Get current downloaded size

[Damián Nohales]

Hi there!

I am developing an application that must play a music file over the
Internet, through HTTP (remote streaming). I am using GStreamer and Python.

Is there a way to know the current amount of time downloaded of the
music file? No the music file duration, but the current data downloaded
by GStreamer expressed in a time unit.

If helps, the code that I using for play the remote music file is the
following:

---
player = gst.element_factory_make("playbin", "player")
player.set_property('uri', "http://www.example.com/myfile.mp3")
player.set_state(gst.STATE_PLAYING)

player.get_bus()
bus.enable_sync_message_emission()
bus.add_signal_watch()
# The on_stopped callback updates the UI when the file playback
# ends.
bus.connect('message::eos', self.on_stopped)
---

Thanks in advance!
Regards!
