Re: [pygame] How to play a sound from a "file" of infinite size?

[Tomasz Primke <tprimke@xxxxxxxxxx>]

First: the file format, that the C library decodes, requires a lot of 
processing - therefore the idea to make samples in pure C and then to wrap 
it all with Python (e.g. with Pyrex) sounds... reasonable. But it will be 
the last resort. My philosophy of programming is to use Python as long, as 
it's fast enough; then use Pyrex as long, as it's fast enough; and as the 
last resort, use C.

This single "streaming" channel looks realy interesting. And use of the 
SDL_mixer library would be very portable solution (I like it!). But 
wouldn't that collide with the PyGame? I need PyGame to make this player 
look nice.
