d2vsource 1.0 is the one with the bug. There is no release with the fix yet. However, you don't need to compile d2vsource. There is a simple workaround:

Not quite. If you have a 9..15 bit clip, filters can produce pixels with values greater than the bit depth's maximum, up to 65535. I think this can be considered a bug, though, i.e. someone else's...

You can have float pixels with values outside the "legal" ranges in VapourSynth. However, I'm not sure the resizer is supposed to create such pixels in this case.

The difference between the black...

Now you know why this set of GNUmakefile and configure sucks. :) Even though lots of people adopted them. It does strip the library. It may work better if you add this under line 110 in configure:

Make your filter accept (only?) integer clips and give it the video straight from d2vsource, without the conversion to RGBS. Then you can directly use the pointers returned by getReadPtr (they are...

Maybe -O2 instead of -O3, but I doubt that helps.

You can debug it in Linux too. You need to add -ggdb3 to CXXFLAGS and make sure the library doesn't get stripped. Then you can invoke gdb:

1. Try to remove -ffast-math from configure. It enables potentially unsafe optimisations for floating point math.

Is d.filename initialised with zeroes? If not, strcat may find a zero past its end. Use the "n" versions of string functions if possible, i.e. strncat. Although I don't see why this isn't str(n)cpy....

get_read_array is a Python function. Aren't you doing this in C(++)? But yeah, if you want to do it in Python you'll want to use get_read_array and get_write_array to access the pixels.
