why ffmpeg is not working in new installation - ffmpeg

Question

I was working on live encoding from FFmpeg from last few days. One day I re-installed my OS and tried to run FFmpeg commands again after configuration. My publish points get in starting but could not started. Why? Am I missing any configuration required?
The command I am trying to run is:
ffmpeg -y -re -i D:\video2.mp4 -pix_fmt yuv420p -movflags isml+frag_keyframe -f ismv -threads 0 -c:v libx264 -preset fast -profile:v baseline -map 0:v -b:v:0 800k http://localhost/PPS/PublishPoint.isml/Streams(Encode
r1)
Output what I got in command prompt is:

Answer 1

I changed my devices as I was using HD Webcam replaced with simple devices and It worked fine.
So, I found one solution of this problem but can't say it is ideal.
Thanks.
