Я использую эту команду ffmpeg (значения для простоты удалены)
ffmpeg -hwaccel cuvid -c:v h264_cuvid -y -ss 1 -i "FILE0001.MOV" -ss 0 -i "GOPR0621.MP4" -filter_complex

-an -c:v h264_nvenc -preset slow "output.mp4"
на машине с видеокартой cuda.
Я получаю

Stream mapping:
Stream #0:0 (h264_cuvid) -> midequalizer:in0
Stream #1:0 (h264) -> midequalizer:in1
Stream #1:0 (h264) -> lenscorrection
hstack -> Stream #0:0 (h264_nvenc)
Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scaler_0'
Error reinitializing filters!
Та же команда без CUDA работает, т.е.
ffmpeg -y -ss 1 -i "FILE0001.MOV" -ss 0 -i "GOPR0621.MP4" -filter_complex

-an "output.mp4"
Как мне заставить ее работать на машине с Windows 10 с cuda?
