How to Sign and Release to The Central Repository with GitHub Actions

GitHub allows automated builds using GitHub Actions. A commonly asked question is how to release artifacts (packaged Java jars) built by Maven and Gradle to The Central Repository. The GitHub Actions documentation provides only part of the answer.

So, first, configure your Maven project for staging artifacts to The Central Repository, by reading through Configuring Your Project for Deployment and following those steps. Please make sure that the maven-gpg-plugin is configured to prevent gpg from using PIN entry programs, as follows:

<configuration>
  <gpgArguments>
      <arg>--pinentry-mode</arg>
 loopback

Minimalist static FFmpeg build on Ubuntu 18.10 with Nvidia NVENC enabled.

Original guide with a standard build is here.

With this guide, I'm adding more instructions to enable support for NVIDIA CUVID and NVIDIA NPP for enhanced encode and decode performance.

First, prepare for the build and create the work space directory:

cd ~/

Spawning multiple ffmpeg processes with xargs:

On standard NVIDIA GPUs (Not the Quadros and Tesla lines), NVENC encodes are limited to two simultaneous sessions. The sample below illustrates how to pass a list of AVI files to ffmpeg and encode them to HEVC on two encode sessions:

$ find Videos/ -type f -name \*.avi -print | sed 's/.avi$//' |\
  xargs -n 1 -I@ -P 2 ffmpeg -i "@.avi" -c:a aac -c:v hevc_nvenc "@.mp4"

This will find all files with the ending .avi in the directory Videos/ and transcode them into HEVC/H265+AAC files with the ending .mp4. The noteworthy part here is the -P 2 to xargs, which starts up to two processes in parallel.
