I'm getting some problems loading a transparent PNG (a logo) and add it on a video using overlay.
The alpha from the PNG seems to be read just fine, but it's the "24bit" of the full 32bit PNG itself that are read with lots of artefacts (mainly "blocks" not available in the original image).
ImageSource and ImageReader both gives the same output.
With regular AVS 2.6 the same PNG/overlay works as expected.

Syntax:
logo=imagesource("logo.png",pixel_type="rgb32")
overlay(video,logo,mask=logo.showalpha())

Of course, for most input formats they are just aliases of one single function. A difference might exist if you change the decoder, e.g. using DevIL or not.

Do you have samples of such wrong results (original image + wrong overlay result in a script)? I wonder where such issues appear, I could imagine in areas which should be completely transparent: Here the alpha channel may hide the fact that there are areas of full transparent color A next to full transparent color B, which would appear visibly if the transparency is incomplete by mistake. But then it may be rather in Overlay than in ImageSource.

Just a wild guess: Alpha channels are usual rather in RGB formats and should not have coring applied, even when the overlay result is in YUV format.

Tried it with a sample png from here and I can see no garbage.
Which Avisynth Plus version are you using?

I don't expect speed gain, unless the heavily used filters are optimized further. Maybe you can omit some YUY2<->YV16 conversions.

I'm using r2294.
Original image:
https://www.sendspace.com/file/ad7xdd

This is the alpha (correct):
http://116.imagebam.com/download/hau...2355/Alpha.png

This is the image without alpha (wrong):
http://115.imagebam.com/download/QWD...2359/Image.png

Final result with overlay (wrong):
http://116.imagebam.com/download/4mo...66/Overlay.png

Setting pc_range=true, indeed, fixed the output in the right way, thanks!

Just asking: Is it right that when opening the png (either 32bit or forcing 24bit) with imagesource (without applying any overlay), the image is still blocky like in my previous example?

png must be multiplied by alpha, this is normal

Yes, this png have only 0 and 255 values in rgb, the greyshades are only in the mask , alpha channel.

AVSMeter does not use the C interface.

fadein/fadeout don't work:
"BlankClip: color count 13 does not match to component count 3"

Yes, I've come across that as well when trying to use LSFmod.

Suggestion to CombinePlanes: if source clip only has a Y plane and "source_planes" is not set, use the Y plane.
Also, if "planes" is set, why do we need "pixel_type"? Can't "pixel_type" be figured out automatically, or am I missing some case when it can't?

Changes since r2294: see above. Last change:

20161206 r2331dev
  • YUY2 PlaneToY
  • C interface compatible array-type AVSValue handling (avspmod issue)
I updated to the latest r3333 build. Avspmod is still not working.

These are not fatal errors.
I have just tried 64 bit avspmod and it was producing me an exception and exited before start and was able to debug avisynth. After one more modification it works for me, those error-like warnings are still there of course.
