#   
#   This script is intended to start on launch and run on an always connected device on a network (eg: server).
#   It scans the network with 'arp -a' and sends a notification webhook whenever recognizes a new mac address on the network.
#
#   For auto-run on login you can rename the script to a .command and add it to your Login items on Mac OS or
#   modify the script to remove the loop and take a look at crontab

Converting mkv to mp4 with ffmpeg

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.
