I'm glad there are more and more people helping out on this one, we might get somewhere! I gave listening on port 80 a try but it can't connect to the socket, even when I'm starting the client as sudo.
Last week I gave multithreading a try, the idea behind it was to create two web.py servers whereof 1 listens to the incoming requests on port 3000 an one on port 80. But I didn't get the second web.py server running. Also tried to manually create sockets, this also returns in an error. This code is in my development branch that's isnt pushed to github atm, if someone is interested in this idea let me know then I I'll push it to github.

I have attached some code that listens on two ports and gets the command and arguments from the request which I hope you find useful. I am hoping that just adding your zeroconf and xbmcCommands class will work, I'll try this evening.

(warning I have not used python before so the code may not be ideal :) )
103


That looks great! Will take a better look at the code tonight and try to implement this into the script.
104

Looks like the second port is actually 9777 UDP, using the XBMC Events protocol for most buttons (including play, pause, etc). I’m working on some code now that spawns a second thread that listens on the UDP port and calls functions accordingly. It’ll be available soon at:



105


keep us posted! I'm too busy with other stuff that has to be done to even think at coding tonight.. :(
106


looking forward to get the newest data :)

Currently have what appears to be a mostly working client, but with some significant changes to the original code:


Using the tornado websever, instead of web.py (install via sudo pip install tornado ). Web client is in a new thread
-- This allows for having a seperate thread managing the web requests

Using a new thread for a UDP listener

Both threads now use a shared queue (Python Queue class) to queue up commands, and the main thread handles the queue entries.

Awaiting some testing (GF is using the TV my pi is attached to), but everything seems to be working running from the command line. Will push to github once it tests OK.
108


This sounds awesome! Can't wait to test and look around your code and learn from it :)
109

Well, the code’s posted, still just as “untested” as before, but you can go ahead and take a look at it.



It’d likely have a large number of problems, but the udplistener class does seem to work correctly.


110


I looked at your github page but the only file changed is the readme file. Did you push all changes to github?
111

Try that again. havent used git in such a long time, been ruined by cvs/svn at work. Always forget to push now.


112


Thanks, new files are there. I don't see any changes to pyplex.py. Is this correct? I only skimmed the code (It'll take a while before i'll have the time to code after office hours) but am i correct when i think that in order to use your new implementation pyplex.py must be updatet to use them?

thanks for the awesome work!
113


Ach! forgot git doesnt autocommit files if you dont list any. Just did a commit -a and push.

Also, just did some testing, play/pause and stop are working great. Still putzing around with getting HDMI and audio to work on my test file.
114


This sounds awesome! To bad i really have to go to bed now, otherwise i would have played around with this for the couple hours :P
115


Is it a special test file? My sound works great with hdmi.
116

Its a breaking bad episode. Looks like its probably setup related, not script / player / hardware related. I’ll have to check out the rest of my hardware later to see why my audio is not working.



Anyway, my github repo should have a pretty good working client.

117

Audio working well for me, tried a couple of files and playback works :slight_smile: However the controls don’t seem to be working for me. While trying to figure it out I put the following debug messages in the Pause def.



<br />
    def Pause(self, message):<br />
        global omx<br />
        if(omx):<br />
                print "Have omx"<br />
                omx.toggle_pause()<br />
        else:<br />
                print "No omx"<br />


I get the following while trying to pause:


<br />

I can see omx is a global variable and it it is set PlayMedia, so don't know why it is failing for the commands. Any ideas?
118


The line "Command PlayMedia not implemented yet" means there was an exception while calling the command, so omx probably did not get set (if the exception was above that line).

I'm going to do a few mods to make exceptions more visible in a few minutes, I'll post back when I can.
119


There's a new version on github, the only change should be it'll make exceptions within the command handler much more visible. I havent tested it, but its a pretty minor change, I wouldnt expect any more breakage.

When I start a movie, i get the following exception: (with the new pushed data - before it was perfect)

The film runs but the sound freezes. It starts, stops, starts, stops. I think you know what I mean :)
