AW: AW: [SDL] Short question: is an ogg-file streamed by sdl_mixer or first loaded completely into memory?

[Andre Krause]

Ok, i watched my memory-counter: you are right - the ogg file is first
decompressed and goes uncompressed into memory :-(

Hopefully sometimes RWOps functionality is implemented for ogg-file -
streaming...
Or is it principally impossible?

Are you really sure ? I did not notice my program eating up 20 mbytes
more mem (that would be the size of the uncompressed ogg) i think the
ogg is loaded as it is and ogg-lib can play from a memory handle. But i
will check this again and watching my memory stats while my pgro loads !

Music is streaming (when possible), sfx are not. I.e load a Ogg as a
sound effect and it's decompressed into memory at load time. If you use
good sound quality and a long song (or worse, more than one song loaded
at once) this can quickly eat up A LOT of memory.

Music on the other hand is read/decoded as needed (other than in obvious
cases when this isn't possible, such as for mods). Currently you have to
give SDL an actual file for this, as noted.
