problems trying to get music to play

[ttlanhil]

I've been trying to get the client to play the .oggs. it's trying not to.

I know the .dlls are new enough because I downloaded the latest release earlier today, and no help

it all works up until trying to ov_open the .ogg itself, then I get a memory access error. if the file isn't openable, then all is well

 

the ov_open call is in sound.c:209

 

 

backtrace:

the offending part of the fseek() is:

_lock_str(stream);

stream is as such:

stream	0x00565578 {_ptr=0x1c2dae10 "OggS" _cnt=0x00000000 _base=0x1c2dae10 "OggS" ...}	_iobuf *
_ptr	0x1c2dae10 "OggS"	char *
_cnt	0x00000000	int
_base	0x1c2dae10 "OggS"	char *
_flag	0x00002009	int
_file	0x0000000a	int
_charbuf	0x00000000	int
_bufsiz	0x00000200	int
_tmpfname	0x00000000 <Bad Ptr>	char *

(that "OggS" is what the start of the file looks like, with a null at the end, so it's proof the file is opened)

 

and the memory that cannot be accessed is always 0x10, which is odd...

 

I don't really read assembly, but in case anyone does and it helps; the line that the error comes up on in ntdll is last of the following:

7C918FDA  mov		 eax,dword ptr [esi+10h] 
7C918FDD  cmp		 eax,ebx 
7C918FDF  mov		 dword ptr [ebp-4],eax 
7C918FE2  je		  RtlpUnWaitCriticalSection+2Fh (7C919086h) 
7C918FE8  mov		 eax,dword ptr [esi] 
7C918FEA  inc		 dword ptr [eax+10h] 

(at time of crash, eax is 0, esi is 5658008. which seems wrong after the mov)

 

now, I have one possible culprit, that's that using .dll's makes passing the file handle not work. but the EL client that's available for download has them as .dlls too.

I've tried a static link, but it comes up with missing references in the .lib, not sure if I did it wrong, or i need to statically link more stuff in, or what

 

any constructive comments welcome
