Updating FFmpeg

Windows

To grab the newest version of FFmpeg, head to BtbN's Windows FFmpeg builds and grab the one that ends with "-win64-gpl.zip".

Find your AppData\Roaming directory

Once downloaded, hit "⊞ Win + R" (aka "Run") and type in "%APPDATA%" and hit "OK". This will bring you to a folder named "C:\Users{your username}\AppData\Roaming" (replace "{your username}" with whatever appears for you). If a folder called FFmpeg does not exist, create it here. If there is already folders inside of this folder, delete them.

Extract the contents of the zip folder

In another window, double click on the zip folder to open it. There should be a single folder named something like "ffmpeg-N-numbers-gibberish-win64-gpl", click into that folder and you should then see a "bin" and a "doc" folder. Copy them to "C:\Users{your username}\AppData\Roaming\FFmpeg."

Set the PATH variable (optional)

FastFlix will automatically look here for FFmpeg. But if you want to easily be able to access it from the command line at any point, you will need to add the folder ""C:\Users{your username}\AppData\Roaming\FFmpeg\bin" (notice the "\bin" on the end) to the PATH.

Linux / Mac

To get HDR10+ support or all the possible encoders, you will most likely have to compile it yourself (godspeed), for a 80% solution, you can download Linux static builds or MacOS static builds. Once downloaded, extract them to a folder in your home directory of your choice, and add them to the FastFlix config file.
