About

This is pulseaudio-dlna. A lightweight streaming server which brings DLNA / UPNP and Chromecast support to PulseAudio and Linux. It can stream your current PulseAudio playback to different UPNP devices (UPNP Media Renderers) or Chromecasts in your network. Its main goals are: easy to use, no configuration hassle, no big dependencies.

UPNP renderers in your network will show up as pulseaudio sinks.

Installation via git

Other linux users can clone this git repository, make sure you have all the dependencies installed and the PulseAudio DBus module is loaded.

Basic requirements

These are the requirements pulseaudio-dlna acutally needs to run. These dependencies will get installed if you install it via the PPA.

• python2.7
• python-pip
• python-setuptools
• python-dbus
• python-docopt
• python-requests
• python-setproctitle

PulseAudio DBus module

Since version 0.2.2 the DBus module should be loaded automatically, if it was not loaded before. It that does not work, you can load the DBus module in Ubuntu via the following command. Note that you have to do this every time you restart PulseAudio (or your computer).

pacmd load-module module-dbus-protocol

Or to make changes persistant edit the file /etc/pulse/default.pa with your favorite editor and append the following line:

load-module module-dbus-protocol

Install it local

The recommend method of using pulseaudio-dlna is to install it local to a python virtualenv. In that way you will keep your system clean. If you don't like it anymore, just delete the folder. For that method you need some additional dependencies.

virtualenv requirements

• python-virtualenv (Ubuntu <= 14.04 Trusty LTS)
• virtualenv (Ubuntu >= 14.10 Utopic)
• python-dev

So all Ubuntu versions prior to 14.10 Utopic need to install:

sudo apt-get install python-virtualenv python-dev

All Ubuntu versions above install:

sudo apt-get install virtualenv python-dev

Installing & starting

Change to the project root folder and start the installation via:

make

After that you can start pulseaudio-dlna via:

bin/pulseaudio-dlna

Install it to your system

Since some people like it more to install software globally, you can do that too. In many software projects this is the default installation method.

Installing & starting

Change to the root folder and start the installation via:

make install

After that you can start pulseaudio-dlna via:

pulseaudio-dlna

Using

pulseaudio-dlna should detect the ip address your computer is reachable within your local area network. If the detected ip address is not correct or there were no ips found, you still can specifiy them yourself via the host option (--host <your-ip>)

Right after startup it should start searching for UPNP devices in your LAN and add new PulseAudio sinks. After 5 seconds the progress is complete and you can select your UPNP renderers from the default audio control.

In case you just want to stream single audio streams to your UPNP devices you can do this via pavucontrol.

You can install pavucontrol in Ubuntu via the following command:

sudo apt-get install pavucontrol

Note that pulseaudio-dlna has to run all the time while you are listening to your music. If you stop pulseaudio-dlna it will cleanly remove the created UPNP devices from PulseAudio and your UPNP devices will stop playing.

Since 0.4, new devices are automatically discovered as they appear on the network.

Options:
    --create-device-config                 Discovers all devices in your network and write a config for them.
                                           That config can be editied manually to adjust various settings.
                                           You can set:

                                             - Various codec settings such as the mime type, specific rules or
                                               the bit rate (depends on the codec)
                                           A written config is loaded by default if the --encoder and --bit-rate options are not used.

Samples:

• pulseaudio-dlna will start pulseaudio-dlna on port 8080 and stream your PulseAudio streams encoded with mp3.
• pulseaudio-dlna --encoder ogg will start pulseaudio-dlna on port 8080 and stream your PulseAudio streams encoded with Ogg Vorbis.
• pulseaudio-dlna --port 10291 --encoder flac will start pulseaudio-dlna on port 10291 and stream your PulseAudio streams encoded with FLAC.
• pulseaudio-dlna --filter-device 'Nexus 5,TV' will just use devices named Nexus 5 or TV even when more devices got discovered.
• pulseaudio-dlna --renderer-urls http://192.168.1.7:7676/smp_10_ won't discover upnp devices by itself. Instead it will search for upnp renderers at the specified locations. You can specify multiple locations via urls seperated by comma (,). Most users won't ever need this option, but since UDP multicast packages won't work (most times) over VPN connections this is very useful if you ever plan to stream to a UPNP device over VPN.

Device configuration rules

Most times the automatic discovery of supported device codecs and their prioritization works pretty good. But in the case of a device which does work out of the box or if you don't like the used codec you can adjust the settings with a device configuration.

If you want to create a specific configuration for your devices you can do that via the --create-device-config flag. It will search for devices on your network and write a config for them. It will look for / write them at:

• ~/.local/share/pulseaudio-dlna/devices.json (prioritized)
• /etc/pulseaudio-dlna/devices.json

The purpose of this is that the application should do the most work for the user. You just have to edit the file instead of writing it completely on your own.

