My Way of Life

I wrote a new article about mp3 and amr for mobiles…way more easy than this one. Read it here.

The content of this post is old enough to forget it

*** Only for Linux!! ***
Eva and me have been searching a way to get music for our new Sharp 770SH for a while now. It’s very difficult as the size of the mp3’s are very high for a cell phone and the AMR format was our best option.

So I started to search the way I could do such thing…and it has been hard to find. But then the amazing ffmpeg came into my life

At the beginning I had a broken system (fucking Ubuntu….crap in all the possible way), then I installed Debian Testing AMD64 and I realized there is no source for 64bits architectures (or that’s what I thought! I just realized it’s the same source…duh!), so installed Debian Testing for 386 and did the trick…which took me around an hour to figure it out.

First, download the source for ffmpeg: (you will need subversion)

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

then change to the just downloaded source: cd ffmpeg.

Download this patch and aply it.

bzcat amr-fixed.patch.bz2|patch -p0

This might create another folder inside ffmpeg called ffmpeg-20060612/libavcodec, inside there is other folders, just copy them to the original ffmpeg source.

Then run $ ./configure --enable-amr_nb-fixed --enable-amr_wb, $ make and # make install and that’s it! you got it done!

AVI/MPEG to 3GP
ffmpeg -i videoin.avi -s qcif -r 12 -ac 1 -ar 8000 -b 30 -ab 12 videoout.3gp

MP3 to AMR
ffmpeg -i audioin.mp3 -acodec amr_nb -ar 8000 -ac 1 -ab 32 audioout.amr
