mea culpa, j'essaie ça de suite
Edit: Il ignore l'option mais la qualité est meilleur.
L'utilisation GPU est basse (bcp plus basse que mon encodeur Vidéo séparé).
Je laisse tomber.
ffmpeg.exe -y -hwaccel cuvid -c:v h264_cuvid -vsync 0 -i C:\Fraps\Movies\short_movie.avi -vcodec h264_nvenc -crf 22 C:\Fraps\Movies\short_movie_gpu.avi
Codec AVOption crf (Select the quality for constant quality mode) specified for output file #0 (C:\Fraps\Movies\short_movie_gpu.avi) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Output #0, avi, to 'C:\Fraps\Movies\short_movie_gpu.avi':
