Quick tip on encoding video for your iriver E100


So you bought one of these players just to find out that

  • It supports just a subset of MPEG4 SP (strictly speaking it is NOT MPEG4 SP complaint).
  • The bundled movie converter, while based on MPlayer and FFmpeg does not work on Linux.

Let alone the blatant GPL violation (friends at MPlayer/FFmpeg fame says a team of assassins was already dispatched iriver's way. Rumor has it includes members of the Project From Hell age -- you have been warned).

I thought about quickly drafting a better and cross plataform movie converter but then realized I should maybe give you a working encoding recipe first (not to mention I have a lot on my TODO already), so, here it is:

  • Install MPlayer. If the one you installed has support for XviD in mencoder you are golden, otherwise you might have to build and install a custom one (If you use debian and maybe in ubuntu too, installing libxvidcore4-dev before building MPlayer from svn should be enough).

  • Proceed to encode your video with this cmd line:

    mencoder INFILE.SOMETHING -vf scale=320,expand=320:240 -oac mp3lame -lameopts abr=128 -ovc xvid -xvidencopts bitrate=600:max_bframes=0:vhq=4 -of avi -o OUTFILE.AVI


Of course you can customize this, specially the -vf part. I myself have to try other codecs yet.

Special thanks go to Robert Swain who helped figuring this
out yesterday. The dude has a lot of talent encoding with constrained/crippled neat gadgets as targets. Go read his blog and send him my regards.



Shame on you Iriver..., Shame on you.

Here is the command used by the included iriver software to perform the conversion using mencoder. Although I did tweak the scale sizes:

mencoder -noodml INFILE.NAME -o OUTFILE.AVI -ofps 23.000 -vf-add crop=0:0:0:0 -vf-add scale=320:240 -vf-add expand=320:240:-1:-1:1 -srate 44100 -ovc xvid -xvidencopts bitrate=280 -oac mp3lame -lameopts vbr=0 -lameopts br=96 -lameopts mode=0 -lameopts aq=7 -af volnorm -xvidencopts max_bframes=0 -xvidencopts nogmc -xvidencopts noqpel -mc 1 -info comment="brand=iriver/model=E100"\
