HOWTO: Convert AVI to MP4 for the Video Ipod

**Baens** · January 7th, 2006

I have taken a AVI file and converted to the correct mp4 to put it onto my 30GB iPod. I have taken notes and heres what Ive come up with. I hope it helps!

First get the latest CVS with this:

Code:

cvs -z9 -d:pserver:anonymous@mplayerhq.hu:/cvsroot/ffmpeg co ffmpeg

This will make a ffmpeg dir and get all the needed files off the server (duh i guess but just explaining everything

)

You then get into that dir and need to configure the build. For some reason this part was the hardest for me to get. I had to run the following command before i ran the ./configure. This will pull everything ffmpeg needs and shouldn't give any build errors.

Code:

sudo apt-get build-dep ffmpeg

Make sure to have the sources in the repositories correct.

as well get the following 2 commands for libfaad-dev and libfaac-dev and the xvid librarys

Code:

sudo apt-get install libfaac-dev

Code:

sudo apt-get install libfaad2-dev

Code:

sudo apt-get install libxvidcore4-dev

Ok so ready to configure for build heres what i used:

Code:

./configure  --enable-gpl --enable-pp --enable-vorbis --enable-libogg --enable-theora --enable-a52 --enable-dts --enable-dc1394 --enable-libgsm --disable-debug --enable-faac --enable-xvid

Ok now lets build

Code:

make

Let it run through, takes a few minutes on a 2GHz

Once completed go ahead and install it with:

Code:

sudo make install

Done!

Now to convert here is the command I used, it doesnt do a great job at making the files smaller but it works as of right now and Im working on getting a better way of getting the files smaller

Code:

ffmpeg -y -i input.avi -b 768 -s 320x240 -vcodec xvid -ab 128 -acodec aac -ac 2 -ab 64 -f mp4 output.avi

And that is all to it! Took me about 10 minutes to convert a 45 minute show.

I hope this helps someone because I have been looking everywhere to find a solution to this. And if this doesn't help anyone...well umm Im sorry Im no help still a total newbie at this stuff.

All of that can be done in one step:

Code:

sudo apt-get install ffmpeg

Except that the version of FFmpeg in the repositories is more than 6 months old, and the .mp4 muxer has seen some very heavy development over those 6 months. (Read: it now will probably work

).

That said, there are a number of things not quite right: you're creating a file "output.avi" which is really an MP4 file - you should probably call it "output.mp4" instead. And I think that you need some additional ratecontrol parameters - I believe that the command line you used will, under certain circumstances, produce files that the iPod can't play. There's actually a iPod howto on this very board, and I think it gets that stuff right.

Might I in fact suggest this howto?
