With CMake

• mkdir cbuild && cd cbuild

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
