Topic: Ubuntu 18.04 - some difficulties

I have just discovered and started using SVP 4 Linux. I have followed the documentation for installation (dependencies, then mpv with vapoursynth from the ppa). I then added the configuration "--input-ipc-server=/tmp/mpvsocket" to mpv.conf file.

When I use SVP, there does not seem to have any errors (after some corrections on my part, using the event log). Videos play normally, but I do not see any difference in any video file. What prompted to think that something is off is the fact that the debugging options don't seem to do anything at all (Demonstration mode and Fluency tests, specifically). There is no "orange bar" and nothing different in the video itself. The Performance page also lists the SVP Index as "N/A".

I have tried with both GPU-accelerated, using Intel UHD 620 integrated graphics. See the attached events log (active.log), the OpenCL log (opencl.log).

Is there something I am missing, or are there other log files that I can go through to see where to look?
Thanks,

Re: Ubuntu 18.04 - some difficulties

If there're no visible errors from SVP's side then you should look into mpv's log.
--log-file=<path>
or just run it from the console

Re: Ubuntu 18.04 - some difficulties

Thanks for the help, I will look into this. I have installed SVP 4 Linux on another PC, this on being a desktop (compared to a laptop) and SVP is working flawlessly!

What I can note now that I have used it on a PC that works, that there is no overlay at all from SVP. It seems as though SVP cannot "capture and write over" the video itself, even though the logs say it is playing the video correctly.

Both debugging options, as noted before, Fluency test and Demonstration mode do not change the video itself either.

Re: Ubuntu 18.04 - some difficulties

Ok, so I executed mpv via command line (I don't know why I have not tried it before) and here is the output:

[autoconvert] can't find video conversion for vaapi/nv12
Disabling filter vapoursynth.00 because it has failed.

From what I have gathered, it seems that the intel-vaapi drivers are in fault. Is there some known error working with intel graphics for use with SVP? Is it possible that some unknown dependency is missing on my system?

Here is the output of vainfo:

Re: Ubuntu 18.04 - some difficulties

--hwdec=auto-copy
or
--hwdec=vdpau-copy
or even
--nwdec=no

Re: Ubuntu 18.04 - some difficulties

Thank you!

The solution was adding --hwdec=auto-copy on the command line or in the mpv.conf file.
