Plugin: SJQv4

[graywolf]

Try to learn this groovy but coming from 0 prior experience so a lot of trial/error adn guess work from other examples. Coming hard.

Wanting to have a test script to check if MF is currently being watched.
Found where MediaHelpers isBeingWatched would get me the value but no matter the umpteen different variations of trying to get that value, still getting errors.

Below is just 1 of my attempts. Will continue trial/error or someone helps show me the way out of this wilderness

/*
   Pretest if MediaFile is currently being Watched 
*/

String fileName = SJQ4_METADATA.get("SJQ4_LAST_SEGMENT");
boolean Watching = MediaFileHelpers.isBeingViewed(fileName);

if(Watching) {
	println("Is Being Viewed; return task to queue!")
	return 2 
} else {
        println("Is not being Viewed: executing the task now")
}

return 2

[graywolf]

ok...got past the errors but not getting correct results
import of the MediaHelpers resolved the errors

/*
   Pretest if MediaFile is currently being Watched 
*/
import com.google.code.sagetvaddons.groovy.api.MediaFileHelpers

String fileName = SJQ4_METADATA.get("SJQ4_LAST_SEGMENT");

if( MediaFileHelpers.isBeingViewed(fileName) ) {
	println(" is being viewed; Return task to queue!")
	return 1 
} else {
        println(" is not being viewed: executing the task now")
}

return 2

ok. on an HD200, I Watch Now a recording.
on an HD300, I assign the task to that same show. The test gives me " is not being viewed: executing the task now" instead of the expected " is being viewed; Return task to queue!" <sigh>

[graywolf]

Got it to work. Boy this is going to be a bit more of a learning curve than V3 was. But eventually will get it I guess.

/*
   Pretest if MediaFile is currently being Watched 
*/
import com.google.code.sagetvaddons.groovy.api.MediaFileHelpers

String id   = SJQ4_METADATA.get("SJQ4_ID");
String fileName = SJQ4_METADATA.get("SJQ4_LAST_SEGMENT");
Object mediaFile = MediaFileAPI.GetMediaFileForID(id.toInteger());

println( MediaFileHelpers.isBeingViewed(mediaFile) );
println( fileName ) ;

return 2

ok...next question and I haven't found the docs on the Class yet.

    ServerClient sc = new ServerClient();
    sc.scheduleMediaScan();

Is there a way to wait until the scheduleMediaScan completes?
Or is there a way to have a Task kick off when a scheduleMediaScan completes?

Also, where is the javadocs for Tools class?

Tools.setTaskResources
Tools.setExeArgs

No, this call is asynchronous. This method is there to prevent multiple media scans from being triggered at once. Let's say you were writing a script that moved a recording and then you needed to scan to have the core find the new location. Well if you were moving 15 recordings at once you wouldn't want to trigger 15 separate media scan threads on your system. This method schedules a scan for 20 mins from the first time it's called. Any other calls to this method within that 20 mins are ignored and so in the end you get just one media scan. It's a resource saver on your system.

Or is there a way to have a Task kick off when a scheduleMediaScan completes?

Not with the above method, but you can use the Sage API call directly:

Global.RunLibraryImportScan(true)

That call, with true as the argument, will run a media scan immediately and wait until it's done.

Also, where is the javadocs for Tools class?

Tools.setTaskResources
Tools.setExeArgs

They are here (the link is also referenced in the SJQv4 user's guide).

[graywolf]

Excellent. Got a logical flow of how the mods I want for the mv_media, just need to figure out the rest.

Just need to figure out how to get the new ID for the moved show once the Scan completes for post-move processing. I'm assuming the SJQ4 metadata values would no longer be valid after the move/scan.

Well I'm starting to understand a little about the javadocs and how to read them...at least I hope so.

If you are calling Global.RunLibraryImportScan(true) and waiting for it to return then you can get the new media file object by calling:

MediaFileAPI.GetMediaFileForFilePath()

Just create a new File object representing the new path of the moved file and pass that to the above method. It will return the new media file object. This only works if you wait until the media scan is complete.

[graywolf]

wonderful wonderful wonderful...you have helped save my blurry eyes.

that is exactly my intention.

I created a new thread, separate from this one, for sharing SJQv4 ideas and code. This thread rocks, but is more nuts and bolts. I am hoping my new thread will be for sharing ideas for SJQv4. Hopefully it takes off!

