For me, this is a little weird to resize Y with dnn backend but resize
UV channel with FFmpeg swscale, is it used the same scale algorithm ?

are resized with swscale.
The command to use espcn.pb (see vf_sr) looks like:
./ffmpeg -i 480p.jpg -vf
format=yuv420p,dnn_processing=dnn_backend=tensorflow:model=espcn.pb:input=x:output=y
-y tmp.espcn.jpg
