[MPlayer-dev-eng] Best method to communicate 2 process w/ sync

[Gustavo Sverzut Barbieri]

Hello,

I'm writting an audio filter to new Mplayer system. It's function is
analyse the data and output it to other programs.

By now I'm using FIFO, but to get sync, I need to set it blocking. The
problem is that until anything read the FIFO, Mplayers got blocked, no
sound, no video. 

I want to make it a way that sotwares could start/stop to read any
time, without blocking Mplayer.

I've looked ad MMap, not tested, but I think it will desync.

Anyone could please point me some directions?


Gustavo
