SCXvid filter crash
#1
I tried

core.std.LoadPlugin(path="D:/Programs/Hybrid/64bit/vsfilters/Support/libwwxd64.dll")

core.std.LoadPlugin(path="D:/Programs/Hybrid/64bit/vsfilters/Support/libscxvid.dll")
....
....
clip = core.scxvid.Scxvid(clip)
clip = core.wwxd.WWXD(clip)

the Scxvid dll available in Hybrid crash, while WWXD is not crashing but I don't see any significant improvement.

If they are working on your side, try them on the attached clip and let me know.

Dan

and:
VSPipe.exe -c y4m c:\Users\Selur\Desktop\test.vpy NUL
I get:
Output 1323 frames in 3.90 seconds (338.83 fps)
I get no crash, when using the 'log'-parameter the output file is properly created.

Ah, vsviewer crashes. (no clue why) Hybrid does use libscxvid for chunked encoding where vsViewer isn't used.

Ps.: I split this from the original thread, since it does not seem to be really related.

Scxvid need libxvidcore.dll that probably is installed on your PC.

I searched and libxvidcore.dll is only in the Hybrid/64bit-folder and in no global folder (same for xvidcore.dll), so it is still unclear why it works with vspipe, but crashes with vsViewer. (both residing in the Hybrid/64bit/Vapoursynth-folder)
Renaming libxvidcore.dll to xvidcore.dll and placing it next to libscxvid.dll doesn't change this.
Iirc. xvidcore.dll is only needed to compile the filter.

In effect it seems that the "dll" has not dependencies on xvid.
But on my side it is crashing both with vsViewer than vspipe.
It could be a problem related to the version of Vapoursynth.

If is working on your side try it with the clip that I attached in my previous post.

Any scene change detection function that I tried fail to find any scene change with this clip.

So before spend ti time to get SCXvid working on my side, I'd like to know if this function is good enough to handle this clip.

Thanks,
Dan
