Zaurus Multimedia


I don't own the Zaurus anymore so there won't be any updates to this section. I'll keep it online for historical reasons and for reference. The feed will also stay online but won't get any updates or changes anymore.


Despite not being made as a Multimedia-machine in the first place, the Zaurus can do pretty well as an Audio/Video player. The CPU, normaly clocked at 416MHz can be overclocked up to 624MHZ for playing Fullscreen-Video at 640×480 or down to 143MHz for longer batterylife when playing music. Someone made a test playing mp3's with the CPU clocked down to 143MHz and the display off and the Zaurus played MP3's for 24h!. Thats longer than a lot of dedicated MP3-Players last…


For audio-playing I use Kino2. Because it uses mplayer it can play a huge list of different audio-codecs/formats, among them mp2/3, ogg, flac, wav, ac3… I have enabled CPU-Frequency scaling in the settings and set “When Playing audio” to “Power Saving (143/143/71MHz)” (see section Video for screenshots of the settings). It still plays MP3/OGG without skips and the battery lasts a lot longer this way.


After some experiments I got my Zaurus to play Videos at 640×480 with 21fps quiet nicely. So here is my current setup:

The Kino2 Settings

These are the settings for kino2 v0.4.3c from the cacko-feed. The installed mplayer is mplayer-bvdd-iwmmxt also from the cacko-feed (Please note that this settings and the mplayer version are only valid for C1000/C3x00 Zaurii). Here are some screenshots of the important settings (click the images for larger version):

Encoding the Video

Encoding the Video Now that we know how to setup kino2 lets see how to encode the Video and Audio. I use the great mencoder (encoder-program from mplayer). For all who prefer a GUI-Program there is avidemux2 (the settings should be easy to transfer, maybe I will provide a custom profile sometime).

mencoder -vf scale=640:480,expand=::::1,hqdn3d -ofps 21 -oac mp3lame -lameopts cbr:br=64 -ovc xvid -xvidencopts bitrate=460:max_bframes=2:gmc:trellis:cartoon:chroma_opt:vhq=4:chroma_me:hq_ac:keyframe_boost=20:kfthreshold=1:kfreduction=10:max_key_interval=220 -af resample=44100 [other options] [input-file] -o [output.avi]

and some explanation for the […] blocks at the end:

[other options] here you can set things like audio-language or subtitles (see man mplayer for more info)

[input-file] the input file, actually this can be any mrl supported by mplayer

[output.avi] the name of the encoded video, since it is an in avi-format the name should end in “.avi”

A note for Widescreen-content: If your movie is widescreen instead of 4:3 you have to change “scale=640:480” to “scale=640:360” (for 16:9, if your movie has some other weird aspect ratio you will have to calculate the values by yourself ^^)

And now enjoy your favorite movie on the Zaurus ^_^

UPDATE: Avidemux profile

I have uploaded an avidemux profile for avidemux 2.3.0. Get this file and extract zaurus.js to ~/.avidemux/custom/ . After that you can use it by loading the video into avidemux and clicking custom→zaurus.js which should load the settings. After that you can save the image and after the transcoding watch it on your Z with the settings as written above. NOTE: The current profile is for 4:3 content
