[gst-devel] code with optional plugins

[Alexey Fisher]

Hallo all,

i have this kind peas of code:
=======================================================================
  GstElement *maxrate, *scale, *colorspace, *noisefilter, *capsfilter;
  GstPad *ghost, *src;
  GstCaps *caps;

  maxrate = gst_element_factory_make ("videomaxrate", NULL);
  scale = gst_element_factory_make ("videoscale", NULL);
  colorspace = gst_element_factory_make ("ffmpegcolorspace", NULL);
  noisefilter = gst_element_factory_make ("postproc_tmpnoise", NULL);


  gst_bin_add_many (GST_BIN (obj), priv->src, maxrate, scale,
colorspace,
    noisefilter, capsfilter, NULL);
  gst_element_link_many (priv->src, maxrate, scale, colorspace,
    noisefilter, capsfilter, NULL);
========================================================================

i wont to make videomaxrate and postproc_tmpnoise optional. If these are
not installed i will pipeline should work.
Are there any easy option to do this? Or i need to create different
gst_bin_add_many and gst_element_link_many for different situations?

Regards,
