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:

Streaming your Linux desktop to Youtube and Twitch via Nvidia's NVENC and VAAPI:

Considerations to take when live streaming:

The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:

1. Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.

2. Set up the encoders as shown:

Building Tensorflow from source on Ubuntu 16.04LTS for maximum performance:

TensorFlow is now distributed under an Apache v2 open source license on GitHub.

On Ubuntu 16.04LTS+:

Step 1. Install NVIDIA CUDA:

To use TensorFlow with NVIDIA GPUs, the first step is to install the CUDA Toolkit as shown:

How to install NVIDIA Docker 2 package on Ubuntu and Debian:

If you came to this result (from Google or elsewhere) after realizing that Nvidia-docker's entry on this subject does not result in a working installation, here are the basic steps needed to install this package correctly:

For starters, ensure that you've installed the latest Docker Community edition by following the steps below:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

This script utilizes ffmpeg, the same tool Plex uses, to decode the video stream and captures the output for any errors during playback and sends the playback errors to a log file. So essentially it plays the video in the background faster than regular speed. It then checks the error output log file to see if there is anything inside. If ffmpeg was able to cleanly play the file, it counts as a passed file. If there is any error output, an error could be anything from a container issue, a missed frame issue, media corruption or more, it counts the file as failed. So if there would be an issue with playback and a video freezing, it would be caught by this method of checking for errors. Because of the nature of the error log, any errors that show up, even simple ones, will all count as a fail and the output is captured so you can view the error log. Some simple errors are easy to fix so I have included an auto-repair feature which attempts to re-encode the file which is able to correct some issues that would cau

I was able to find a VERY QUICK AND DIRTY way to use the media-autobuild suite to compile my own 64-bit static FFmpeg for Windows with the NDI library.

Download it and extract to a place on your computer, and keep note of the path. I put it in "D:\ndi\media-autobuild_suite-master", so for the sake of these instructions when you see "<autobuild>", you need to substitute whatever path you've put it in.

During the initial setup process, request to use the static build and add whatever else you'd like to have in your ffmpeg, then pause what you're doing when the on-screen prompts tell you the ffmpeg_options file has been written, then go into <autobuild>\build\ffmpeg_options.txt and add somewhere a line with
