No, I'm not the author but such an app was on my wishlist for long. I can only advice you to communicate with the author on his blog (http://jensge.org/2012/03/introducing-helium/). He probably likes feedback or help (He set up a GIT repository).

You're already communicating with him, it's phako ;-)

An UPnP media controller indeed would be very welcome, it really augments the media server on our N9.

But I'm afraid I fail to see how this would provide streaming-audio-out-to-upnp-capabilities. The "GST Launch" in the screenshot could very well be a Rygel installation on his local machine. Indeed, Rygel supports streaming from gstreamer, but our N9 is lacking the library for that, as was discussed earlier. But seen his work, Jens might very well be able to pull it off :)

Yeah, that's my local machine. Sorry if that caused confusion.

No it doesn't have one yet as it was (and is still) lacking some basic but necessary capabilities (like proper error handling). Still I wanted to get the news out since so many people were waiting for such a tool. Btw, we should probably move over to the N9 dlna thread instead of hijacking this one.

Re: [Request]stream audio output over wifi

heyyyy, so
gst-launch-0.10 pulsesrc device=sink.hw0.monitor ! mulawenc ! rtppcmupay ! udpsink host=192.168.1.100 port=5000

works wonderfully.

anyone happen to know how i could do the same with a microphone? i want to send a sink on my computer to the n9 over a network.

Re: [Request]stream audio output over wifi

so i have no idea what i actually want to do with the stream on the n9 side.
i suspect that what i want to do is change nokia application behaviour, which is impossible. possibly what i want to do is pulse-magic, though, so if anyone knows what i want, lemme know.

getting the stream to the n9 was simple. my goal is to have the phone app use my the stream {from my laptop's microphone} instead of the n9's microphone.

laptop-microphone => n9-loudspeaker
laptop:
gst-launch-0.10 pulsesrc device=alsa_input.pci-0000_00_1b.0.analog-stereo ! audioconvert ! audio/x-raw-int,channels=1,depth=16,width=16,rate=44100 ! rtpL16pay ! udpsink host=$n9ip port=3200

n9:
gst-launch-0.10 -v udpsrc port=3200 ! "application/x-rtp,media=(string)audio, clock-rate=(int)44100, width=16, height=16, encoding-name=(string)L16, encoding-params=(string)1, channels=(int)1, channel-positions=(int)1, payload=(int)96" ! rtpL16depay ! audioconvert ! pulsesink

Re: [Request]stream audio output over wifi

Stereo(!) microphone from N9 to PC:

PC:

Code:

gst-launch udpsrc port=3200 ! "application/x-rtp,media=(string)audio, clock-rate=(int)44100, encoding-name=(string)L16, channels=(int)2, payload=(int)96" ! gstrtpjitterbuffer latency=1000 ! rtpL16depay ! audioconvert ! autoaudiosink

N9:

Code:

~ $ gst-launch-0.10 autoaudiosrc ! audioconvert ! audio/x-raw-int,channels=2,depth=16,rate=44100 ! rtpL16pay ! udp

sink host=<IP of PC> port=3200

The PC-side actually works in both Linux as Windows (GST .10.7 beta, as mentioned before)

This is uncompressed audio. But still the two problems remain: how to get the original audio from example the music player, without the need for pluging-in headphones? And why won't TCP work? (Well, the Windows version seems to lack TCP...)

Also, the jitter buffer is at full second. Much lower and it breaks. :(

More interesting stuff ahead: using the N9 as Dolby Headphone decoder: :cool:

Code:

~ $ gst-inspect-0.10 | grep Dolby

nokiadhmmix:  nokiadhmmix: Dolby Headphones Mobile mixer

nokiaddpdec:  nokiaddpdec: Dolby Digital/Dolby Digital Plus decoder

But I don't know how to use them, and what the exact options are.

Of course, GStreamer can stream video as well. It should be possible to stream video directly to VLC on a PC right over the internet. I don't know about the streaming possibilities of HTML5 or Flash. Would be cool though to embed a videostream in a website. Any suggestions here too?

Re: [Request]stream audio output over wifi

pretty cool fuzzilogic.

im still interested in using my laptop microphone in the phone app. if anyone can think of a way to do this, i would really appreciate it.
