[vorbis-dev] Couple more problems (ov_open_callbacks)

[Brian Hook]

I'm in the final throes of debugging (hopefully) and the last thing I'm
trying to do is figure out why I'm getting static instead of usable
data.  I have a verified Ogg file (it plays fine in WMA); I've visibly
inspected the info struct and it matches my output format; I've verified
my audio playback code by using a generated sine wave (sounds correct).

So that leads to a problem with how I'm using ov_read().  I've modeled
my code around the sample code, and I check my error returns fairly
religiously.  The only weird thing I'm doing is using
ov_open_callbacks().  My callback routines simply read data out of an
in-memory bit bucket, so there's not much code there, e.g. my read
function is basically:

memcpy(pDst, myStreamPtr, bytes );
myStreamPtr += bytes;

..etc. etc.  I didn't bother implementing a close function (I just
stubbed it out).

Looking at my read callback, I always seem to get requests for one
object of varying size.  I've modeled my callbacks on the stream IO CRTL
stuff (fseek/fread/ftell/fclose), including parameters and return
values.  I assume this is correct?

Any other obvious problems I should look for?  Barring any epiphanies, I
may end up having to implement a test version using ov_open to see if
it's my callbacks (which I suspect).

Thanks,

Brian
