How to view a video on Parler

Let's say you have a video ID, like wfy02V209EwU taken from this map

The link for the video kiBnNejo0JW0 is at https://video.parler.com/ki/Bn/kiBnNejo0JW0. Notice that the link is: https://video.parler.com/ followed by the first two characters of the video ID, then /, then the next two characters, another /, and the video ID.

But if you click on this, you will get an error.

This is because the Parler video servers are still running (as of January 12) but the Domain Name System (DNS) is not running.

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:

I'm writing these instructions against OF 0.9 but this should work on 0.9.3, etc.

so the general idea behind making a dylib is to do this:

in the case of OF, it's something like:

Instructions for making a Neural-Style movie

The following instructions are for creating your own animations using the style transfer technique described by Gatys, Ecker, and Bethge, and implemented by Justin Johnson. To see an example of such an animation, see this video of Alice in Wonderland re-styled by 17 paintings.

Setting up the environment

The easiest way to set up the environment is to simply load Samim's a pre-built Terminal.com snap or use another cloud service like Amazon EC2. Unfortunately the g2.2xlarge GPU instances cost $0.99 per hour, and depending on parameters selected, it may take 10-15 minutes to produce a 512px-wide image, so it can cost $2-3 to generate 1 sec of video at 12fps.

If you do load the

ffmpeg

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:
