time. I might try that more another time. But for now, I made this little player that plays 1 song at a time. It also can change directories. It has nothing except play. No stop, FF, rewind, pause, or anything. LOL But it could be used for something to quickly play a song or added to another game or program for a song. I'm sure many people have made stuff like this in the past, but it's my first one. :)

Hi Ken. Try this example, for more clearity see also to created file MyFiles.txt.
Run this in folder with some MP3 sound files.

Code: QB64: [Select]

1. REDIM file(0) AS STRING 'create empty text array. 0 is record nr. 1!
2. SHELL "dir *.mp3 /B > MyFiles.txt" 'create mp3 files list to file MyFiles.txt
3.  
4. 'now - load this files. I show you how do it.
5. 'first for you program show for you files, which are found in current directory:
6.  
7. OPEN "MyFiles.txt" FOR INPUT AS #1
8. WHILE NOT EOF(1)
9.     LINE INPUT #1, file$
10.     PRINT file$; " is record nr."; record; "in file. I add it also to array 'file' also with this number" 'you see which MP3 file is on which position in file list MyFiles.txt
11.     PRINT "press any key"
12.     SLEEP
13.     file(record) = file$ 'so we add to record 0 first file, because variable record here is zero
14.     record = record + 1 'for next loop we needed array higher up to one
15.     REDIM _PRESERVE file(record) AS STRING 'this do array bigger without deleting content
16. WEND
17.  
18. 'so now file(0) is first file from disk. file(3) is 4th file from disk. Try it:
19. ready:
20. PRINT "Input music file for playing (maximal value is"; UBOUND(file) -1; ")"
21. INPUT rec
22. IF rec > UBOUND(file) -1 OR rec < LBOUND(rec) THEN PRINT "Invalid record number!": GOTO ready
23. _SNDPLAYFILE (file(rec)) 'run REC nr. record
24.  

I'm one of those who wrote own player. It was posted on the old [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there] forum. The source code is still with me if you are interested. It is 63 kilobits of source code. There was a problem with sound file names that were written with unicode characters.


Then, if you need control, if some music is now played or not, use function _SNDPLAYING for it.

If you need using all sound files in one step, use DIR *.* /B > filelist.txt. Then open this file and read last 4 characters (RIGHT$). If this are .MP3 or .WAV or .OGG, write this files to array as in my example. Is possible also playing .MID files if you use external library.

Thanks Petr, I understand a lot of what you did there and put it in my program. I'm going to see if I can find a way to play the whole folder though without having to type any numbers. Or maybe make it have random play on that folder. There's probably a command that says when a song is over, I will look into that. Thanks again!

Thanks to Petr's help, I was able to finish this player tonight. :) It doesn't have all the bells and whistles, but it does say the Position of the song while playing (using INT to not show so many numbers flying by LOL). You also can skip to the next song in the folder while it's playing the whole folder. The menu lets you play just 1 song or a whole directory. It also lets you change the directory to whatever you want. Although I don't suggest trying to change to the Windows 10 built-in Music folder. I know QB64 has code for that somewhere I think, but I didn't add it because I don't use that directory. If it's pretty simple I might look into it later. But please check this out. You have to know the directory name to change to, it's just 1 INPUT line that asks for the directory name. Like I said above, this is my first mp3 player I ever made. Thank you to QB64 for letting us make these.

I added the length of the song to compare it with the position, and also the sound rate. Plus I made it faster to switch folders by using Wiki code to automatically display what folder you are on, on the front menu page. When you change folders, you don't have to press Enter again, it just goes straight back to the Menu and shows the new folder. :) This is a pretty fun program to play with. Of course I don't need this program (I use Foobar2000 to play my music), but it feels nice to know that I finally made something that plays songs.

Hi Ken,

Glad you cleared all the comments in changedDirectory GOSUB.

When I tested code, I could not read the files names that had squiggles in middle, so I don't know what to type.

We could set up the code to use same array display for files as we did for Directories so you just find the directory then press f to select file from it, no typing out file name needed, the code is in the best answer for Tiny Navigator!

I was shocked to learn your mouse scroll wheel was not working!

That sounds great! Would be awesome to add the file scrolling as well.
Yeah, as I say in the other thread, the wheel does work, just differently than what I'm used to. Sorry about that.

I do see one problem with the wheel, I'll put it in the other thread.
