Description (last modified by Carl Eugen Hoyos)

The following commit breaks the CUDA build using the MSVC compiler:
cfdddec0c832a67da8a0081a32ae2c7127ce2368

Using MSVC 2015 generates the following error:
libavfilter/vf_scale_cuda_bicubic.ptx.c(1925): fatal error C1091: compiler limit: string exceeds 65535 bytes in length

Using MSVC 2019 the following error is generated:
libavfilter/vf_scale_cuda_bicubic.ptx.c(2818): fatal error C1060: compiler is out of heap space

It looks like an alternate method for converting the ptx contents to const char [] needs to be implemented such that a string literal is not used like a const char [] assigned an array of integers.
