How can we take decklink input from QUAD 2 capture card  and use the gpu
for transcoding at same time , could anyone provide the example or tutorial
steps for it , as i have compile ffmpeg with gpu and decklink , but i could
not use hardware acceleration with decklink input

*ffmpeg -fflags +genpts -vsync 0 -fflags +genpts -vsync 0 -hwaccel_device 1
-hwaccel nvdec -hwaccel_output_format cuda -format_code Hi50 -f decklink -i
'DeckLink Quad (1)'  -vf "format=yuv420p,yadif=0:-1:0,scale=1920:1080"
 -b:v 3.5M -bf 1 -aspect 16:9 -profile:v main -preset:v medium -c:v
h264_nvenc -c:a aac -b:a 128k -ar 48000 -strict -2 -f flv
