Simulator crashes on media.playSound()
Posted on Tue, 2010-02-02 02:38
Hello!
I just tried to "simulate" a program which uses "media.playSound" in order to play an MP3 file - but the simulator always crashes because it can't find that file. The code is simple:
media.playSound(system.pathForFile("Zarathustra.mp3",system.ResourceDirectory));
and -surprisingly (or not) - the error message displayed by the "Terminal" version of the simulator shows exactly the same (full) path to the file as (another) terminal into which I dragged the file itself. Thus, the file path looks correct as well...and it's present...and iTunes can play it.
Thus, I don't know how to proceed :-(
Additionaly, it's quite annoying having to restart the simulator over and over again just because it can't find a single resource file!
For your records, here is the crash report

Hmmm...
I also tried with other MP3 files - but can't convince the simulator/device to play ANY of them
I also added artifical event handlers for "enterFrame" in order to keep the application running in any case - but that did not help either.
Any ideas?
Thanks in advance for any help!

Oh,
I just realized that the code samples shipped with Corona do not work on the simulator either!
It therefore seems to be a bigger problem...sigh!

Oops,
it seems as if the simulator does not find ANY documents or resources (not even PNG files) on my machine!
That's bad!

Well,
I am now able to load images - by avoiding the system.pathForFile call! It seems as if Corona does not support directories yet!
Thus: always use file names directly! Do not use "system.pathForFile"!
Needless to mention, that playSound isalso working now!
Kind regards,

Did it fix your media.playSound() problem as well?

Walt,
yes - I did (as mentioned in the "needless to mention" phrase)
Nevertheless, playSound should NOT crash when the sound file does not exist: when a null Image object is created, an internal assertion fails (which is still somewhat cryptic, but - by scrolling back - the actual reason for this failure can be seen in clear text).
For that reason, the bug report is still meaningful!
Kind regards,
Andreas Rozek

Oops, right you are; my apologies, trying to do too many things too early in the morning.
Agreed, not finding a file should not cause a crash.

Walt,
don't worry - I make such mistakes throughout the whole day, not just early in the morning ;-)
Let's hope, that the Ansca staff is fixing that bug soon (should not be too complicated)
Kind regards,
Andreas Rozek

I'm new to this and am having the same trouble, what is the alternative to system.pathForFile?
Cheers

the sound file should be in the same root directory of your .lua
calling playSound("filename") or eventSound(filename) should work unless you are doing something else.

I don't get any sound from the simulator at all. I've tried all the sample files that include sound. No errors
in the terminal. The demo apps work correctly apart from not playing sound.

For the record, there was a bug where if the sound file was missing, the simulator would crash. This has been fixed (in the latest beta). I can build the Zarathustra hello world and it plays sound just fine, in the simulator and on device. So additional info or specifics would be most welcome.
Hello again!
I just tried to build the app for my device and run it there:
Too bad...
