Which AAC encoders support simultaneous encoding?
I've just moved up from a P4 HT to a brand spanking-new Core i7. I'm quite impressed with how much faster it is with encoding, especially when I'm running on three cores at once.
However, while x264 will happily encode on three cores at once, NeroAacEnc won't--the resulting AAC files are trash, either no audio or static. Is this a problem with how MeGUI invokes NeroAacEnc, or with the latter's own behavior? Is there a multiple-invocation-safe AAC encoder supported by MeGUI? Thanks for any information you can provide! MeGUI: 0.3.1.1051 NeroAacEnc: 1.3.3.0

I tried and didn't come up with any useful results.

the way I read that linked thread is that it's a frontend that allows for parallel encoding of separate files - the same can be achieved using worker threads in megui.
and the output has probably something to do with filters.. it's one of the most common problems with megui (not that it's megui's fault though.. )

Maybe something in the AviSynth script that MeGUI assembles isn't threadsafe... That would suck.

(No, DirectShowSource isn't one for me, since that... well, it either takes forever or it just locks up at "Preprocessing" with no useful log entries to debug. Hard to tell.)

Megui's preprocessing takes a while (with no progress bar), but it gets there in the end. Are you sure it's locking up?

I let it preprocess for a half-hour, which is about five times as long as it takes to do a complete file (preprocess and process) without "Force DirectShow" checked. That sure looks like a hangup to me...
