Topic: Pin info: wrong or bug?

Hi!

This is my video chain: LAV Filters -> SVP -> madVR on Windows 10 x64 with an AMD RX 480

LAV Video Decoder deinterlace at 25/30 fps, so SVP works even with interlaced material (i.e. from PAL DVDs and Video BD).

SVP seems to work perfectly, and the OSD shows "played at 50.000 or 59.940 fps" rispectly for 25.000 or 23.976 and 29.970 fps, but from the FFDShow OUT pin info I see that SD material (720x576 or less) goes out to madVR at 1024x576, and HD material goes out at 2048x1080 both with the same input fps. madVR In pin info corfirme that.

To be clear: pin infos doesn't shows the converted frame rate, but an increased orizontal resolution that goes on multiplier of 1024: if this would be true, FFDShow does an unwated resize of the image and madVR does another resize to the screen resolution, that is very bad when source material and display has the same resolution (i.e. BD and screen at 1920x1080).

Doesn't have FFDShow OUT pin info to show same resolution of input with increased frame rate (i.e. 720x575@50.000 for PAL DVDs and 1920x1080@59.970 fps for BDs)?

I think this's just a madVR's feature, you can ignore it.
What matters is movie size displayed in madVR's on-screen stats.

1024x576 is standard resolution for decoded picture from PAL DVD 16:9 with anamorphic flag.
Check it maybe it is your case.

no it isn't

I don't think it's the case, because it happens always, no matter if the source is a film from a PAL DVD, a file, a video, and so on.

@Chainik

The data on madVR OSD confirmes what the data on SVP OSD says about the frame rate (i.e. a 23.976fps or 29.970fps file played at 59.940 and a 25.000fps file played at 50.000fps), and the resolution of the input file scaled at the display resolution, so I assumed that everything works fine.

The dubs came out when doing the setting of my system (i.e deciding where to do deinterlacing - LAV or madVR, if in film or video mode, etc.): I used the pin infos, and I started to wonder why the FFDShow OUT pin info always showed the orizontal resolution in multiplier of 1024 and never the incremented frame rate...

And it really drived me crazy trying to understand where and what caused the resize: it seemed like that the script used in Avisynth changed both frame rate and resolution, but I wasn't able to find it, neither in the FFDShow settings!!!
