[HDHomerRun] Stuck scanning for channels

[QuiteConfused]

Hello and thanks in advance for any help you can provide!

Currently I'm moving from a setup with MythTv with a legacy HDHomeRun HDHR (2 tuner) to using Docker on Debian 12. I'm able to see the two tuners in Settings -> Devices, but clicking "Scan channels" on tuner XXXXX-0 leaves me on a screen which is stuck and says "Loading EPG mapping". I'm using Schedules Direct for ATSC, and I was able to successfully login under Settings-> Guide.

My Docker compose file:

Code:

version: '3.3'
services:
    nextpvr_amd64:
        container_name: nextpvr
        volumes:
            - '/home/kirchman/docker/nextpvr/config:/config'
            - '/mnt/recordings:/recordings'
            - '/home/kirchman/docker/nextpvr/buffer:/buffer'
        restart: unless-stopped
        environment:
            - HOST_IP=192.168.1.67
        ports:
            - '8866:8866'
            - '16891:16891/udp'
            - '8026:8026/udp'
        image: 'nextpvr/nextpvr_amd64:stable'

HDHomeRun FW is version 20221023

ATSC epg scanning is only supported on Windows. Other options are shown on the wiki

Then I'm a bit confused about how to add channels. The Web UI says to add channels from Settings->Devices. But selecting my tuner on that page only shows a button to scan? That same button which I mentioned does a ATSC EPG scan. Is ATSC live viewing not supported on anything but Windows?

I've looked over the wiki, but I don't see those limitations listed anywhere.

Edit: Receiving epg from Schedules Direct is also Windows only? Since I've logged into to SD in NextPVR and added ATSC EGP frmo there, shouldn't the channels page populate?

[mvallevand]

NextPVR doesn't scan HDHR devices by frequency. Instead it uses the HDHR API to load the saved channels on the HDHR device. https://info.hdhomerun.com/info/using_th...y_hardware I do feel his can be a bit awkward for non Windows users who may never have saved any so yes a real scan would be preferred if sub ever has the time, remembering that legacy devices are quite old now and ATSC 1.0 has been sunset.

Schedules Direct is supported on all platforms. Best to automap by channel number. Upload the zipped logs of is is failing

Here is a wiki link you missed https://github.com/sub3/NextPVR/wiki/EPG.NorthAmerica

You didn't open up all the UDP ports in the instructions that could cause some problems

That fixed it! I did a scan using that Windows Setup Utility long ago, but rerunning it caused it to find all the channels when I went back under Settings->Devices then scanned using SD.

• So now my channels are populating and I see my EPG data from SD. But when I try and stream from the tuner in NextPVR, FFMPEG in the logs reports that there is "Invalid data found when processing input". I should mention I'm only using CPU transcoding right now
  

• And which ports are those that need to be open? [url]https://github.com/sub3/NextPVR/wiki/Install-Docker[\url] only lists [code]--publish 8026:8026/udp \[\code]
  

For the record, it doesn't stream in Kodi either, even after installing kodi-pvr-nextpvr

I tried recording a show, but it says it failed. "[Failed: No errors, but no data delivered. This is usually because the device failed to lock a signal.] ". Logs included in second zip file

[mvallevand]

That's a bogus message see the legacy instructions https://forums.nextpvr.com/showthread.ph...#pid522449 here looks like the wiki needs an addition for legacy devices.

[QuiteConfused]

Yes! That was it. Thank you very much

I'm not going to critisize what volenteers prioritize, but the FCC has mandated that all stations maintaiin substantialy equivilant service on ATCS 1.0 until June 2027, and LG's 2024 models still don't have atsc 3.0 tuners. So 1.0 tuners are far from out dated.

ATSC 1.0 is supported in NextPVR, and not going away anytime soon. (We'd prefer ATSC 3.0 doesn't take hold)

Some of the ATSC 1.0 HDHR devices are older than others though, and the really old ones were quite basic, and you need to do a few extra steps to get them working correctly. Newer ones (with TCP support and built in web interface etc) are more straight forward for the user to setup.

Understood, here in Canada we don't even have ATSC 3, Silicondust certainly don't consider the number of homes a commercial priority.

That being set I did write a utility today to see if I can do this from the command line. If you could zip up the the output from and hdhr_config scan I can see if my utility works, I don't have any channels with multiple frequencies to test.
