Hi, I have another question about gstreamermm. Trying to print the volume
of the given tracks:
// List the tracks of the mixer.
typedef std::list<Glib::RefPtr<Gst::MixerTrack> > tracks_type;
tracks_type tracks = mixer->list_tracks();
for (tracks_type::iterator iter = tracks.begin(); iter != tracks.end();
++iter)
{
Glib::RefPtr<Gst::MixerTrack const>& track = *iter;
std::cout << track->get_label() << ' ' << mixer->get_volume(track) <<
std::endl;
}
This doesn't work... First I tried get_volume(*iter) but that can't find
a 'get_volume', because the only get_volume that is there demands a
Glib::RefPtr<Gst::MixerTrack const> (note the 'const').
So, I tried to convert *iter (which is a Glib::RefPtr<Gst::MixerTrack>)
to a Glib::RefPtr<Gst::MixerTrack const> in the line before, and indeed,
that fails.
How am I supposed to get the volume of the tracks now?
