Title: Using SOUND and FONT files w/ Ubuntu?
Post by: SirCrow on May 30, 2018, 10:17:37 pm
I can't access [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there], so...

Please tell me how I can get my prog. to play .mp3 or other sound files under Ubuntu.
Also, can FONTs be used w/ Ubuntu/Linux?  Thanks.

Joe

Ubuntu works just fine with sound and fonts.

Code: QB64: [Select]
  1. SCREEN _NEWIMAGE(500, 300, 32)
  2.  
  3. f& = _LOADFONT("/usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf", 42)
  4. IF f& THEN _FONT f&
  5.  
  6. 'Music from [youtube]https://www.youtube.com/audiolibrary[/youtube]/music
  7. 'Mr. Tea by Rondo Brothers
  8. PRINT "Loading music..."
  9. m& = _SNDOPEN("Mr_Tea.mp3")
  11.  
  13.     CLS
  14.     x = RND * (_WIDTH / 3)
  15.     y = RND * _HEIGHT
  16.     COLOR _RGB32(RND * 255, RND * 255, RND * 255), _RGB32(RND * 100, RND * 100, RND * 100)
  17.     _PRINTSTRING (x, y), "Hello, Ubuntu!"
  18.     _DISPLAY
  19.     _LIMIT 5
  21.  
  23.  

The code above compiled and ran fine on my Ubuntu 16.04 virtual machine running QB64 1.2 (development build from www.qb64.org). I've attached the mp3 file I used as well as the binary that was generated. The ttf font I used is supposed to come by default with Ubuntu.

Please share the version you're using (both Ubuntu and QB64) as well as the files you had trouble loading.

IDE ver. is 1.2 -- but development or not, I don't remember
Ubuntu ver. is 18. ... something....how do I check it?  Did it once, forgot how.  Terminal, no doubt.  Hate that terminal.

As far as sound files, do I need to change all \ to / in the paths?
One line in my prog. looks like this:
 Snd.Name& = _SNDOPEN("SB_Sounds\J_Pop_002.mp3", "VOL")

Any parameter to _SNDOPEN that's not the file name has been deprecated, so you can drop "VOL" for good (and still be able to use _SNDVOL later on).

One thing to consider in Linux is that file names are case sensitive. Either \ / should make no difference as QB64 usually caters for that on its own, but you're on a / system, so why not go with it, right?

Check that Snd.Name& contains a value > 0 and then hit _SNDPLAY Snd.Name&, you should be good.

Did you run my sample?

Thanks.  Just ran your sample and, with the  _SNDOPEN line active, I get this:

Code: QB64: [Select]
  1. libqb/os/lnx/libqb_1_2_111100000000.o: In function `snd_decode_mp3(unsigned char*, int)':
  2. libqb.cpp:(.text+0x67a77): undefined reference to `mp3_create'
  3. libqb.cpp:(.text+0x67aaf): undefined reference to `mp3_decode'
  4. collect2: error: ld returned 1 exit status
  5.  

Without that line, it runs fine.  The .mp3 is there in the same folder as the sample source, so....?

Did you run my binary? (compiled on a 64bit Ubuntu - if yours is 32bit you won't be able to anyway)

I believe I did, and I believe it is -- but I'll look into it further.
Thanks!
