Aplicación creada por Dominic Ludlam que permite reproducir video en la Nintendo DS.

How to watch videos
===================

First you will need to DLDI patch the DSVideo.nds file.  DSVideo doesn't contain any drivers by default, so you'll have to patch it even if you have a homebrew device that doesn't usually need patching, like the supercard. 

When run, DSVideo presents a filesystem browser to find video files made with the encoder (described below) which must have a filename ending with ".dsv".  By default, the player will start in a directory called "videos" if it exists, or the top level otherwise.  You can play a video file either by touching it on the screen or by using the up and down keys to highlight it then pressing the A button to start it playing.

While watching, you can use the touchscreen controls to rewind, fast forward, pause, seek, return to the video selection screen and to change the screen brightness.  In addition to the touch screen, fast- forward and rewind can be used with the left and right keypad keys and shoulder buttons.  The A button will toggle between pause and play, X will change the brightness and select will go back to the select screen.

NOTE FOR THE R4:  There is a special version of DSVideo for the R4, which has been patched with a slightly modifier version of the R4 dldi driver (source is also included here).  If you have an R4, you'll need to use the r4tf7.dldi patch and stop the R4 from autopatching it when it boots.  This can be done with the 'dldinoap' tool (source is in the thirdparty directory).

How to encode videos
====================

The encoder is a command line utility.  The basic usage is very simple - the command:

   dsvideo input_video.avi

will convert the file 'input_video.avi' into a file called 'input_video.dsv' which can then by copied onto your homebrew flashcard.

By default, 16:9 (or other widescreen sizes) will be encoded as centre- cut-out, meaning the height will fit the DS screen and the sides will
be removed.  The original video size can be kept by passing the "-l" option to the encoder, for example:

   dsvideo -l input_video.avi

There are some other options to control the encoder which are explained (briefly) by running the encoder with no arguments.

DSVideo was developed by Dominic Ludlam, with artwork and design by Denise Wilton, and additional artwork and the website by Nick Ludlam. Nick also made the spiffy intro video.  Many thanks to Lee Maguire for testing and feedback.

The sound track for the intro video is by James Tubbritt (Sharp), downloadable from http://fxhome.com/sounds/

The following additional software is used:

  •  devkitPro.  Used to build the decoder.
  •  FFMpeg.  Used by the encoder to provide   input video and audio data.
  • TwoLAME.  Used by the encoder for audio   encoding.
  • LibFB.   Used by the decoder to access the flash card on the DS.
  •  Freetype2.  Used during the build process   to convert a freetype font to a bitmap font usable on the DS.
  •  * Libungif.  Used during the   build process to convert images into a format usable on the DS.
  •  Yasm.  Used while building   the encoder.
