  • Open a shell/command line in ffmpeg directory

With the Makefile Simply use make.

With CMake

  • mkdir cbuild && cd cbuild
  • On *NIX cmake -DCMAKE_TOOLCHAIN_FILE=DevkitArm3DS.cmake ..
  • On Windows cmake -DCMAKE_TOOLCHAIN_FILE=DevkitArm3DS.cmake -G"Unix Makefiles" ..
  • make More information on the 3ds-cmake repository.

Usage At the moment, you have to specify the file path in the main.c file at compilation time.

Features

  • Video
  • MPEG4, H.264
  • Hardware acceleration with Y2R for YUV -> RGB conversions

TODO

  • Audio
  • Sync and time adjustment
  • File Browser and Menu
  • Subtitles
  • More formats and track selection
  • Use the MVD service for the new3ds #Random informations Use a video with dimensions multiple of 8 for best performance ! Videos up to 1024x1024 are supported (but eh, that won't run fullspeed you know)
  • Actually only if width < 800 if you set up the framebuffers to be using RGBA Prefer simple MPEG4 to H.264 ! (H.264 is ~4 times slower)

Some stats (video only, old 3ds) :

  • 400x240 mpeg4 -> 37fps
  • 400x240 h264 -> 16fps The new3ds is way faster
