I'll definitely be trying this. But new questions come to mind : * This means re-encoding *everything* to AC3 on the fly? 2.0 music too? * What kind of CPU usage is to be expected for a typical 5.1 signal? * What about other formats like DTS? (please forgive my ignorance) It seems pretty obvious to me that if my amplifier is able to accept the raw stream already contained in my movie files, then sending it as-is is the optimal and theoretically not-so-hard solution, which many video players already implement. So this last question to the Moovida developers : How hard will it be to switch to using playbin2/decodebin2 and doing the right thing for streams that can be decoded by Hi-Fi amplifiers?
