The current faac port is 1.26 and thats what gives me invalid aac
streams (won't play in quicktime or mplayer). the previous version
1.25 does work and is usable with mencoder so you might try that
instead of -oac lavc -lavcopts acodec=faac


Thanks! I just re-built faac 1.25 and acodec=aac works again, at least
for the version in ports. I'll have to re-build rc2 and see if it is any
different, but I don't imagine that it will be since it simply said that
it didn't recognize the aac argument for acodec.

I have committed faac/faad to remove drm, so it should be fixed now.

Cheers,
Mezz

Thanks again!
