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:

If you'd like to use a .jar file in your project, but it's not available in any Maven repository, 
you can get around this by creating your own local repository. This is done as follows:

1 - To configure the local repository, add the following section to your pom.xml (inside the <project> tag):
  
  <repositories>
      <repository>
        <id>in-project</id>
        <name>In Project Repo</name>
        <url>file://${project.basedir}/libs</url>

## Instructions to switch odroid over to external ssd
# You shouldn’t see any errors when running this process, if you do. Stop immediately and ask me. 

# run lsblk to see all the hard drives. You should see a line starting with mmcblk0 and then 2 more underneath it with
# mmcblk0p1 and mmcblk0p2. That’s the sd card disk and the sd card partitions. You’ll also see a line starting with
# sda (and/or sdb if there are two usb drives). We want to use the sd* one.  
lsblk 

#pull out some of the values from lsblk so we can automate the rest of the script
read new_partition new_drive mountpoint <<< `lsblk -e 179 -l -o NAME,PKNAME,FSTYPE,MOUNTPOINT |grep 'vfat\s*/media/odroid' | awk {'print $1" "$2" "$4'}`

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".

/**

/* 
   It's pure CSS. 
   Since a quick google search will confirm people going crazy about Mac OS Lion scrollbars...
   this has no fade-out effect.
  
   In Mac OS Lion, the lowest common denominator is always showing scrollbars by a setting.
