[MPlayer-users] mplayer and alsa9/dmix

[joy ping]

i guess he doesn't do further research, cause currently i see no way to 
implement working dmix-plug with existing alsa9-module of mplayer.
the problem is by design of the alsa9-module of mplayer. it uses a kind 
push-algo but dmix-plug requieres a poll function. maybe someone writes a 
alsa9-poll-module but that will something like a workaround of the of the 
intended mplayer architecture, cause current mplayer (with alsa9) works in 
the following way:
(very simple scheme)
read audio-data --> push to buffer of soundcard -->if space left in buffer
	|						|
	-------------------------------------------------

so you have to introduce another buffer in the alsa-module and let the 
driver poll from it. i think something like this is already implemented in 
ao_sdl or arts?
but not at least, timing of mplayer depends in a way on the soundlayer, 
what will not make the whole thing easyer.
i think, instead of fuzzling around with alsa-dmix a better aproach would 
be to write an ao_jack which can do all things like dmix and more.
