See https://en.bitcoin.it/wiki/BIP_0070 for the latest version of this document; I'll keep this document so the process of discussion/revision isn't lost.
This document proposes protocol buffer-based formats for a simple payment protocol between a customer's bitcoin client software and a merchant.
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…
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?
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.
