[FFmpeg-user] How to perform two filters: overlay an image and apply .acv color curve?

[Michael Shaffer]

I got it working,

c:\ffmpeg\bin\ffmpeg1.exe -f image2 -loop 1 -i
C:\Users\USER500\Downloads\Aexport.png -re -rtsp_transport tcp -i "rtsp://
admin:admin at 192.168.1.101:554/VideoInput/1/h264/1" -filter_complex
"[0:v]format=argb,geq=r='r(X,Y)':a='0.7*alpha(X,Y)'[ov1];
[1:v]curves=psfile=vvvlight.acv[ov2];
[ov2][ov1]overlay=5:main_h-overlay_h" -f lavfi -f dshow -rtbufsize 2000M
-thread_queue_size 5096 -i audio="virtual-audio-capturer" -c:a libmp3lame
-ab 128k -ar 44100 -c:v libx264 -preset fast -crf 30 -x264-params
keyint=60:scenecut=0 -threads 0 -bufsize 512k -f flv "rtmp://
