tripude is about creating '''a new video editor''' with usability and user at center ...
create "umanesimo" in software ! ( ?? )

----
A new video editor with a vertical timeline (ala soundtracker or protracker)

==== AIM ====

The application should be: 
 * '''usable for everyone'''! people with handycap, children, older
 * '''easily usable'''. Users should be able to use the first they see it. They should not be obliged to read tons of man pages or documentation for basic use FRTFM (Fuc* RTFM)
 * '''easily playable''' . Enjoy video! play! produce! '''COMMUNICATEEEE'''! :D
 * '''awesome''' not ugly(eye friendly). Users(not developers nor hackers nor nerds nor geeks) cares about what they see, althought it's a computer.
 * '''finger based''' video editing. Should be usable with touchscreens.

==== TECHNICAL CHOICE ====
 * The best way '''to have full control''', and have a good ui is to implement a customized one with [[http://www.libsdl.org|libsdl]] -> see SdlWidget
 * implements useful HIG:

==== AIM ====
 * Support every video and audio codec and format available (seekable)
     * encoding
     * decoding
 * Support streaming
     * network (remote video)
     * v4l1/v4l2 devices
     * ieee1394 
     * non-seekable files
 * Support "live" recording 
 * Easy to Use GUI
 * GUI and core communicate with OSC 


==== TECHNICAL CHOICE ====
 * C language (but with objects)
 * GNU Autotools
 * gprof, gcov
 * [[http://www.stack.nl/~dimitri/doxygen/|doxygen]] to document code

===== video =====
 * [[http://ffmpeg.sourceforge.net/index.php|ffmpeg]] to decode video files
 * [[http://libmpeg2.sourceforge.net/|libmpeg2]] to decode mpeg2 files (as for now ffmpeg it's buggy for mpeg2)
 * [[http://mplayerhq.hu|libmpdemux]] from mplayer developers to demux files (as for now ffmpeg demuxing it's not so good)
 * [[http://live.com/liveMedia/|live.com]] for rtp/rtsp/rtcp support
 * [[http://www.linux1394.org/|libiec61883]] for dv camcorder
 * [[http://libdv.sourceforge.net/|libdv]] for a better dv handling ?
 * [[http://cairographics.org|cairo]] for vector support
===== audio =====
 * [[http://portaudio.com/|PortAudio v19]] for cross platform I/O
 * [[http://www.mega-nerd.com/libsndfile/|Libsndfile]] to read audio
 * [[http://sky.prohosting.com/oparviai/soundtouch/|SoundTouch]] for realt time audio processing
 * ffmpeg or lame or libogg/libvorbis to decode files ?
 * [[http://sox.sourceforge.net/|sox]] libirified Sox 

==== AIM (Application features) ====
 * one click preview 
 * video sequencer 
       * clip sequencer
 * video pattern editor
       * multiple video/audio tracks
 * video pattern instrument
       * keyframing  
 * video clip Audio/Video editing
       * looping
       * reverse playback (in realtime)
       * frame accurate
       * fast playback (by frame skip)
       * resampling (render option) 
 * Audio support
       * on the fly resampling
       * pitching/mixing audio tracks
       * time accurate audio editing 
           - drop 1 frames every 1000 frames NTSC ?
 * Remotely controlable (OSC)
 * Realtime Editing supports compressed codecs/format in I frame only,
   MJPEG/DV/MPEG4/ (in file container AVI/QT/Matroska (?) )
   Realtime Editing supports uncompressed formats YUV 4:2:0 / 4:2:2 / 4:4:4 (8 or 10 bit?) 
 * Compressed formats in which not every frame is an I frame need
   to be transcoded into another format    

 * Platforms :Linux/macosx/BSD/Embedded Systems/win32 (?) (the arian apple)

=== TODO ===
 * choose which part of freev/veejay keep
 * write a lot of code! ;)
 * conquer the world.(the always present todo :P )
