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.

# There's a lack of sample code for acme/Let's Encrypt out there, and
# this is an attempt to at least slightly remedy that.  It's the result
# of my first day's hacking on this stuff, so almost certainly contains
# errors and oversights.

# It's not designed to be specifically useful if what you want is 
# just a cert -- certbot or dehydrated are better for that.  It is sample
# code for people who are building automated systems to deal with large
