Fenced code blocks inside ordered and unordered lists

1. This is a numbered list.

2. I'm going to include a fenced code block as part of this bullet:

Useful Examples of ffmpeg and GNU parallel on the command-line:

Transcoding FLAC music to Opus:

ffmpeg is a highly useful application for converting music and videos. However, audio transcoding is limited to a a single core. If you have a large FLAC archive and you wanted to compress it into the efficient Opus codec, it would take forever with the fastest processor to complete, unless you were to take advantage of all cores in your CPU.

parallel 'ffmpeg -v 0 -i "{}" -c:a libopus -b:a 128k "{.}.opus"' ::: $(find -type f -name '*.flac')

Transcoding Videos to VP9:

Installing PDFtk Server edittion on your Mac

This workaround install is necessary because PDFtk was pulled from homebrew-cask due to issues with it aggressively overwriting file permissions that could impact other installed libraries. See this homebrew-cask issue.

The following steps worked on Mac OS X 10.10.1 with a standard brew installation for the PDFtk Mac OS X server libary version 2.02.

All Terminal commands separated by a full line space. Some commands wrap into multiple lines.

Download and extract the Mac OS X server install pacakge

Creating Timelapse Video From Photos With FFMPEG

Man, there are a lot of outdated and incomplete tutorials about creating timelapse videos from JPG images and photos. Here's a quick start guide to get going in late 2019.

Software

I'm using ffmpeg version 4.2.1 on MacOS. It is free, well supported, and scales up to practically any number of input images or output video length.

There are a dozen paid timelapse software offerings out there, but I suspect they are just polished front-ends to ffmpeg. Small timelapse videos are possible in iMovie 10.1, but adding even a modest number of images bogs it down badly. The easiest approach is to create a rough lightly compressed video with ffmpeg and then edit the result in iMovie.
