[Scummvm-devel] Streaming sounds in Scumm games

[Johannes Schickel]

Hi again,

I did take a short look into the VOC code. It seams the transition 
should be pretty straight forwarded. One could adapt the "makeVOCStream" 
factory to match the ones for MP3, OGG/Vorbis and FLAC along with it 
too. (That's an old TODO from our TODO page), this would then ease to 
make it clear, that the code will take over the "stream" object.

However there seems to be some little problem, which might require some 
more tinkering. The SAGA engine does use the "loadVOCFromStream" method, 
which does load the whole VOC file into memory and just returns a 
pointer to the sample data. I'm not familiar with the SAGA code, so one 
of its developers might want to comment on why it does that and whether 
it could be easily changed. After all it supports MP3 etc. compression 
of the audio files too, so I would guess it shouldn't be too hard to 
adapt the VOC playback to allow proper streaming of VOC files too.
