play_yan A movie and audio player for the Games/Gameboy Advance (SP) and Nintendo DS.

The picture quality is quite good but the downsampling of the sound to 8kHz does not do good. Maybe its the downsampling of ffmpeg that creates such bad quality. However, watching movies is okay if you use the integrated headphone jack. The sound of the built-in speakers of the Nintendo DS is not tolerable.

The quality of MP3 playback is excellent. But again, the use of headphones is recommended.

A full-length movie takes about 350-400MB of space. On a 1GB SD-Card you can store two movies and a few MP3s.

All in all, the whole design and usage is very japanese. Little stars spinning, a bird as menu guide and fishes and a car moving over the screen make it definitely more a gaming device than something that could compete with a Games/PSP.

Converting movies

I use the following command line to command line to convert directly from DVD. As I use MacOS X I tried >>FFmpegX but it comes with a version of >>ffmpeg that seems to have a broken ASF converter. The movies are not even recognised on the play-yan. A self-built version (build 4751) works great though.

Save to playyan.sh and make executable with chmod +x playyan.sh

#! /bin/sh
ffmpeg -y -i "$1" -title "$2" -timestamp "" -bitexact -hq -me full -strict 3 -vcodec mpeg4 -vtag MP4S -s 240x176 -r 30 -b 480 -acodec g726 -ac 1 -ar 8000 -ab 32 -f asf $2".ASF"

With some movies the audio is out of sync. I have not found out why yet.

Examples

I tried a few movies and videos and here is what comes out:

MoviePicture QualitySound QualityCommentsPicture
>>Eminem's Moshokayvery badLooks like converting the bass and music in general to 8kHz generates a lot of noise. There are artefacts but in general the quality is quite okay.
The 5th ElementokayokayWatchable. I have more problems with the english language (somehow muted).link=space/Games/Nintendo DS/Play-yan/The5thElement.png
TrainspottingokayokayQuite a few artefacts and the general darkness is bad. Watchable though.link=space/Games/Nintendo DS/Play-yan/trainspotting.png
となりのトトロ
My Neighbor Totoro
greatgoodAnimations are very good on the screen and since this movies has not many scenes with music the sound conversion is quite good.link=space/Games/Nintendo DS/Play-yan/totoro.png
Princess MononokegoodgoodHere, almost the same as for となりのトトロ applies. However, there are more camera moves and more sound, so this makes it a wee bit less enjoyable.link=space/Games/Nintendo DS/Play-yan/mononoke.png
Princess BladeokayokayA little dark even for the backlit DS screen but watchable nevertheless.link=space/Games/Nintendo DS/Play-yan/princessblade.png
