there is a little guide in progress on how to use cli apps and avisynth to make qt7 compatible mp4 files for web:
http://somestuff.org/x264_qt/h264_in_quicktime7.html

(most of the stuff is ripped from doom9.org forums)

- suggestions welcome, especially considering that perfect/fast x264 command line (or command lines ranging from 300 to 1000 kbps) and faac as well (whats a good quality based preset at around 128kbps?)
- probably avisynth script could need some help as well, considering that input is dv pal.

thanks muchly. will try this tomorrow.

i'm trying to make mp4 stuff that quicktime can take, but i keep getting error -50 (on PC and mac)

cool, hopefully you will find time to post your findings (concerning the compatibility.)

q: is it possible to construct real piping from mplayer to faac on winxp cmd, if yes how would that command line look like?

this seems to work:
mplayer -ao pcm -vo null -vc dummy film.avi&faac -b 128 --mpeg-vers 4 audiodump.wav
(but thats 2 pass process and not real piping)

You can go like 'mencoder -oac faac' as well (with recent enough mencoder build)
As for piping I would probably go with ffmpeg instead.

ak: ok, tnx, iam trying that, but it seems like iam unable to construct some nice command line for xvid+faac to avi combo, the one that will repack nicely to mp4 afterwards with mp4box, mabye i should separate the video + audio to separate pieces somehow? is mencoder capable of exporting into aac or mp4 audio only? everything seems pretty buggy + there is no real docs to find on how to use faac with mencoder either.

Ahm, yeah, it's just that I saw they added faac support to cvs recently
But as mencoder is pretty-much avi-centric when it comes to muxers and not really intended for audio-only encodings, it seems there's not much use for libfaac.
As for usage, check http://www.mplayerhq.hu/MPlayer/DOCS/man/en/mplayer.1.html for '-faacopts'.

Still, imo, piping from ffmpeg to faac would be least hassle possible, if you need lavc decoders. Then again it can encode using libfaac directly as well.

ak, tnx, well i guess iam just a lame searcher..., anyway the 'x264 for qt' guide (and the bat file) mentioned in my 1st post was updated and seems to deliver consistently compatible results (according to some finds reported in doom9.org forums).
