I have a bunch of, I think, x264 encoded AVIs that I'd like to convert to m4v so that I can play with Quicktime. Here's how I created them

First I dump the vob from DVD with this:

$ mplayer -dumpstream -dumpfile new.vob dvd://1

Then I compress it:

$ mencoder -oac copy -o new.avi -ovc x264 -x264encopts crf=18 new.vob

I tried doing this to convertthem to m4v, but it's blowing up...

I tried dumping the h264/acc streams:

$ mplayer new.avi -dumpvideo -dumpfile new.h264
$ mplayer new.avi -dumpaudio -dumpfile new.acc

And remuxing(?) with MP4Box but I'm getting an error:

$ MP4Box -add new.h264#video -add new.aac#audio new.m4v
Cannot find H264 start code
Error importing new.h264#video: BitStream Not Compliant

So not sure what to do now...
