FFmpeg and libav's playbook: Advanced encoding options with hardware-based acceleration, NVIDIA's NVENC and Intel's VAAPI-based encoder.

Hello guys,

Continuing from this guide to building ffmpeg and libav with NVENC and VAAPI enabled, this snippet will cover advanced options that you can use with ffmpeg and libav on both NVENC and VAAPI hardware-based encoders.

For ffmpeg:

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".

Deploying rEFInd on Ubuntu 16.04 LTS with secure boot enabled

Hello guys,

For these dual-booting Ubuntu 16.04 with an alternate operating system in UEFI boot mode, it may often be necessary to use a third-party boot manager such as rEFInd, as it's significantly superior to grub2's on UEFI-capable systems.

This write-up assumes that:

(a). The user is running a current Ubuntu 16.04LTS operating system installation (preferably on a dual-boot system)

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Install Vagrant

sudo su
apt-get update && apt-get install -y libvirt-dev ruby-all-dev apparmor-utils
curl -O -L https://dl.bintray.com/mitchellh/vagrant/vagrant_1.6.5_x86_64.deb
dpkg -i vagrant_1.6.5_x86_64.deb 
aa-complain /usr/lib/libvirt/virt-aa-helper # workaround
exit

Install vagrant-kvm as user
