GPU Acceleration

You can override the string in the <TranscodeHLS> setting of config.xml.

Look at the "Using transcoder args" log message in nrecord.log to give you the starting point for replacing 'default' with.

Thanks Sub, 


I have added it here:


<TranscodeHLS>default</TranscodeHLS>
    <VideoEncoder>D3D11VA</VideoEncoder>
    <TranscodeArgsHLS>-y [SEEK] -i [SOURCE] -map_metadata -1 -threads 0 -map 0:0 -map 0:1 -map -0 -codec:v:0 libx264 -pix_fmt yuv420p -preset superfast -crf 23 -b:v [BITRATE] -maxrate [BITRATE] -bufsize 2698344 -vsync vfr -profile:v high -level 41 -aspect [ASPECT] -force_key_frames \"expr:gte(t,n_forced*3)\" -s [RESOLUTION] [SUBTITLES] -flags -global_header -sc_threshold 0 -codec:a:0 aac -strict experimental -ac 2 -ab 128000 -af \"adelay=1,aresample=async=1\" -hls_time 3 -start_number 0 -hls_list_size 0 -init_hw_device qsv=hw -filter_hw_device hw -vf hwupload=extra_hw_frames=64,format=qsv -y [TARGET]</TranscodeArgsHLS>

But it does not pick it up:

Have I put it in the wrong place?

I think I finally made it work...I had to setup a profile as well....not leave it to default.

And it does work with the service as well...

[aderlopas]

In the end I thought I'd give it another try...
So I removed again the additional switches from config.xml and tried again...
And now it works with the original switches! Stranger Things....
Of course from the time I had tested this in the beginning, I installed latest Intel MSDN SDK and LAVfilters...don't know if that played any role...

To help me catch up ... Is GPU encoding working when Settings -> Transcoder -> Video Encoder is set to Intel and NextPVR Server is running as a Windows Service?

Yes it does...eventually although I have left it to D3D11VA because it uses much more GPU (and much less CPU) that if I use INTEL.

Thanks ... I shall investigate tomorrow.

Weird. If you put it back to "default", does it now work?

Surprisingly, yes it now works. Of course  I also reinstalled the latest version of NextPVR again in order to revert the older DLL I copied previously.

Has anyone got Nvidia GPU acceleration working within a docker / pass through. I have just got NextPVR working on Unraid in a docker. At the moment the only options I have within the transcoder Video Encoder section are CPU & VAAPI

[mvallevand]

That probably should have been posted in the Docker sub forum not Windows. You can write custom scripts if you know what you are doing but I suggest using direct play clients and avoid the trouble.
