why ffmpeg is not working in new installation -


i working on live encoding ffmpeg last few days. 1 day re-installed os , tried run ffmpeg commands again after configuration. publish points in starting not started. why? missing configuration required?

the command trying 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 got in command prompt is:
