Using dshow or ffmpeg as an input to NPVR?

[mvallevand]

What I meant is there are cheap HDMI encoders that you could probably buy with the money that you get selling such a sophisticated card that does all the work for you.

Assuming you have a command line you like, it can be adjusted easily enough just by changing the batch file

In C:\Users\Public\NPVR-data create a file extras-ProCapture.xml with this content

Code:

<channel name={"channel-name"}>
    <command>cmd</command>
    <args>/c C:\Users\Public\NPVR-data\scripts\ProCapture.bat {channel}</args>
</channel>

In C:\Users\Public\NPVR-data\scripts create a file ProCapture.bat with this content

Code:

rem insert blasting code here
"C:\Program Files\NPVR\Other\ffmpeg" -f dshow -i video="Video (00 Pro Capture HDMI 4K+)":audio="Audio (00 Pro Capture HDMI 4K+)" -vcodec h264  -acodec aac  -s 1920x1080 -framerate 50 -f mpegts -

In NextPVR go to setting device, find the Extras device, rescan if necessary. choose your source Schedules Direct or XMLTV file and then disable the stations your don't want.

Hi...sorry for the slow reply. Here are my exact steps taken:

Have created an extras XML file as so (I don't have 'NPVR-data/scripts', I have 'NPV/Scripts' instead):

<channel name="channel-name">
<command>cmd</command>
<args>/c C:\Users\Public\NPVR\Scripts\ProCapture.bat {channel}</args>
</channel>

Then as I am using VLC and this is on a different drive to your example one, I have used the following in my batch file (rem line removed for now altogether):

"G:\VLC" vlc --ffmpeg-hw --avcodec-hw=any dshow:// :dshow-vdev="Video (00 Pro Capture HDMI 4K+)" :dshow-adev="Audio (2- 00 Pro Capture HDMI 4K+)" :dshow-threads=8 :dshow-aspect-ratio=16\:9 :dshow-size="3840x2160" :dshow-pixel_format=cuda :dshow-tune=film :dshow-preset=lossless :dshow-profile=main10 show-vcodec=hevc_nvenc :dshow-chroma=RV32 :dshow-fps=50 :dshow-crf=0 :dshow-acodec=mp4a :dshow-stereo-mode=5 :dshow-force-surround-sound=0 :dshow-ab=128 :dshow-samplerate=44100 :no-dshow-config :live-caching=100

However, I get no extra device appearing in NPVR, even after relaunching the program. Do I have to reference the blaster code to get this to work, or have I done something else wrong?

Thanks

You have done lots of things wrong some of it could be forum formatting.

- you changed the NextPVR V5 data folder for no valid reason, you actually have to do extra work to do that.
- you may not even have a working v5 setup
- not sure if your really meant NPV/scripts or not
- the xml file needs to be in the data folder
- you are using VLC so you are on your own, but you will need something like dst=std{access=file,mux=ts,dst=-} on your command line that is as far as I go

...sorry, I was still using v4. Let me try again now and come back to you...

Ok, I now have NPVR v5 set up. It is now recognising the extra device, but not finding any channels when I scan for them. I have reverted back to ffmpeg temporarily and now have the following:

The .xml file:

Code:

<channel name="Test1">
    <command>cmd</command>
    <args>/c C:\Users\Public\NPVR-data\scripts\ProCapture.bat {channel}</args>
</channel>

The .bat file:

Code:

"G:\NPVR\Other\ffmpeg" -f dshow -i video="Video (00 Pro Capture HDMI 4K+)":audio="Audio (00 Pro Capture HDMI 4K+)" -vcodec h264  -acodec aac  -s 1920x1080 -framerate 50 -f mpegts -

Once I have a working picture on a single channel I will look at switching to VLC, but for now I am stuck on the channel mapping in the server. Any ideas?

Thanks

You need to have Schedules Direct or an XMLTV file with your station list as input for the scan and leave the name="channel-name" like I posted

Ok, I'll look at doing this bit tomorrow. Thanks.

Ok probably best to delete that bad Extras entry in Settings->Devices and reimport it with the correct format. Hold the Control key and you get a delete option.

Ok, am back. Where do I put my XMLTV file so that NPVR can detect it?

...I don't have an import button for my extras device btw...only scan and that returns nothing...
