Topic: VapourSynth SVP doesn't work with DVDs (Windows).

Running Windows 10 x64 with SVP 4 Pro and SMPlayer.

-With MPC and MPCx64, DVD playback with SVP works fine.

-With SMPlayer, normal videos off the hard drive work fine with SVP on or off.

-DVDs in SMPlayer (with SVP's version of mpv as the renderer) work fine when SVP is closed.

-When SVP is open and I'm playing a DVD, I get a black screen with audio, like so:

It's the NTSC Avatar DVD, if that matters. I'm also running a custom refresh rate for the DVD (90hz), but it does the same thing at 60hz, 96hz, and 110hz.

Re: VapourSynth SVP doesn't work with DVDs (Windows).

a part of SVP's log starting from "VideoPlayer: mpv ..." could be helpful wink

I'm afraid it's not very helpful sad

(I heard audio with no video during the 3 minutes it was playing ).

Re: VapourSynth SVP doesn't work with DVDs (Windows).

OK, so I tried ripping the DVD with my usual software (DVDvob2mpg, which should just repackage the video instead of transcoding it).


A. The video is now corrupted for some reason, in both MPC and SMPlayer with SVP off hmm

B. But I get the exact same behavior in SMPlayer. Black screen with SVP on, normal video with SVP closed or the "temporarily disabled" checkbox checked.



Might be something to do with how the video is encoded. It's definitely interlaced, if that matters.

Log from SMPlayer, then MPC:

Any workarounds? Commands to pass to mpv or anything?


I'm desperate now, as MPC (even with EVR/no SVP) suddenly decided it can't play DVDs anymore mad

Re: VapourSynth SVP doesn't work with DVDs (Windows).

Same thing still happens in SMPlayer with the latest SVP update. DVD video is black with SVP turned on, audio works fine.


Also, dragging the whole DVD or the VIDEO_TS folder from the DVD folder to MPV just crashes MPV. However, DVD playback works fine in SMPlayer with SVP turned off.

Re: VapourSynth SVP doesn't work with DVDs (Windows).

It turns out that there're a lot of problems with interlaced videos here... big_smile

1. SVP replaces the entire video filter chain with the vapoursynth filter, while interlaced videos need the yadif filter to be inserted before - luckily this's quite simple to fix

2. SMPlayer sets incorrect mpv option when using "Yadif (normal)" - it sets "--vf-add=yadif" instead of "--vf-add=yadif=frame", so both "Yadif" modes in SMPlayer now output doubled frame rate

3. Vapoursynth filter inside mpv can't properly handle video deinterlaced with doubling frame rate because the video IS actually 50 fps while the internal variable "container_fps" is still set to 25 fps.


So... to make interlaced video work with SVP we need:

1. Fix SVP Manager
2. Force SMPlayer to add "--vf-add=yadif=frame" to advanced mpv options

TY. Added it to the options already, eagerly awaiting a fix smile


I don't suppose the alternative Vapoursynth deinterlacers like EEDI3/NNEDI3 work on the GPU yet, do they? They'd probably kill the CPU during real-time playback.

Maybe nnedi3 OpenCL can be run under VS?

Re: VapourSynth SVP doesn't work with DVDs (Windows).

fixed in 4.0.0.74
