y proposal(as for now there's no name ... let's call it 'y') ;)

My idea is to create 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!

• 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 usuful 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 , GNU Autotools, ...

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 do good)

• [http://live.com/liveMedia/ live.com] for rtp/rtsp/rtcp support

• [http://www.dennedy.org/ future libiec61883] for dv camcorder

• [http://libdv.sourceforge.net/ libdv] for a better dv handling ?

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 ?
• libirified Sox

• 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 )
