Need help testing something for PlayOn

[simonen]

http://192.168.1.2:54478 in my case, you can't use 127.0.0.1 or localhost, they seem to block that. IP should be whatever server your playon is installed on.

Ahh, I see it now. From their forums, sounds like they are trying to block access that. Makes sense, its a security hole and they don't want people downloading the streams, for that matter neither do I.

I imagine pretty soon they'll be doing browser ID checks to try and limit access to that to just the Wii Browser. That's an easy enough work around though as those can be spoofed, but if they feel enough heat they may just shut down the Wii support / web server entirely. The UPnP paths will prolly end up being much safer as

a) They are much harder to access and as such provide reasonable security via difficulty.
b) Its the UPnP standard so they're required for everything else to work.

But essentially we have the same goal: find a way to turn a list of PlayOn videos into a dynamic RSS feed so it can be used in Sage's Online Service menu without any modification to Sage.

Are you running the PHP / VB script via Nielms webserver? Also, are you able to do targeted sorting easily (i.e. just display one show's episodes)?

[simonen]

Basically it just brings the entire queue into one feed so it shows everything together. I have noticed that they are changing up the links to the files quite often, it use to be once per day, but I have had to update the static link references in my test xml file a few times in the last hour or else they stop working. So whatever we do must be fairly live.

In addition, it looks like Sage is also caching the feed, so if the links change you have to restart the UI or restart the extender.

I am using xampplite apache/php package. But I am not using the VBscript at the moment, that was a different option. I can send you that stuff if you want. Maybe you can take it to the next level since it is using the upnp.exe app.

Personally, I have no interest in downloading the files either; just want to watch them on a TV screen.

[evilpenguin]

I think the ideal next level is gong to be a Java implementation of UPnP.exe that we can turn into a servlet for Jetty. That way anyone who's running the Sage Webserver can run this also with zero extra config.

[simonen]

Really the ideal thing would be for Sage to add a UPnP browser to the software in their next version and then we would not be limited to the user queues or even playon for that matter IMHO.

That's exactly what I have been saying!

There is some value to downloading the streams.. I use linux, and run playon in an XP VM. My CPU is an AMD 4850e, and playon running in a VM on this box cannot quite keep up in realtime.

The first thing I tried was to mount Playon's UPnP feeds via djmount (like the HD200 does) and "browse media files on server" from my HD100, and browse to the right file and play it. The browsing took forever, and playing the file was totally unreliable.

The second thing I tried was to rsync the shows I was interested in from the djmount to one of the sagetv media directories. This almost worked, but the playon VM was too slow, and I'd see shows where there were lots of problems (like the same frame repeated for 30 minutes).

My current kludge is to

- mount Playon's UPnP via djmount's playlist option, which gives me a url to wget for the actual .mpg file:

% djmount -f -o playlists,default_permissions,allow_other /tmp/dj

- download the file I want

% wget -O w13_s1e12.mpg `grep http /tmp/dj/PlayOn\ \(playon\)/Hulu/TV\ Episodes/W/Warehouse\ 13/s1e12:\ MacPherson.m3u`

- Then rescan imported media in sagetv.

This is totally manual, but at least I can watch Hulu on my HD100. I've been meaning to try to automate it..

One thing to keep in mind if/as you develop a plugin is that it would be nice if there was a way to run the PlayOn server on a separate box from the Sage server. It seems like a goofy thing to do, but my Sage server (presumably) doesn't have enough power to do the transcoding for the PlayOn server, by my workstation has plenty of spare power. So, since I'm not ready to upgrade my Sage server, it'd be nice to run PlayOn on my workstation for a while.

No worries, UPnP.exe gets all its info over the network so you can run it on any PC. It might even run via Wine on a linux box.

Basically, my plan for weaponizing this is to make crank out a program that turns UPnP into a compliant Podcast feed. Then drop that into a webserver's cgi-bin folder would allow the creation of customizable URL's which could be feed though Sage's mediaRSS framework.

Great! I'm looking forward to trying this out. Thanks for working on it.

So what kind of PC horsepower does Playon require? My Sage Server runs WHS which has only a 20GB C: drive. Another PC on the network I could use to run Playon is a P4 3GHz, but as i read their website is too slow. Any tips on how to run Playon on my WHS (quad core) and not install to small C drive?

[Zippster]

According to their site, they are going to be coming up with some sort of update to allow specifying usage besides just your windows drive, hope so as mine is only 20 GB because OS is all it holds.

My Sage server I just installed playon onto is dual opteron 2.0's , Sage doesnt ever use much of anything, running one Playon show ( to Xbox 360 ) though is using about 59% They also claim to be coming out with optimized updates to help CPU usage.

Cant wait to get this on to my extender though.

EXCELLENT work EP.

Not for me:

% wine z:\\tmp\\upnp 
Can't locate Win32.pm in @INC (@INC contains: .) at -e line 762.
BEGIN failed--compilation aborted at -e line 947.

If this is perl, maybe you could just publish the source?

someone get Jeff/Narflex to see this thread, he might cook something up for the next beta.

Hmm, yeah, its a compiled Perl script, but it should have all the libraries it needs packed into the .exe. But, then again, i'm not really clear on all the voodoo that goes into compiling perl scripts into executables so its not surprising that it wouldn't work. But, still no worries, as I should be able to compile it into a linux executable also. Here's the source code btw,

http://mediascraper.svn.sourceforge....st.pl?view=log

[simonen]

Houston, we have liftoff! Hulu user queue as an online feed is now a reality. More to come later today, and I need to figure out where to post the files for people to grab.

There are 2 parts. A vbscript that you can schedule to run however often you wish, must run after a restart of your computer though. The script also uses the upnp.exe app. The second part is a php script that translates the output of the upnp.exe app into an rss feed.

Excellent news! Keep us posted.

Hmm.. something is not quite right. I downloaded the script, and changed the shell interpreter to #!/usr/bin/perl, and it almost works. I tried some of your examples at the top of the thread. The first problem is that the *nix shell hates the " syntax you have (complains of mismatched quotes).

- I tried escaping them (./UPnP2Podcast.pl \"\"Hulu:TV Episodes:+2\") which gives me the usage mesage:
UPnP2Podcast v1.0beta
USAGE: UPnP2Podcast.exe (UPnP Search String)

- I tried putting a single quote around all of them. That works better, but doesn't find the server:

./UPnP2Podcast.pl '""Hulu:TV Episodes:+2"'
Error! Couldn't find UPnP Device: (""Hulu)

If I run strace, I see it found my playon server, but failed late. Eg:

It is worth noting that djmount also makes those same complaints about 404s from http://172.31.193.172:52478/. But it works:

$ ls /tmp/dj/PlayOn\ \(playon\)/
Amazon VOD (Beta)  CBS  CNN  ESPN  Hulu  Netflix  PlayOn Info  Revision3  Syfy  YouTube

I don't know enough perl to know whats failing, or why..

Drew

[aflat]

take a look at the qn function in perl, it should solve most of your quoting issues

[evilpenguin]

Sorry, I forgot to mention I updated the program to not be hardcoded for PlayOn anymore, now you have to specify it.

./UPnP2Podcast.pl 'PlayOn:Hulu:TV Episodes:+2'

Also, I made some modifications to the Net::UPnP .pm files so i'll have to post those as well. It'll work without them, but with them it can grab tons of extra metadata for the files.
