mp3player broken in libogc 1.7.1a ?

[toddy]

After updating to v1.7.1a, the sound in my game has gone silent. The relevant bit of code is

Code: Select all

long BGMPlayer::lSize;
unsigned char * BGMPlayer::buffer;

void BGMPlayer::init(const string soundDir) {

	MP3Player_Init();

	string filename = soundDir + "ttbgm.mp3";
	//char * filename = (char *)"sd:/sounds/ttbgm.mp3";
	FILE *fd = fopen(filename.c_str(), "rb");

	// obtain file size:
	fseek(fd , 0 , SEEK_END);
	lSize = ftell(fd);
	rewind(fd);

	// read the file
	buffer = (unsigned char*) malloc (sizeof(unsigned char)*lSize);;
	fread (buffer, 1, lSize, fd);
	fclose(fd);
}

void BGMPlayer::process() {
	if (!MP3Player_IsPlaying()){
		MP3Player_PlayBuffer(buffer,lSize,NULL);
	}
}

with the process method being called in a loop. Full source code is available at http://www.themightystags.com/toddtris_wii/ . Reverting to v1.7.0 fixes the problem.

I assume there must have been some changes in this area as I have to link against libasnd in v1.7.1a whereas this isn't the case with 1.7.0.

There also seems to be a bit of a bug in the v1.7.0 mp3player. The last couple of seconds of the MP3 don't seem to get played for me so I have to add some silence to the end.

Any help appreciated.

Thanks,

Toddy

I'm having the same problem. I'm just learning C programming, and I was trying out the MODPlay functions, but wasn't able to hear any audio. I spent 2 days trying to figure out what I was doing wrong when I found your message regarding 'silent mp3's'.

So I downloaded the libogc 1.7.0 library, and my .MOD files play fine!!

But what I want to know, is this a bug in the libogc library, or is there a new way to initialize sound playback with libogc 1.7.1??

Thanks!!

Hi,

call ASND_Init() prior to MP3Player_Init().

Thanks for your reply! I'll give that a try when I get home from work tommorrow!

I'm pretty sure it's going to work too

Thanks again!
