For this particular setup (encoding to baseline for ipod/iphone) the
lavf muxer + global_headers will do just fine, but if you want to go
higher than baseline (which then can include bframes) I strongly
advise to avoid the lavf muxer when bframes are involved. Encoding
either to raw output or an AVI and then using mp4box/mp4creator is the
most reliable way in this situation. If you choose mp4box, then
global_headers is not a requirement if you use switches such as -ipod
in mp4box

of course, you can just use ffmpeg instead and avoid a step, but it's
your choice. I prefer mencoder with its nice filters over "dumb"
ffmpeg, even though the former is pretty broken for anything but AVI,
raw and MPEG2 PS output
