Help Please

[joolsc]

I have installed NextPVR 5.2.2.211017  on my Synology box and can access the GUI to set up my HDHomerun with channel info. After that I've run into problems. First I can't get any guide data to download using the DVB EPG. Then when I try and playback any channel, some work (but take many seconds to connect) whilst others comeback with "Browser blocked video playback" this happens sometimes but not always and when video does play it stutters due to buffering.
I have also installed the app on my Nvidia Shield and when the app starts it shows a server at an address I don't recogize beginning 172.xxx.x.xxx.? I cant access this and cant access the server on Synology. All devices are on my home network and I'm trying to access the PVR server over LAN
Im not familiar with docker but think I've set it up OK but would appreciate some help with suggestions for the problems I'm seeing.Logs attached

OK I can understand the frustration there is a lot going on here

1. I don't think DVB EPG is available on Silicon Dust devices, sub will need to confirm.

2. The blocker browsing NextPVR is no different then the browser blocking internet sites so make sure your browser is set up properly.

3. Your server is not fast enough to do s/w transcoding which is why they stutter

2021-11-12 11:48:08.687 [DEBUG][37] [FFMPEG]: frame= 365 fps= 22 q=21.0 size=N/A time=00:00:16.08 bitrate=N/A speed=0.976x

You will need to investigate if VAAPI passthrough in Docker.

4. For discover to work in addition to 16891 UDP being opened you have to set the HOST_IP= environment variable to the IP of the Docker host.

I'm assuming you're using firefox? If so, you'd need to unblock video playback

but not always and when video does play it stutters due to buffering.

Unfortunately NAS devices can be a bit marginal CPU-wise for playback in the browser, since it needs to be able to transcode in real time to a video format compatible with browser. However, you'll be find streaming to clients like nlite or kodi etc that can play the native streams.

As Martin indicated, depending on the NAS you're on, you might be able to get web playback working by using hardware accelerated encoding. ie, maybe delete and recreate your docker image using the command line (after which you can stop/start it etc from the Docker application):

Code:

sudo docker run -d --name nextpvr --volume /volume1/temp/config:/config --volume /volume1/temp/recordings:/recordings --volume /volume1/temp/recordings:/buffer --publish 8866:8866 --device /dev/dri:/dev/dri nextpvr/nextpvr_amd64:stable

On the Settings->Transcoder page, you can then set the Video Encoder to VAAPI

Just as an FYI, on Synology if you want to do the hardware acceleration you have to do it from the command line. The Synology GUI (at least the 6.x version) has no option to add the needed options. I never bothered trying that as I never watch stuff from the browser, and I really didn't want to try and figure out the command line Docker stuff on the Synology.

This combination is supposed work. It does need the HOST_IP environment variable set with the address of the host.

Thanks I didn't know you could mix HDHR mode with EPG via rtp.

Yeah, HDHR devices fall back to legacy style rtp when they need the EPG. It's the only way to get the specific streams NextPVR needs from the HDHR

Thanks very much for all the replies. What I'm after is really to use the install on the Synology purely to record TV . I'm not wanting to watch from a browser but only to record TV then I'll use MCEBuddy to remove adds and move the file to Plex folder to watch on TV.
Re: the above quoted , being a complete novice with Docker can you describe how I go about setting the HOST_IP environment variable? When I set this up with Docker on the Synology I didnt see any way to enter this sort of info. I just went through the Docker GUI steps.
I'm starting to think this isn't set up correctly at all. I tried using Schedules Direct to populate the the Guide data but nothing happens. I tried to download Channel icons, nothing happens. I have the Android app and it can't connect and comes up with a server IP which I now know is an internal Docker IP? I see from the install notes for NextPVr on Docker it give the following install insructions:
docker run -d \

    --name nextpvr \
    --volume /home/graeme/config:/config \                     
    --volume /home/graeme/videos:/recordings \
    --volume /home/graeme/videos:/buffer \
    --restart unless-stopped \
    --publish 8866:8866 \
    --publish 16891:16891/udp \
    nextpvr/nextpvr_amd64table

If you're using an older legacy HDHomeRun, you'll also need a couple more parameters (replacing 192.168.1.51 with your host's IP address):
    --env HOST_IP=192.168.1.51 \
    --publish 8026:8026/udp \

On Synology I dont see how I enter this information the Docker app is just a GUI ?
Any help with exactly how to enter the above data would maybe solve some of the issues I'm getting. I've searched for days to find some info on the net but can't find any clear instructions, but then maybe it is installed OK, I just dont know.

The Synology Docker GUI app doesn’t provide the ability to set everything. You can however enable ssh support, then ssh into the NAS, and just run the docker command line with whatever parameters you want (like my example further up the page). After this you it’ll just show up in the Docker GUI app and you can start/stop it from there etc.

Do you have a Schedules Direct account and wanting to use that? On the Settings->Guide page, enter you Schedules Direct login, and an SD lineup, then on Settings -> Channels, click advanced tools -> auto map to map the guide data to your device.
