Dear my friend, We replace cpu with gpu to ffmpeg recently, I set the gpu device no, but it still use default device 0. As the following problem Code: ffmpeg -hwaccel_device 2 -hwaccel cuvid -i a.mp4 -vf “scale=1080:720,overlay=()” -c:v h264_nvenc out.mp4
I found if use “scale_npp” replace “scale” will work with device 2, but in that way, we will lost some filter functions like overlay,suntitles burning,and so on.Is there some parameters of scale_npp with the same functions? Or how can I implement add water picture on gpu platform with seted device number? Linux server has 5 NVIDIA card, i see it use device 0 always by the nvidia-smi tool. Hope your help, thank you! _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
