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.

Sometimes when working with Git you'd like to commit binary files.
But those files won't have clean comparisons with Git standard diff command.
Fortunately Git is a great tool that comes with a lot of possibilities…

MS Office

If, as a developer, you are under company constraints and must use MS Office,
you'll encounter some issues when trying to diff MS Office files.

Maybe you're asking yourself: what's the problem with that?
