Retrieve bitrate info from MPD

[mancio61]

Hi
I successfully built my own network streamer, using an OLED 16x2 display to show info about artist, title track, elapsed time, etc. I show also the "audio" info, getting those info using the statements:

                audio = m_status['audio'].split(':')
                if len(audio) == 3:
                    sample = round(float(audio[0])/1000,1)
                    bits = audio[1]
                    if audio[2] == '1':
                        channels = 'Mono'
                    elif audio[2] == '2':
                        channels = 'Stereo'
                    elif int(audio[2]) > 2:
                        channels = 'Multi'
                    else:
                        channels = u""

                    if channels == u"":
                        tracktype = "{0} bit, {1} kHz".format(bits, sample)
                    else:
                        tracktype = "{0}, {1} bit, {2} kHz".format(channels, bits, sample)
                else:
                    # If audio information not available just send that MPD is the source
                    tracktype = u"MPD"

The result on the display can be, for example,  "24bits, Stereo, 192/96 kHz".

 I'd like to show also the bitrate (e.g. 320 kbs), but this value is never filled up in the m_status structure (it's always = 0). I saw instead that from Moode web UI, clicking on the "Audio Info", it shows me , for example,  24 bit, 44.1 kHz, Stereo, 320 kbps. That means that in some way this info can be retrieved from MPD. 
Anybody can help me how to?

thanks

its a field named bitrate returned by the MPD status command.

yes, I saw that field 'bitrate' is part of the structure returned by the statement m_status = client.status(). The problem is that its value is always 0 !
I don't understand why (the other ones like elapsed, audio, duration,...etc are correctly filled...). I also try to insert in the code some print (bitrate) statement to see its values on the console, but it sadly always = 0...

You will probably need to examine the source code for the client.status() function to see what its doing

At the end I was able to show it on the display. There was an erroneus indentation in a line of code, that skips the capture of kbps from MPD....
