Cannot start pa-dlna in docker container, on Slackware64 14.2 host

cmeljakovo commented 7 years ago

Hi,

I have been trying to run pa-dlna in docker container on my Slack64 14.2, (Linux host 4.4.38 #2 SMP Sun Dec 11 16:18:36 CST 2016 x86_64 Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz GenuineIntel GNU/Linux ), with no success. Pulseaudio is running, dbus-protocol as well, on the host, but still getting some errors. Please review the attached debug log, your help will be much appreciated.

The following are the steps I followed:

bash-4.3$ xhost + access control disabled, clients can connect from any host

bash-4.3$ docker run -ti 12-28 14:27:07 pulseaudio_dlna.rules 12-28 14:27:07 pulseaudio_dlna.rules 12-28 14:27:07 pulseaudio_dlna.rules 12-28 14:27:07 pulseaudio_dlna.rules 12-28 14:27:07 pulseaudio_dlna.notification 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.encoder.avconv 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.codecs 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.application 12-28 14:27:07 pulseaudio_dlna.discover Process Process-3: Traceback (most recent call last): File "/usr/lib/python2.7/multiprocess self.run() File "/usr/lib/python2.7/multiprocess self._target(*self._args, **self._kwargs) File "/usr/lib/python2.7/dist-package self._connect(signals) File "/usr/lib/python2.7/dist-package self.bus = self._get_bus() File "/usr/lib/python2.7/dist-package stdout=subprocess.PIPE).communicate() File "/usr/lib/python2.7/subprocess.py", errread, errwrite) File "/usr/lib/python2.7/subprocess.py", raise child_exception OSError: [Errno 2] No such file or Exception in thread zeroconf-ServiceBrowse Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", self.run() File "/usr/lib/python2.7/dist-package self.zc.send(out) File "/usr/lib/python2.7/dist-package bytes_sent = s.sendto(packet, 0, error: [Errno 1] Operation not permitted --net host -v /etc/passwd:/etc/passwd --user cmelo sesceu/pulseaudio-dlna --debug DEBUG Loaded rules: DEBUG DISABLE_DEVICE_STOP = <class 'pulseaudio_dlna.rules.DISABLE_DEVICE_STOP'> DEBUG FAKE_HTTP_CONTENT_LENGTH = <class 'pulseaudio_dlna.rules.FAKE_HTTP_CONTENT_LENGTH'> DEBUG REQUEST_TIMEOUT = <class 'pulseaudio_dlna.rules.REQUEST_TIMEOUT'> ERROR notify2 could not be initialized!

After I disabled firewall on the host, I got further, seeing all DLNA renderers on my LAN. Still do not see the audio sink in pavucontrol. What else does it require to install on host?

Thank you.

masmu commented 7 years ago

Hey, you need a proper DBus connection to a running pulseaudio instance. You can try to start pulseaudio and DBus in the container or since DBus can be used over TCP create one to the running pulseaudio instance of the host system.

cmeljakovo commented 7 years ago

;-) Success!

Thank you for your help!

You are welcome. Is it completely running? Could you show me the docker recipe?

cmeljakovo commented 7 years ago

I will test it out thoroughly, to prove it works in KDE4 on my test machine next week and will post the recipe as well. The container I used is: https://hub.docker.com/r/sesceu/pulseaudio-dlna/

cmeljakovo commented 7 years ago

Happy New Year!

I've been trying to get it to work, but still no success in multiple distros. Can you shed some light, what mechanism/protocol is used when pa-dlna is creating the audio output sink in pavucontrol, please? Is it using dbus or http 4317 on pa..?

Thank you.

masmu commented 7 years ago

Please take a look at the pulseaudio.py ... it is using DBus to get all the information about sinks and streams and it uses CLI tools like pactl to create the sinks and for loading modules. And I guess this will be a problem since you are running the software in a container. I am seeing the following problems:

Loading the dbus module in a container should be problematic, but this is just gonna be tried when there is no DBus session found.

def _get_bus(self):
    try:
        server_address = self._get_bus_address()
        return dbus.connection.Connection(server_address)
    except dbus.exceptions.DBusException:
        subprocess.Popen(
            ['pactl', 'load-module', 'module-dbus-protocol'],
            stdout=subprocess.PIPE).communicate()

Creating sinks from the container is also a problem for the same reason.

def create_null_sink(self, sink_name, sink_description):
    cmd = [
        'pactl',
        'load-module',
        'module-null-sink',
        'sink_name="{}"'.format(sink_name),
        'sink_properties=device.description="{}"'.format(
            sink_description.replace(' ', '\ ')
        ),
    ]
    module_id = int(subprocess.check_output(cmd).strip())

As well as deleting them.

def delete_null_sink(self, id):
    cmd = [
        'pactl',
        'unload-module',
        str(id),
    ]
    try:
        subprocess.check_output(cmd)

Switching back a sink ... same reason

def switch_to_source(self, index):
    cmd = [
        'pactl',
        'move-sink-input',
        str(self.index),
        str(index),
    ]
    subprocess.check_output(cmd)

I know what you are thinking right now... Why are you using DBus to get all the information but not to also control pulseaudio? Because the DBus interface is just for quering information and you cannot control pulseaudio the last time I checked. There is just using the CLI tools or using the c-types bindings.

cmeljakovo commented 7 years ago

...I think your are absolutely correct. Let me check it out, try running it manually, to see the behaviour... I will post my finding sthen.

Thanks again.
