[SOLVED] Utlizing NVIDIA DECODER inside the FFMpeg custom encode node

[veks]

Hi all!
I'm trying to figure out how to utilize NVDEC inside the FFMpeg custom node.
I've tried, and I always get this error:


The command I'm using inside the FFMpeg custom node is:

-pix_fmt yuv420p -vf "scale=960:540,yadif=1" -vsync 1 -hwaccel cuvid -hwaccel_device 1 -hwaccel cuda -hwaccel_output_format cuda -vcodec h264_nvenc -r 25 -g 25 -b:v 1700k -bufsize 1216k -maxrate 1800k -preset medium -profile:v main -acodec aac -b:a 64k -ac 2 -ar 48000 -af "aresample=async=1:min_hard_comp=0.100000:first_pts=0"

Thanks!

Hi Vedran,

The "hwaccel" options are input options and cannot be used as output options. However, when using the custom ffmpeg encoder you cannot currently specify any input options so your only option is to use command executor:

%comspec% /C ""%s_ffmpegx64%" -hwaccel cuvid -hwaccel_device 1 -hwaccel cuda -hwaccel_output_format cuda -i "%s_source%" -pix_fmt yuv420p -vf "scale=960:540,yadif=1" -vsync 1 -vcodec h264_nvenc -r 25 -g 25 -b:v 1700k -bufsize 1216k -maxrate 1800k -preset medium -profile:v main -acodec aac -b:a 64k -ac 2 -ar 48000 -af "aresample=async=1:min_hard_comp=0.100000:first_pts=0" -y "x:\some path\file.mp4""

And of course it's good practice to make sure your command works in normal dos before trying to implement it in ffastrans

Hi,
I've tried using the command node with this command, any idea what's wrong?

Hey veks,

not that i ever used cuda functionality but i suppose using "hwupload_cuda" might be the solution?

Hi,
now I'm trying with this ffmpeg command, but file always goes to root C:\ and filename is the whole UNC path.

Am I'm missing some " or ' ?

Thanks!

EDIT: Added ' on beggining and on the end of each UNC path, and now it works.
