title: Pushing images into a gstreamer pipeline
body: <p>After playing around with some toy applications, exploring the
  documentation and googling around (including the mailing list
  archives) I am still puzzled for what I would think is a rather common
  use case.</p>
  
  <p>I have an existing code that generates images (in memory) and I would
  like to push these images into a gstreamer pipeline (to create a flv
  video at the end).</p>
  
  <p>I could not find an "obvious way to do it". My best guess will be to
  dig in the source code of GstMultiFileSrc and its parent GstPushSrc,
  to figure it out.</p>
  
  <p>Could any of you point me out to the "obvious way" of doing this ?
  Is it there any related piece of documentation/tutorial/example on this ?</p>
  
  <p>Once I have the input right, the rest is a piece of cake, thanks to
  Gstreamer awesomeness !
  (something like "my magic input ->  ffmpegcolorspace ! ffenc_flv !
  flvmux ! filesink location=desktop.flv" )</p>
  
  <p>Thanks for your answers.</p>
