I'm considering doing the following stuff:

GstVideoColorBalanceMeta owns a GstVideoColorBalance reference.

typedef GstVideoColorBalance {
  GArray *channels; // Array of GstColorBalanceChannel
  GArray *values; // Array of gint
};

Adding the two following functions:

gboolean gst_video_color_balance_set_value (GstVideoColorBalance *
colorbalance, GstColorBalanceChannel *, int);
int gst_video_color_balance_get_value (GstVideoColorBalance * colorbalance,
GstColorBalanceChannel *);

What do you think ?
