NextPVR + HDHomerun no channel Mux setting

[ozra]

Good Evening,

I have just discovered and setup the latest NextPVR on Linux on a VM.
Install was a breeze and it all worked from the start.

Thank you so much to everybody that has made this software possible.

In Australia on DVB-T all of our stations are muxed with multiple channels on the same frequency.

My Problem:

Coming from TVHeadend, I can't seem to group or enable configuration of the channels that are on the same Mux to record more than one show on the same Mux/tuner.
I can tune all channels individually without a problem.

With my HDHomerun I can record two distinct channels. (Dual Tuner)

I cannot seem to find any info or settings (apologies if I have missed it) whereby I can enable the Muxes so that I can record two different shows simultaneously on the same mux and single tuner instead of across two discrete tuners.

Does anybody perhas have some advice for this noob?

Thanks very much in advance.

On Windows, you need to be using the BDA device type for the HDHR and not the HTML device type to simultaneously record multiple channels from a single mux ... You need to install the BDA drivers on Windows ... That's pretty much everything that I know about HDHR devices and I don't know what the equivalent to BDA is on a Linux machine ... It might be that the HDHR doesn't do what you want on Linux.

Thanks for the reply.

I guess my question stems from running TVHeadend Server on a RaspPi and it worked there. (B+ On Raspbian OS)

From my browsing it seemed the RaspPi is not up to the task on NextPVR, thus my VM on ESXi with 4 cores etc and Ubuntu for NextPVR. (Browser Playback now works as opposed to failing with RasbPi)
I am not up to scratch with all the capabilities of NextPVR though so thus my question.

Depending on the device there could be two modes, HDHR and DVB-T HDHR modes won't work with multi-rec (multiple muxes)

The RPi server is really better with direct play clients like Kodi.

Thanks Martin,

The device (HDHomerun) is fine and works with multi-rec (multiple muxes) as proven by a different server. (Actually two: TVHeadend Server (on x86 and RasbPI - for low power usage) and MythTV server (on X86))

My stumbleblock is how I can enable that functionality on NextPVR Server on Linux (x86).
More interested in a solution than the platform.

Frontends are a variety of Kodi clients on x86 and Pi. Only using (Win10) Browser playback to test installation and configure.

Looking at my regular and legacy Silicon Devices they both show HDHR mode which is odd because the legacy device doesn't support http. I thought the legacy devices needed rtp mode. They do have multi-rec in that that the same mux can be recorded twice for padding etc but I don't know about multiple muxes since locally we don't have any. Yes it is possible, but I am unsure where sub is with this on linux.

Basically...

- NextPVR on Windows you can get multiple channels per frequency with an HDHomeRun with a single tuner (using the BDA drivers).
- NextPVR on Linux is limited to the HDHR mode, which uses http behind the scenes, and this is limited to a single channel per frequency.

http has been SiliconDust's preferred interface for the device for a few years now, and it's great for some aspects, unfortunately it doesn't allow multiple channels from the same frequency

It's not high on my priority list, but I may look into adding a different mode for linux, which allows multiple-channels-per-mux. This would probably show as an entirely different device type, since it needs to do a lot of things differently at scanning time.

It still shows up in NextPVR as "HDHR", which is normally http transport, but for these legacy devices it falls back to rtp for network transport.

Thanks Sub,

Appreciate the answer and the technical details.
