FFmpeg

FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. under a wide variety of build environments, machine architectures, and configurations.

It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications. As well as ffmpeg, ffplay and ffprobe which can be used by end users for transcoding and playing.

The FFmpeg project tries to provide the best technically possible solution for developers of applications and end users alike. To achieve this we combine the best free software options available. We slightly favor our own code to keep the dependencies on other libs low and to maximize code sharing between parts of FFmpeg. Wherever the question of “best” cannot be answered we support both options so the end user can choose.

Everyone is welcome in FFmpeg and all contributions are welcome too. We are happy to receive patches, pull requests, bug reports, donations or any other type of contribution.

Security is a high priority and code review is always done with security in mind. Though due to the very large amounts of code touching untrusted data security issues are unavoidable and thus we provide as quick as possible updates to our last stable releases when new security issues are found.

Certbot automatically enable HTTPS on your website

certbot is an easy-to-use automatic client that fetches and deploys SSL/TLS certificates for your webserver. Certbot was developed by EFF and others as a client for Let’s Encrypt and was previously known as “the official Let’s Encrypt client” or “the Let’s Encrypt Python client.” Certbot will also work with any other CAs that support the ACME protocol.

While there are many other clients that implement the ACME protocol to fetch certificates, Certbot is the most extensive client and can automatically configure your webserver to start serving over HTTPS immediately. For Apache, it can also optionally automate security tasks such as tuning ciphersuites and enabling important security features such as HTTP → HTTPS redirects, OCSP stapling, HSTS, and upgrade-insecure-requests.

Certbot is part of EFF’s larger effort to encrypt the entire Internet. Websites need to use HTTPS to secure the web. Along with HTTPS Everywhere, Certbot aims to build a network that is more structurally private, safe, and protected against censorship.
