The situation here is that network programming for CBS is leaving the channel it has been associated with forever and is being moved to a new digital sub channel (XX.4, for example) of another local channel that has always been associated with another major network, and it is this new digital channel (XX.4) that I need to add to the program guide.  When the new channel was activated, my TV and the HDHR guide both picked it up immediately.

Using the web browser interface for my NPVR server, I went into settings and selected the devices tab.  I selected one of the two HDHR devices (which currently shows the 35 channels I have selected for the guide), and clicked the "scan channels" button.  In the guide selection I picked (as I always have) the Schedules Direct local broadcast listings for my zip code.  The results were a total of 30 channels, a few of which are among the channels I currently have selected, most which are not currently selected.  The newly created XX.4 channel does show up the scan.  At this point I cancel out because I'm unsure of what to do.  As I said, I don't want to screw up my current configuration.

If I select only the new XX.4 channel from this scan list, will the new channel be added to my currently selections, or will the current selections be erased and only the new channel show up in my channel choices for the guide?

Thank you in advance for your help.]]>

1. scheduled recordings are broken, I keep getting [Failed: HDHR stream not available]
2. When a TV show that I'm watching gets to the end, it stops and drops to the TV guide instead of playing the next show.
3. I can't get rid of the Silicondust EPG. The trash icon turns red when clicked, but nothing happens.
4. I have the timeshift setting at 120 minutes and the Ubuntu 24 memory leak occurs when a channel is left on for a day. Eventually the PC reboots due to "OOM" out of memory. I installed a dynamic memory manager "swapspace", which showed that virtual memory was getting over 300GB, dotnet appeared to be the issue.

I'm having an intermittent transcoding issue with NextPVR on Ubuntu 24.04 using VAAPI hardware acceleration. Most transcoding attempts fail, but occasionally they work without any changes.

Intel® Core™ i5-7500T CPU
Driver version: Intel iHD driver for Intel® Gen Graphics - 24.1.0 ()

I've verified permissions on /dev/dri/renderD128, the nextpvr user is in the video and render groups, and vainfo reports VAAPI support.
I've attached my latest logs (zip), which include both successful and failed transcoding attempts.
Any ideas on what I should check next?

Summary
I am running the latest ARM64 Docker image of NextPVR on a Raspberry Pi 5.
The DVB-C scan succeeds and channels are imported correctly, but Live TV and recordings always fail with:

Code:
No tuner was available for the requested channel.

The DeviceHost logs show:

Code:
Failed to get tuning params for (...) from /config/adapterX-DVB-C-channels.conf

The file is either never generated by NextPVR or the DeviceHost expects a different format than the standard DVBv5 tuning files.
Environment

  • 8 GB RAM
  • Hauppauge WinTV-dualHD (dual DVB-C/T/T2)

DVB Devices detected
NextPVR detects both tuners correctly.

Code:

Both are shown as

Code:
Present = true Enabled = true

Driver

Code:

Kernel modules load correctly.
After reboot there are no I²C errors anymore.
Signal
Signal quality is 37dB.
Example:

Code:
C/N = 37.5 dB

DVB Utilities
Code:
dvbv5-zap
Tunes correctly.
Code:
w_scan
Works.
It finds over 220 TV services.
Code:
channels.conf
is generated.
NextPVR Scan
The channel scan succeeds.
Example from device log:

Code:
Scanning 474000000 Scanning 482000000 Scanning 490000000 Scanning 498000000 Scanning 506000000 Scanning 514000000 Scanning 522000000 Scanning 530000000 Scanning 538000000 ...

Channels are found and imported.
Example:

Code:
Arena Sport 1 HD Arena Sport 2 HD Arena Sport 3 HD Pink Kids BN 2 TV ...

Around 220 channels are imported.
Problem
When starting Live TV:

Code:
No tuner was available for the requested channel.

nrecord.log

Code:
checking: adapter1/frontend0 enabled and present has channel live tv is possible

NextPVR launches DeviceHost correctly.
Example:

Code:
DeviceHostLinux -listen:39823 -type:DVB-C -device:"adapter1/frontend0"

DeviceHost receives:

Code:
<tuning>   <type>DVB-C</type>   <name>Arena Sport 3 HD</name>   <locator>     <conf>514000000OFF</conf>   </locator>   <service_id>2320</service_id> </tuning>

DeviceHost error
Immediately afterwards:

Code:
Failed to get tuning params for (Arena Sport 3 HD) from /config/adapter1-DVB-C-channels.conf

Then:

Code:
HTTP 404

Finally:

Code:
No tuner was available for the requested channel.

