[FFmpeg-user] extract RAW frames into local directory from network camera

[Naveen.B]

Hello,

Thanks for the sharing the useful links,
I tried the way you said, but I am not sure whats happening, I don't see
anything happening after executing the command (neither it saves the jpg
files in the current path), I need to kill the process in later stage and I
get the below error,
