It looks like ov_pcm_total can get the number of pcm sample frames (multiplied
by 2*channels for the number of bytes). Though, I assume this would only work
on seekable complete files, which isn't necessarily guaranteed to be true if
it's user-replaceable. Non-seekable files would likely return 0 or negative
for the size, so you would need to do the method I described earlier for them.
