we have multicast that has multiple video bitrates and audios in it. We are
trying to copy out some snapshot of the stream using -copy. It is 10
minutes and according to benchmark parameter, the maximum amount of memory
uses 1.6GB which is a lot, considering that it should just read the
multicast and save it into output file. Please check this pastebing  -
https://pastebin.com/rVXhKivd. It shows the ffmpeg command at the beginning
and the the bottom, there is memory used.

Is there a way to lower the amount of RAM used?

Thank you
