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.

So you love the Operator Mono font? I don't blame you! So do we! It's a bit pricey but worth every penny.

In fact, we're so used to it in our editors that we were a bit sad with GitHub's otherwise neat code views. When we review PRs in the web UI, we want our Operator Mono!

So, assuming you have it installed on your machine, you can put the JS bit in the other code snippet of this Gist in a bookmarklet, and click it when you're on a GitHub.com page you want to have switch over to our beloved font. We used the ScreenSmart variant here, which you get in the font package and have probably installed, as it's the more legible one on screens. Feel free to adjust the font name if needed.

Hi! Thank you for offering a PR for one of my open source libraries. I really
appreciate it, because in most cases, I have very little time to maintain them.

I often get PRs that lead to a back-and-forth between me and the contributor,
where I ask them to undo many of the changes they have made. To avoid this in
your case, or to at least give you an idea why I'm asking you to adapt your PR,
here are my criteria for accepting PRs.

Every PR should have one, and only one, unique goal. Your PR should make the
absolute minimum number of changes that are required to achieve this goal.
