Harold: Thanks a lot for the hints. I embedded the parameters in ffmpeg and it works like a charm!
here is the command I use, hopefully it'll help other with the similar problems. ffmpeg -i casino_royale.avi -acodec aac -ar 48000 -ab 128kb -vcodec mpeg4 -b 1200kb -mbd 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -s 480x368 -title casino_royale casino_royale.mp4 On Mon, Dec 22, 2008 at 5:16 PM, Bill Kendrick <[email protected]> wrote: > > Harold posted from a non-subscribed address: > > ----- Forwarded message from [email protected] ----- > > Date: Mon, 22 Dec 2008 08:23:27 -0800 > From: Harold Lee <[email protected]> > Subject: Re: [vox-tech] video for Apple ipod touch > To: lugod's technical discussion forum <[email protected]> > > Hai Yi wrote: >>Hello all: >> >>It looks like that ipod touch only support mp4 videos format (maybe >>others too, but I don't know).
