I am encoding and decoding the h264 file with nvenc encoders.
When I transcode the file, I also want to resize the the decoded frame with code. I already made ffmpeg build with enable libnpp and with command line i can scale file with scale_npp.
I am Using filtering_video.c ffmpeg sample file.
And instead write
const char *filter_descr = “scale=78:24,transpose=cclock”;
I write const char *filter_descr = “scale_npp=78:24” and run same code but it gives me error–
impossible to convert between the formats supported by the filter scale_npp and the filter
