Thanks for your suggestion. The pipeline I used wasn't made by me -- it's the
default Sound Juicer pipeline for AAC output, at least in the distro I use
I tested as per your suggestion with outputformat=1 and no mp4 muxer. What I
1) audio is better, but tracks keep "skipping" or jittering every 2-3
2) the mp4 muxer is there for a reason; without it, output files have no tags
(artist, album, title, etc.)
I'd be happy to test with feeding AAC audio framed to the mp4 muxer, if you or
someone else can please point me to directions as to how to setup the pipeline.
I messed around with the bitrate parameter of faac, and I found that it
dramatically affects the playability of the output file. In particular,
lowering the bitrate makes everything worse (playback is slowed down and
processor usage goes sky high -- on a double core Pentium D!), which seems
counterintuitive to me...
I might find some time to try more settings later.
