I haven’t blogged for a while now, guess I need a new redesigned template, which seems to boost my blogging ability. But here is a simple and short guide to build ffmpeg with the appropriate codecs to encode stuff for the PSP or iPod. These codecs aren’t enabled by default to legal (patent) issues.
You should have the medibuntu repository enabled for this to work.
Get some tools to build tje package along with the ffmpeg source in Ubuntu Intrepid. Then get the appropriate packages to build ffmpeg, and satisfy the evil codec dependencies:
apt-get install dpkg-dev devscripts apt-get source ffmpeg apt-get build-dep ffmpeg apt-get install libmp3lame-dev libfaac-dev libxvidcore4-dev libx264-dev
To finished up, go into the sources directory, build the package with the external codecs and install everything after it finishes building the debian package. Note that the first command is optional, and is just to bump the package version so that is “newer” that the original repositories:
dch -i DEB_BUILD_OPTIONS=externalcodecs dpkg-buildpackage -rfakeroot -us -uc
dpkg -i *.deb
And that is it. Look for scripts that use ffmpeg to encode stuff for the PSP or iPod. There are plenty around. I’ll post my favourite at a later time.
Unfortunately, this isn’t enough to build with all of the codecs. You also need to make another couple patches:
In debian/rules, change
SVN_VERSION := $(shell echo $(SRC_VERSION) | sed -ne ’s/^[0-9]\.[a-z]*//p’)
to
SVN_VERSION := $(shell echo $(SRC_VERSION) | sed -ne ’s/^[0-9:]*\.[a-z]*//p’)
Then run
DEB_BUILD_OPTIONS=internalcodecs,externalcodecs debian/rules get-orig-source
Then edit config-extra-includes.h and change all the defines from 0 to 1
Finally, build with
DEB_BUILD_OPTIONS=externalcodecs dpkg-buildpackage -rfakeroot -us -uc
(the same as above)

I’ve actually continued fighting with it; those steps aren’t quite right. After changing the SVN_VERSION line,
DEB_BUILD_OPTIONS=internalencoders,externalcodecs debian/rules get-orig-source
cd ..
mv ffmpeg_3\:0.svn20080206.orig.tar.gz ffmpeg-debian_0.svn20080206.orig.tar.gz
dpkg-source –no-check -x ffmpeg-debian_0.svn20080206-12ubuntu3.dsc
DEB_BUILD_OPTIONS=internalencoders,externalcodecs dpkg-buildpackage -rfakeroot -us -uc
should leave you with a working ffmpeg.

@ Quentin
Thanks for your feedback, its very enlightening, because in fact, you enabled all codecs, both internal and external. My objective was just those required to encode PSP video, aac xvid and x264, for which I think externalcodecs is sufficient, right ?
I get an error at the end of the build using your original instructions
dpkg-shlibdeps: failure: no dependency information found for /usr/lib/libx264.so.65 (used by debian/libavcodec51/usr/lib/libavcodec.so.51.50.0).

Hi Adam, it seems you are missing some libx264 dependencies. Can you try:
If that package doesn’t exist, look for the available package by searching for it:
Also, check if you have medibuntu properly enabled, as suggested by the link at the top of the post. The you should to build everything again, and let me know.