Important observation
Originally there was no

Code:
adapter0-DVB-C-channels.conf

or

Code:
adapter1-DVB-C-channels.conf

inside
Code:
/config
.
The DeviceHost still expects them.
Experiments
I manually created

Code:
adapter0-DVB-C-channels.conf adapter1-DVB-C-channels.conf

using:
  • DVBv5 format
  • frequency sections
  • standard NextPVR tuning format
Examples:

Code:
[514000000OFF] DELIVERY_SYSTEM = DVBC/ANNEX_A FREQUENCY = 514000000 SYMBOL_RATE = 6900000 INNER_FEC = NONE MODULATION = QAM/256 INVERSION = AUTO

Parser accepts the syntax (no parsing errors),
but DeviceHost still reports:

Code:
Failed to get tuning params

which suggests it expects a different internal format.

Should NextPVR automatically generate

Since scanning succeeds and
Code:

works perfectly, the tuner and driver appear to be functioning correctly. The failure seems to occur only when DeviceHost attempts to resolve tuning parameters for live streaming.

Just upgraded to version 7.1.0.260607 which fails to find any sat>ip channels from my Triax TSS400.  The log file shows a problem with paths.
I have included the log file which also contains an updated '1600 KoreaSat6 FTA (160.0E).ini' which reflects the updates made to freeview NZ satellite in the last week or so!
Please let me know if I can provide any further information

Kind regards, Stephen

I've tested it using dvbv5-scan and a 30 sec timeout and it does then scan the channels OK.

The issue isn't signal strength as the other frequencies are a similar or even lesser strength, it just seems that the service on the problem frequency is slower to enumerate(?).

TIA

I have a AVM Fritzbox cable router which provides 4 IPTV devices. Nextpvr finds all four devices correctly. In the past with NextPVR version 6.x scanning for channels worked very well, but now after I had to re-install my server the NextPVR scan fails (version 7.x). The port 8866 is set correctly.

When scanning the German Full Cable Spectrum (6.900MBd SR, QAM 256) the letters [PAT] [PMT] [SDT] [BAT] do appear from time to time and my Fritzbox GUI in parallel displays that a client is watching a certain TV channel, but none of these channels gets stored by NextPVR - so the list remains empty and NextPVR finally shows "0 channels found".

Attached you'll find the logfiles.

Any ideas?

Thanks a lot in advance!

Thanks to AI, I have step-by-step instructions from the Internet that I used to install Comskip with (using) my Linux Debian 12 Synaptic Package Manager.  I have ATTACHED these instructions for others to use, and comment if they are flawed or inadequate.    The Synaptic Package Manager did not throw any errors during the Comskip installation.

I was very careful to be sure all the required dependencies are installed before and after the installation.  A sample of the dependencies I found installed on my system hard drive are:
/usr/bin/comskip
/usr/share/doc/comskip
/usr/share/doc/comskip/changelog.Debian.gz
/usr/share/doc/comskip/copyright
/usr/share/man/man1/comskip.1.gz
/var/cache/apt/archives/comskip_0.82.009+git20230112.d0cc422+ds.1-2_amd64.deb

/usr/bin/ionice
/usr/bin/nice
/usr/bin/renice

/usr/share/gtksourceview-4/language-specs/docker.lang
/usr/share/nodejs/prismjs/components/prism-docker.js
/usr/share/nodejs/prismjs/components/prism-docker.min.js

Missing is the shell script  ParallelProcessing.sh   It is also missing in the Debian repository and I could not find it anywhere on the Internet.  I think we need Parallel Processing, but since neither Comskip, nor NextPVR, nor I are installing it, how do we get Comskip running?   

Also attached are my zipped Log files.  Martin, I rebooted my computer this morning to try to reduce the size of the zipped Log files as you suggested, but their size increased to 4.0 MB.

I am using a four port DiSEqC connected to three LNBs (port four is not used).

Port 1: 19.2 Astra 1
Port 2: 28.2 Astra 2
Port 3: 23.5 Astra 3
Port 4: -

When I start Scanning, it seems to be working fine. 
When checking the DiSEqC, I can see that it is using Port 1.
NextPVR finds over 600 channels, which is okay for Astra 1.

Then the channelcounter (Channels found ...) starts over. First the count disappears, then it comes back with a low count.
I suppose NextPVR now wants to scan the transponders on Port 2 (Astra 2) of the DiSEqC, however the port on the DiSEqC has not changed!
The LED on port 1 is still emitting light, so DiSEqC has not switched to Port 2.

After over 30 minutes it is still scanning 12168000 kHz and number of channels is stable at 44. Seems like NextPVR is stalled.

With same hardware, Linux and same dvb-driver and Tuner, I have tested this exact same setup with MythTV and TVheadEnd.
Both work fine controlling the the DiSEqC.
I could just use MythTV or TVheadEnd but I prefer to use NextPVR.

Seems like NextPVR does not send the command to switch the DiSEqC port.

Is this a known issue? Is there a solution for this issue ?
