C++ (Cpp) transform_value Examples

Example #1

File: gstcogdownsample.c Project: jonasl/gst-svtplayer

static GstCaps *

    GstPadDirection direction, GstCaps * caps)

  const GValue *value;

  caps = gst_caps_copy (caps);

  for (i = 0; i < gst_caps_get_size (caps); i++) {
    structure = gst_caps_get_structure (caps, i);

    value = gst_structure_get_value (structure, "width");
    transform_value (&new_value, value, direction);
    gst_structure_set_value (structure, "width", &new_value);
