SCXvid filter crash - Dan64 - 09.07.2024
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.

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.
RE: SCXvid filter crash - Dan64 - 09.07.2024
Scxvid need libxvidcore.dll that probably is installed on your PC.
RE: SCXvid filter crash - Selur - 10.07.2024
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.
RE: SCXvid filter crash - Dan64 - 10.07.2024
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
RE: SCXvid filter crash - Selur - 10.07.2024
I'll do some testing after work an report back.
RE: SCXvid filter crash - Selur - 12.07.2024
Hmm,.. SCXvid, does create a log file, but from the looks of it, it does not set '_SceneChangeNext'
So better stick with misc.SCDetect, mv.SCDetection and wwxd.WWXD (this one uses different props).
(core.misc.SCDetect is probably the one I would choose)

RE: SCXvid filter crash - Dan64 - 12.07.2024
I have the same opinion.
The problems with scene change detection usually are due when in the clip are used the transitions to change from one scene to another.
In this case, since usually the algorithm for scene change detection compares the previous frame with the current, fails to detect the scene change.
I will develop an extended version of SCDetect where it will be possible to specify the frame lag for the comparison (*) , in this way the transitions should be detected.

(*) in case of lag=1 it will be used directly misc.SCDetect
