This application allows the user to record/play videos and take/view photos. The resolution of the top-screen on the 3DS is 400x240

== How to convert and split video.ext into 10 minute pieces ==
<code>
ffmpeg -i video.ext -ss 0 -t 600 -y -r 24 -vsync 1 -vcodec mjpeg -qscale 1 -acodec adpcm_ima_wav -async 1 -ac 2 /DCIM/xxxNINxxx/HNI_%04d.AVI
</code>

== How to convert 2D Video for 3DS ==
<code>
ffmpeg -i video.ext -r 24 -vsync 1 -vcodec mjpeg -qscale 1 -acodec adpcm_ima_wav -async 1 -ac 2 -vf scale=min(400\\,240*a):-1,pad=400:240:abs(ow-iw)/2:abs(oh-ih)/2 /DCIM/xxxNINxxx/HNI_nnnn.AVI
</code>

== How to convert 3D Video for 3DS ==

<code>
ffmpeg -y -i "video.mp4" -s 960x240 -aspect 2:1 -r 20 -vcodec mjpeg -qscale 1 -vf crop=480:240:0:0 -acodec libmp3lame -ar 41000 -ab 96k -ac 2 "left.avi"

</code>

First two lines generate left and right files video, the last line generate the 3D video for the 3DS

Put the file in DCIM\xxxNINxx
