Description

In order to set volume and mute state for a clip with Dual Mono audio a ges_clip_find_all_track_elements is needed. Dual Mono files produces two audio track elements.

Something like the code below would work, but there's probably a more efficient way, since most of code is taken from ges_clip_find_track_element.

GList *
ges_clip_find_all_track_elements (GESClip * clip, GESTrack * track, GType type)
{
GList *tmp;
GESTrackElement *otmp;
GESTrackElement *foundElement;
GList *ret = NULL;

g_return_val_if_fail (GES_IS_CLIP (clip), NULL);
g_return_val_if_fail (!(track == NULL && type == G_TYPE_NONE), NULL);

for (tmp = GES_CONTAINER_CHILDREN (clip); tmp; tmp = g_list_next (tmp)) {
otmp = (GESTrackElement *) tmp->data;

if ((type != G_TYPE_NONE) && !G_TYPE_CHECK_INSTANCE_TYPE (tmp->data, type))  
  continue;  

if ((track == NULL) || (ges_track_element_get_track (otmp) == track)) {  
  foundElement = GES_TRACK_ELEMENT (tmp->data);  
  gst_object_ref (foundElement);  
  ret =  g_list_append(ret,foundElement);  
}  

}

return ret;
}