Let's make an example: I started the application via pulseaudio-dlna --create-device-config and that is what was discovered:

    "uuid:e4572d54-c2c7-d491-1eb3-9cf17cf5fe01": {
        "rules": [],
        "flavour": "DLNA",

                "rules": [],
                "identifier": "l16",
                "sample_rate": 48000,
                "mime_type": "audio/L16;rate=48000;channels=2"
            },
            {
                "channels": 2,
                "rules": [],
                "identifier": "l16",
                "sample_rate": 44100,
                "mime_type": "audio/L16;rate=44100;channels=2"
            },
            {
                "channels": 1,
                "rules": [],
                "identifier": "l16",
                "sample_rate": 44100,
                "mime_type": "audio/L16;rate=44100;channels=1"
            }
        ]
    }

It was detected that the device supports the following codecs:

• audio/mp3
• audio/flac
• audio/L16;rate=48000;channels=2
• audio/L16;rate=44100;channels=2
• audio/L16;rate=44100;channels=1

If you don't change the configuration at all, it means that the next time you start pulseaudio-dlna it will automatically use those codecs for that device. The order of the list also defines the priority. It will take the first codec and use it if the appropriate encoder binary is installed on your system. If the binary is missing it will take the next one. So here the mp3 codec would be used, if the lame binary is installed.

You can also change the name of the device, adjust the mime type or set the bit rate. A null value means default, for bit rates this is set to 192 Kbit/s.

In that case I want to rename my device to "Living Room". Besides that I don't want the L16 codecs, so i simply remove them and i want my mp3 to be encoded in 256 Kbit/s.

    "uuid:e4572d54-c2c7-d491-1eb3-9cf17cf5fe01": {
        "rules": [],
        "flavour": "DLNA",
        "name": "Living Room",
        "codecs": [
            {
                "rules": [],
                "bit_rate": 256,
                "identifier": "mp3",
                "mime_type": "audio/mpeg"
            },
            {
                "rules": [],
                "identifier": "flac",
                "mime_type": "audio/flac"
            }
        ]
    }

But as it turns out this device has a problem with playing the mp3 stream when you don't specify the --fake-http-content-length flag. Let's say flac works without the flag. So, you can add a rule for that to that device.

    "uuid:e4572d54-c2c7-d491-1eb3-9cf17cf5fe01": {
        "rules": [],
        "flavour": "DLNA",
        "name": "Living Room",
        "codecs": [
            {
                "rules": [
                    {
                        "name": "FAKE_HTTP_CONTENT_LENGTH"
                    }
                ],
                "bit_rate": 256,
                "identifier": "mp3",
                "mime_type": "audio/mpeg"
            },
            {
                "rules": [],
                "identifier": "flac",
                "mime_type": "audio/flac"
            }
        ]
    }

That's it. pulseaudio-dlna will automatically use that config if you don't use the --encoder or --bit-rate options.

Known Issues

• Distorted sound

  If you experience distorted sound, try to pause / unpause the playback or changing / adjusting the volume. Some encoders handle volume changes better than others. The lame encoder handles this by far better than most of the other ones.

• There is a delay about a few seconds

  Since there is HTTP streaming used for the audio data to transport, there is always a buffer involved. This device buffer ensures that even if you suffer from a slow network (e.g. weak wifi) small interruptions won't affect your playback. On the other hand devices will first start to play when this buffer is filled. Most devices do this based on the received amount of data. Therefore inefficient codecs such as wav fill that buffer much faster than efficient codecs do. The result is a noticeable shorter delay in contrast to e.g. mp3 or others. Note, that in this case your network should be pretty stable, otherwise your device will quickly run out of data and stop playing. This is normally not a problem with cable connections. E.g. I have a delay about 1-2 seconds with wav and a delay of about 5 seconds with mp3 with the same cable connected device. You can decrease the delay when using wav or using high bit rates, but you won't get rid of it completely. My advice: If you have a reliable network, use wav. It is lossless and you will get a short delay. If you have not, use another encoder which does not require that much bandwidth to make sure your device will keep playing. Of course you will be affected from a higher delay.

Troubleshooting

• My device does not get discovered by pulseaudio-dlna

  The computer pulseaudio-dlna is running on and your device needs to be in the same network. In uncomplicated home LANs this is normally the case. You can test if other applications are able to find your device, e.g. BubbleUPnP (Android application). If they do it is likely that you are using a firewall / iptables. Try disabling it. If you verified that your firewall is blocking, you should use the --msearch-port <port> option and open port 8080/tcp, port 1900/udp and port <port>/udp.

• The device is successfully instructed to play, but the device never connects to pulseaudio-dlna

  Check if your are using a firewall / iptables. If that works, open port 8080/tcp and port 1900/udp.

• The device is successfully instructed to play, but the device immediately disconnects after some seconds

  Some devices do not stick to the HTTP 1.0/1.1 standard. Since most devices do, pulseaudio-dlna must be instructed by CLI flags to act in a non-standard way.

  • --fake-http-content-length

    Adds a faked HTTP Content-Length to HTTP 1.0/1.1 responses. The length is set to 100 GB and ensures that the device would keep playing for months. This is e.g. necessary for the Hame Soundrouter and depending on the used encoder for Sonos devices.

Tested devices

A listed entry means that it was successfully tested, even if there is no specific codec information available.

¹) Works when specifing the --fake-http-content-length flag

²) Is capable of playing the codec, but does not specifiy the correct mime type

³) Works since 0.4.5 (--fake-http-content-length is added automatic)

⁴) The device needs to be in SERVER mode to accept instructions

⁵) Was reported to buffer really long. Approximately 45 seconds

⁶) Was reported to have issues being discovered. Make sure you run the latest firmware

⁷) Reported to need a --request-timeout of 15 seconds to work. Since 0.5.0 the timeout is set to that value.

⁸) Stuttering at 256kbit/s and pretty unstable at 320kbit/s

⁹) The manual states it is supported. No success yet, neither with --fake-http-content-length nor with increased timeout values

Supported encoders

You can select a specific codec using the --encoder flag followed by its identifier.
