steep learning curve

[jer1956]

I came across this because it does what i want. But i know nothing about python. I installed python 2.7.14 on windows 10. I used pip to install twisted. Now i'm stuck. How do i get twisted to use the code?

[provegard]

This project is really old. I don't recall if I have tested it on Windows.

Twisted is a dependency. It's hard to say anything unless you post some log output or error messages.

Hi, Thanks for replying so quickly. Both python and twisted run from the command prompt. All i then did was unzip the app, cd to top folder, and run the twistd command. It says airpnp is an unknown command. Do i need to import the app into python? Do i need a .tac file?

[provegard]

Sorry, now I see what you mean. I'm not sure. I suppose Twisted may have changed since I wrote the readme. I can try on my Windows machine later on.

[jer1956]

That would be a great help. I did find a guide which said i needed to add the parent folder to sys path for the plugin folder to be found. I did that...didn't help.

[jer1956]

It has been pointed out to me that ahari won't work on windows. Do you use that to find upnp devices?

[jer1956]

So do i need to run a virtual linux? It would need to offer up virtual airplay devices detected by tuneblade running on the host windows at the same time.

[jer1956]

I have installed a mini linux build via virtualbox. I then used sudo to install everthing in your readme. Some was already there. I downloaded and unzipped the app. I then used linux File Manager to open a command prompt in it's folder. I ran the twistd command and got the same error. Do we need an older version of it?

[provegard]

I haven't had time to test yet, sorry. I guess Linux is a more viable path than Windows given the dependencies.

[jer1956]

I looked at the listed commands. It says web loads a web app from the folder. So should it be twistd web..called from app folder parent?

[jer1956]

Doing that gets no error. If i try it a second time it says a server is already running.

[jer1956]

I now have a twistd log and pid file in the folder airpnp-master

[jer1956]

This command is meant to run plugin

$ twistd -n web --class=twistdPlugin.resource

[jer1956]

As i posted first. Steep learning curve. Two files are missing. Manifest.in and setup.py.

I have followed aguide and templates to create them. Running sudo python setup.py install

...has added the two plugins as twistd commands.

I tested on my server where I have twistd 13.2.0. Just running twistd airpnp starts the server in the background, as you noted. As described in the README, you may use twistd -n airpnp to start in the foreground instead. You can kill the existing process by its PID found in the pid file.

The server successfully found my WDTVLIVE UPnP device. However, I couldn't connect from my iPad. I suppose the published Avahi configuration is too old. I got an email from someone a long time ago with updated configuration. The diff against airpnp/AirPlayService.py follows:

With these changes, my iPad (not the newest, but with iOS 11) detected the UPnP correctly. However, when I tried to connect, I got an error message. I haven't tested anything beyond that. If you get it to work, feel free to open a PR!

I'm not sure what you mean by steep learning curve. I followed the README in a fresh clone of the repo with success, so as far as I can tell they are correct. Perhaps you have some differences in your machine setup compared to mine?

[jer1956]

I could not get it to run until i installed the plugins by adding the two missing files. I have had to learn how to do that myself. I then had to get virtual box into bridge mode so it was a device on my lan. So it runs, finds dmr's and start airplay services. Bonjour does not find them. I can manually add them to Tuneblade. It trys to connect, but fails. The log output on the linux window shows tuneblade did try to connect.

[jer1956]

P.S. I then tried to install the plugins into windows python the same way. It failed due to the missing function getifaddrs, a linux only function.

Full level 4 log twistd.log

[provegard]

As far as I can see from the log, airpnp is up and running, is detecting UPnP devices and is accepting AirPlay commands.

Please note that there is no RTSP support in airpnp.

[jer1956]

From what i've read Airplay uses rtsp for "in use" interrogations. Hence why tuneblade starts with rtsp. Tuneblade works with my actual airplay devices. http://nto.github.io/AirPlay.html#audio-rtsprequests

So in essence this is for video only via http?

[provegard]

Yes, that's the use case I developed it for. Basically controlling my WDTVLIVE from an iPad/iPhone. I actually have a UPnP audio device so I thought about RTSP support, but I never got around to implement it - partly because said audio device has a buggy UPnP implementation.

[jer1956]

Don't get me wrong. This is a very clever idea that has room for improvement. You have issues yourself with detection. Is that because it has no bonjour code? I had the same problem with my Yamaha amp. My IPAD cannot find it. But with tuneblade i can manually put in a device using it's IP and controller port. So ironically i can only use it's Apple feature via a PC!

[jer1956]

Trying to get this working forced me to use Linux in a Virtualbox. I have found another linux tool. Pulseaudio-dlna. I will focus on trying that. Thankyou for your time

[provegard]

No problem! I hope you'll find something that works. :)
