[MEncoder-users] sync problem with -oac faac

Interestingly enough i've just done a few short test encodes, and from
the results i'm starting to think that it might in fact be an issue
with x264 and incomplete output files... IIRC on one test with
x264/lame i actually had the same massive sync problem as i was having
with x264/faac. on the next test encode, i tried x264/faac again
(although just single-pass) on the same 2-minute VOB segment and found
that playing the unfinished avi while the encode was running produced
massive sync errors, however once mencoder finished and wrote the
index to the avi, it seems to play back just fine... cuuuuuurious (!)

looks like i may have been chasing a red herring here... i'm going to
fire up mencoder on the full VOB source again and just see if it
dosen't work out... :)

Huh really? Interesting. You know, now that i think of it, i've never
actually checked out a head-to-head audio codec comparison... maybe
it's time i did so :) honestly i just kindof assumed that AAC was
better because it's new (and yes, i *do* know how stupid that souds

Yeah, i'm interested in what settings you use for the vorbis audio...
also, i assume you do two-pass for x264, yes?

Not so into GUIs in general, i like to run all my encodes on the
server to free up my workstations (a pair of laptops anyway -> not
much horsepower.) I am interested in checking out matroska tho... i'll
give that a look.

actually yeah, i have used VLC on win, and like it alot... much nicer
than WMP for sure. like i said though, the main reason i'm not
watching alot of video in windows is that all my media is on the
server on an NFS share, and i'm waaaay too lazy to set up samba on the
server ;)

BTW, thanks for the good advice - V. Condino
