[FFmpeg-user] FFMPEG run out of memory

I am reporting that in some cases where I have a lot of inputs with 
large resolutions the process is killed and sometimes continues for a 
random duration and then just stops with no warning or error.
I was pointing that the RAM seems to be a problem, even that I have 8GB.

  I will try tomorrow a new build and test again.

By the way, I already asked, but this warning is fine ?

It looks a little bit bad.

Thank you!