I am having an issue and am looking for some help. Some time ago I installed SJQ and played around a bit before uninstalling. Recently (yesterday), I decided to purchase a license for Slugger's plugins and want to give SJQ another spin. After installing the plugin from the Sage plugin manager, I went to web apps to begin to configure it. I see an app called "sjq" with version # 4.0.0.1426 and when I click on it, it gives me a "HTTP ERROR: 503 Problem accessing /sjq/. Reason: SERVICE_UNAVAILABLE" error. I tried restarting Sage and that did not fix it. I tried uninstalling and reinstalling SJQ and I still get the same results. When I click on "Configure Plugin" from the GUI, it tells me that the plugin is "Licensed". Anyone have any idea on what is going on here or how to fix it? Thanks.

sjq4v does not have a web component. There is an UI Mod plugin that you do the configuration from. See sluggers response to a similar question last week for more info

Thanks for the prompt response. I had a feeling this was addressed somewhere, but this is a rather daunting thread (although I have seen much worse). I will head over to the wiki and start reading. Thanks again.

Updated task client and SageGroovy builds are now available. This update simply updates the upstream jars used in these apps. Of significance, is the update to the gtools jar. This update adds many new extender device features that you can use from your Groovy scripts. Namely, there are now methods available to power on, power off, reboot and query the status of extender devices. These features were tested on HD100 and HD200 devices. I don't have HD300s nor MediaMVPs to test against. Rumour has it, the HD300s should work fine and the MediaMVPs probably not so much.

If someone needs/wants support for MediaMVP devices, they simply have to provide me telnet access to the device for an hour or two so I can test and tweak the code. Same for HD300 support, if it doesn't work.

A quick example of what you can now do in Groovy with this update:

import com.google.code.sagetvaddons.groovy.api.GlobalHelpers

println GlobalHelpers.powerOnExtenderHost('192.168.0.30')

Output:

true

That simple script will power on the extender device at the given IP address. There are various methods to power on, power off, reboot, and query the status of extender devices by IP/hostname or MAC address. There are also methods to help pinpoint the exact type of an extender device (MediaMVP, HD100, HD200, or HD300) with methods like GlobalHelpers.isMacAddrHD200(). There are caveats with all of these methods and those details are in the javadocs and should be read closely by all users prior to use otherwise you may be scratching your head when you don't get expected results.

Happy scripting!

EDIT: In case I haven't mentioned this before, the gtools.jar file can be used in Java code as well, since I compile that library to byte code. To use gtools.jar in Java, you simply include the jar on your classpath along with the groovy-all-1.7.10.jar plus the other dependencies my library code uses (sagex-api, commons-net, commons-lang). This library provides a lot of nice convenience methods, though if writing pure Java, the dependency on Groovy might be a little heavy for some devs (but well worth it if you like the convenience).

Have you issued the new licenses yet?

Slugger,

I've got an MVP and an HD300. Let me know if you want to test against them and I'll set it up for you. (Can't be today, I'm about the leave the house.)

Yeah, I'll email you some evening this week. I'm pretty sure the HD300 will work with zero code changes. The MVPs will need some tweaking, I'm sure.

I am not able to delete or modify a client. I have changed the IP address of the client in question (made it static), but I can't update it in SageTV. If I try to delete it, the GUI (on the server) hangs when I click yes to the delete it prompt.

If I try to modify it and enter the new ip address, after making the change in the pop up, and then trying to commit the changes, I get this error "Internal Error Creating new AgentClientClient"

On a possibly related side note, I am not able to SRE overrides in the GUI either, and get an error when I do that too. Something is awry in my Slugger world of awesome plugs.

I checked the logs, and dont see any errors in the logs.

Check your sagetv_0.txt log file for errors. This sounds like errors with the STVi. Get the log file and open a ticket for Tom to look at (he handles all things STVi).

An alternative would be to directly edit the database to make these changes. If you're unsure what you're editing in there, then stop and ask otherwise you'll foobar the SJQv4 db, but it's pretty straightforward. You'll want to edit the client table when you get in there.

Same thing here. Get the log file and check for errors, open ticket for Tom's review. In the meantime, you should be able to create/edit overrides via the web UI for SRE. If the web UI isn't working, then that's my department.

The Web UI for SRE works fine, so I will follow up with Tom for the SRE and SJQ issues.

I was finally able to delete and re-add my client (not sure why, but a reboot did the trick!), which I did before I saw your post, but thanks for the "Edit DB" trick.
