Jumpy Plugin (17 May 2013)

[infidel]

Jumpy (Java Underlay for Modules in PYthon) is a framework for scripts or other external processes to plug into UMS or PMS, primarily to

• add folders and media items to the xmb.
• act as user-defined external players.

The API is accessible from python via jumpy's python module, or from other languages via system calls. Interaction is through a localhost socket managed by py4j.

Jumpy began with my having grown tired of occasionally poaching stuff 'by hand' from xbmc addons for use in PMS, and deciding to see if I could mock the xbmc plugin API itself so as to run these addons under PMS as-is. The result is Jumpy plus jumpy-xbmc, an included set of python modules to 'jump' the xbmc addons.

Jumpy-xbmc works with most xbmc video addons: Hulu, Free Cable, Al Jazeera, PBS, Academic Earth, YouTube, and many more. Addons are 'mostly' functional in the sense that all content is shown but interactive features that require user input are inactive.

Jumpy itself is general-purpose, of course, and you can use it to plug your own scripts/commands, python or other, into UMS/PMS as well.


Jumpy-0.2.7 - 17 May 2013

• new OS-X .app auto-installer.
• better localized text support for non-English languages.
• implemented late-resolving media items (credit goes to SharkHunter ), which reduces folder-depth on the xmb and groups media items better.
• automatic support for the new UMS url resolver functionality via the xbmc and youtube-dl url resolvers, see the docs and also:
  
  • Linux/OS-X users: there's currently a bug in UMS which prevents playback of these resolved urls. A temporary fix is here.
• a few api additions
• jumpy-xbmc:
  • now slightly faster and more robust (hopefully!)
  • more bugfixes resulting from user feedback (thanks!)
  • improved support for the xbmc api.

Download and unzip to your plugins folder, or better yet see the Quick Setup.

Note: when reporting bugs please set logging to TRACE and attach UMS.conf or PMS.conf + debug.log + jumpy.log + jumpy-scripts.ini + PMSencoder.log together as one zip file (or use either the Pack debug files button on the UMS Traces tab or DbgPack plugin in PMS).

Hello,

Thanks for the excellent work with Jumpy! I've used it successfully several times to access my XBMC plugins via PMS. However, I've struggled a bit to get it configured to successfully view shows via the Veetle XBMC addon. I do understand that the original veetle plugin in XBMC had some playback issues over the past 2-3 months due to veetle site changes, and those have been patched, as I have my local files. I am able to successfully view video content using XBMC and the veetle plugin directly. However, when I go to Jumpy to get to the veetle plugin, I can browse to things just fine, but all links fail to play and eventually generate an error in xbmc. One might ask why I would play veetle content when XBMC plays it fine... it has to do with streaming the content to my various devices that support upnp, but do not support xbmc. In any case, it looks like there is an error in the logs dealing with ffmpeg.exe not sure if that is the culprit or not. I've removed all associated programs (python, jumpy, xbmc, etc.) and reinstalled all, using your installer. The only thing I've had to change in the config is to point to the correct folder where xbmc program files reside (on my d: drive vs. c: drive). I'm attaching the pms_dbg.zip, with xmbc log file included in the zip as well. Thanks in advance for your assistance in troubleshooting and resolving the issue!

Best Regards,

Hi Madman_X,

The fix you're using for veetle in XBMC (patched avformat-52.dll) can't be used as-is in UMS because it's specifically compiled without ffmpeg support (even though it's a part of ffmpeg to begin with. If it had ffmpeg support it would in theory be possible to drop it into a dynamic ffmpeg build which could be run from UMS).

EDIT: this fix is no longer necessary as of jumpy-0.2.6

Luckily the second solution (veetle proxy) in the xbmc forums seems to work nicely in both Windows and linux:

• Unzip veetle-proxy.zip to your xbmc addons folder.
• start xbmc and make sure veetle is working.
• with xbmc still running, restart UMS.
• veetle links in jumpy should now be working (via the proxy server running in xbmc).

It's also possible to run the proxy without xbmc:

• Add a section like this to your jumpy-scripts.ini, substituting the correct path to your xbmc user folder:

  Code: Select all

  [+veetle proxy]
cmd = cmd /c start python C:\Users\[username]\AppData\Roaming\XBMC\addons\plugin.video.veetle\akamaiSecureHD.py


• restart UMS. The proxy should pop up running in a command console.
• you'll need to manually shut down the proxy by closing the console whenever you stop UMS.

Note that there can only be one instance of the proxy running at any time, otherwise things will get screwed up.

It would also be possible to build a patched ffmpeg, since the patch (to libavformat/flvdec.c) is trivial, but it doesn't seem worthwhile since the underlying cause appears to be that veetle has made arbitrary changes to its stream headers, which it could change again at any time.

Great! I will hopefully be done with our plugin interface soon so you can add this to the Plugin Installer too

Looking forward to it SubJunk .

Jumpy is a little installer-unfriendly in that it needs download+unzip+launch capabilities to set up properly. It already comes with a Windows auto installer (just a batch file running via self-extracting exe) which does all this, but it needs to run with UMS offline due to file-locking and also the fact that it writes some settings to UMS.conf. Offhand, I'm not that keen on rewriting all this as a custom java stub, but maybe your revised interface already takes care of some of it?

[Madman_X]

Hi Infidel,

Thanks for the detailed response. I tried both of your options for getting Veetle back up/running with Jumpy and both work great. I'll probably go the route of the script though since I don't generally use XBMC on my windows machine except for testing and installing the addons for use with Jumpy. Really appreciate the reply... I worked on this for a couple of hours and had just decided to ask for help...glad I did!

Hi infidel

Nice to see you over here
You've been productive I see. Maybe I should do a crack on jumpy again...

[infidel]

It's got plenty of cracks already, thanks .

Sorry to bring back a thread from the dead. My post was deleted and I was told to paste it here, so sorry.

I've attached a zip with all the UMS debug stuff (plus PMSencoder).

I can watch XBMC on my computer just fine, and i can watch some of the add-on's (like penny arcade) through UMS on my TV. I can't however watch twitch on my TV. I can load it up, choose favorites, click afolder etc until i get to a video stream. I click it and it stalls for a second and i get a 80028E1 error on my screen and a return err code 255(used to be 1) in UMS trace.

EDIT: copying and pasting an rtmpdump into C:\ changed the code back from 255 to 1.

No need to apologise, this is the right place. Political refugees are welcome .

I can't however watch twitch on my TV.

For the new twitch temporary fix see the following post.
