@Nev
going through the database for .mov i experienced something odd with Lav Audio ?
@ Decoding PCM sowt Lav Audio showed considerably higher CPU utilization then compared to the MPC-HC Audio Decoder also tried to disable 32 bit floating point and also 32 bit in general and enabled same for MPC-HC Audio no difference (was rendering with the default 16 for both from the start)
i wonder where that difference of Lav Audio = 5%, MPC-HC Audio = 2% (3% Utilization difference) comes from in this decoding case ?

AAC Decoding doesn't show such a huge difference
