API call for Recording Complete

Sun, 19 Jan 2025 13:04:53 +0000

Apologies if this has been brought up before. Have searched around the forum as well as done a quick Google but can't find much for what I'm looking for. Close or redirect me if this is inappropriate.

Is there a specific API call for when a recording is complete or some kind of config file / flag that's changed when this occurs? I'm wanting to develop *something* that gives a notification around the status of recordings. The WebUI knows the status, so I imagine the information is stored somewhere.
Lastly, I see in most threads about the API that it's previously never been documented. Is this still the case in 2025? Even if there is a vague / incomplete list of calls it would save some time, but obviously no worries if not : )

Extra overriding #EXT-X-KEY wishlist

Wed, 08 Jan 2025 01:07:11 +0000

I am trying to write an extra that involves sending back an m3u8 containing an AES key

#EXT-X-KEY:METHOD=AES-128,URI="...",IV=0x30303030303030303030303067020c0b,KEYFORMAT="identity"

but unfortunately the URI requires two cookies and some headers.

I haven't been able to make NextPVR accept passed cookies and I am not sure if NextPVR uses passed headers either when it fetches the key either, I couldn't see any logging on getting the key.

My first wishlist is that cookies could accepted from Extras (I and guess m3u8 files), perhaps using the Kodi method opf muitiple Set-Cookie= pipes on the url. These are huge though and in my use case only needed for the key.

My second wishlist which might be easier is providing an option allowing a override the URI. The extra could write the key to file and NextPVR could use that files instead of the URI to get the key.

Manual recording API

Thu, 09 Nov 2023 00:39:18 +0000

I am trying to schedule a manual recording for a show in Kodi. Is there a way using the API to keep it manual if I provide a name? In this case my 2hr recording is being truncated to one hour.

API channel.stream.start

Sun, 07 May 2023 19:31:33 +0000

Sub after channel.stream.start either fails or has a client based-timeout should the client be issuing a channel.stream.stop in either or both cases?

FM tuner support in NextPVR?

Wed, 23 Nov 2022 06:43:42 +0000

Does any version of NextPVR support FM tuners?

I am using a WinTV-1800 PCi-E x1 card with an FM tuner on Windows 10, but I use Ubuntu also.

I tried versions of NextPVR, including the old 4.2.5 version, and it doesn't seem to support the FM tuner.

At least some versions of WinTV software and also the VLC media player (using DirectShow) support the FM tuner.

IPTV like stream from Sound Card input - FM Radio Project

Sun, 20 Nov 2022 14:50:03 +0000

Hello,

I'm wondering if anyone can offer a bit of guidance on this one. I am working on a project to make an FM radio tuner input for NextPVR, but in an effort to keep it simple I'm intending to make it look like an IPTV device. Maybe best if I describe the idea first.

What I'm trying to achieve is something similar to NextPVR's own method of http://nextpvr:8866/live?channel=1 , such that a channel (frequency) can be requested, and the response is an MPEG-TS stream. I believe that NextPVR is using VLC to create the stream?

I am using a Raspberry Pi with an FM radio tuner IC attached to it (Si4703). The R Pi will listen for http requests formatted in such a way that the URL requested contains the frequency the radio IC should tune to. I have this part largely working as expected. For example, tuning to http://radio-pi:80/freq=878 tunes to 87.8 MHz.

The output of the FM radio IC is line level analogue audio, and I am feeding this into a USB soundcard. I can run FFMPEG to capture this and create an MPEG-TS stream, and listen to this using VLC on another computer.

I'm wondering, can anyone give me guidance on how to respond to the http request with the MPEG-TS stream? At the moment, the URL request just sends back a very basic HTML page. I am familiar enough with starting another program from Python, but how do I redirect the output of FFMPEG back to the client making the tuning request?

I'm programming in Python. I'm happy to switch to VLC on the server to create the MPEG-TS steam (or any other tool) should there be an easier way to crack this nut!

Thank you

PIP plugin for Kodi

Sun, 16 Oct 2022 05:01:16 +0000

I came across this Kodi addon for PIP mode:

https://github.com/mltobi/kodi-pip-addon

Looks like it's designed for tvheadend as the backend, but it has a creative approach that we may be able to adapt for NextPVR.

ScheduleHelperFactory

Thu, 13 Jan 2022 19:55:03 +0000

Is ScheduleHelperFactory.GetScheduleHelper().ScheduleRecording(e, RecordingQuality.QUALITY_DEFAULT); supposed to respect the duplicate flag or is that in program control?

How do NextPVR web and UI clients determine that the Original Air Date year gets appended to the title (assuming not from Schedules Direct)

Video streaming URL and parameters?

Fri, 22 Oct 2021 18:48:17 +0000

Can someone point me to the API video streaming URL for both recordings and live tv as well as the possible parameters (transcoding, direct, etc.)? Thank you.

Disable stdout

Sun, 29 Aug 2021 16:01:29 +0000

Can NShared/NUtility be configured not to output to stdout without doing it globally? I am working on a C# Extra that talks to NextPVR and I want to avoid things like

NEXTPVR_INSTALLDIR C:\Program Files\NextPVR\
NEXTPVR_DATADIR C:\Program Files\NextPVR\data\
NEXTPVR_DATADIR_USERDATA C:\Users\Public\NPVR-data\

and other unknown/unwanted strings from going to stdout.

Invalid session?

Sat, 24 Jul 2021 22:14:50 +0000

Hi I am trying to get the EPG data from this URL
http://127.0.0.1:8866/services/service?m...gs.current

but it gives this response

This has only happened after I updated to version 5.1.3.210711. Is there any way to fix this?
I have ticked the options for Allow remote access/Allow unauthenticated access (this is only accessed locally).

StoreMetaData

Sat, 10 Jul 2021 15:40:48 +0000

Is there a technical reason the RecordingsService.StoreMetaData is not available via RecordingsServiceProxy? I'd like to use in in my NextImport to dump the xml file so I can edit it and then update the event_details field. I prefer using API functions over hardcoding database and xml writing.

The reason I want to do this is the season finale of Clarice didn't include the S/E information with the metadata. I'd like to use the XML file as the input for an update, editing that field in the database is cumbersome.

Lease Renewal

Thu, 22 Apr 2021 16:00:59 +0000

I am working with live TV and would like to know how the lease renewal mechanism works. In particular, does this "handshake" involve the device providing live TV? What messages, if any, are exchanged between the NextPVR server and the device?

Tried searching with Bing but got nothing relevant.

Thanks
