• Process audio and video independently

  27 février 2012, par Eric

  due to the unpopularity of my last posts here and here , I'll try something else.
  I have corresponding audio (.wav) and video files (.mpg). Let's consider that those two streams where recorded synchronously. I want to process both stream, with opencv for the images, and with "I don't know which audio lib" (you tell me ?) for audio, and I want to process those streams online and keep the synchronicity.
  Note that the length of the video is less that 2 minutes.

  Thanks for any help !

• what is the best open source framework for programmatically producing .mov or .flv video files ? [closed]

  12 mai 2013, par Andrew Arrow

  I would like to programmatically produce a simple animation video. Don't think "Toy Story" level of animation, think simple stick figures moving around the screen and other very simple lines and dots in black and white only. The point of the video is to explain a complicated scientific concept with a 5 minute video vs. pages and pages of text trying to describe images with words.

  What is the best open source framework to make a .mov or .flv file that I can then upload to youtube or vimeo. I could use ImageMagick to write out jpeg after jpeg, and then ffmpeg to turn those jpegs into a .mov file. But is there a better framework out there for simple animation like this ? I feel like the ImageMagick to ffmpeg route is going to involve a lot of me writing code from scratch to make a stick figure walk across the screen.
