>> Please find attached a CUDA based scale filter. This filter will be a starting point to add other CUDA based filters. The filter supports 420-8, 420-10, 444-8, 444-10 formats and will help to do complete 10-bit HW accelerated transcoding when using >> CUVID.
>> Currently the filter requires a manual step of generating the PTX files. The commands for generating the PTX files have been put in build.bat inside the CUDA folder that has been created as a subfolder within libavfilter.
>> There is an existing scale_npp filter however that filter supports only 8 bit and has lower performance than the current one.

Are there any plans to include this in the repo. Anything that I can support here to make it worthy. 

Thanks,
Yogender
