[Libav-user] Filter using Hardware CUDA

[Luis Felipe Domínguez Vega]

Hi, I'm trying to apply some filters using AVFilter, but i getting pixel 
formats problems with this error output:

[2023-01-13 18:46:28.418] [error] FFMPEG internal error: Impossible to 
convert between the formats supported by the filter 'in' and the filter 
'auto_scale_0'

If I comment all the filter code i can decode & encode great using the 
nvidia cuda without CPU ussage. Can you help me to find any bug on my code?

This is the code: https://pastebin.com/VLKrRFCK

Thanks!
