Not certain this is your issue, but there are multiple different protocols that support Bluetooth audio. The first is A2DP, where the phones audio is sent to a speaker or other device as an audio sink. This is what is mostly used for multimedia. The other that could be the issue is HFP which is the protocol mostly used for headsets with microphones. Its been a long time since I’ve worked on Bluetooth, but I have faint memories of having similar issues when the Hands Free Profile was selected instead of A2DP to manage the connection.

Good catch on Redhat. That is a family I’ve never used. Out of the ones I’ve used Pacman was my favorite, but Nix has been pretty good to me so far as well. I’ll have to try out a dnf system next

Seems like Mint is the consensus and I don’t disagree. Just some things to consider when choosing:

1. Desktop Environment/Window Manager (DE/WM) this is the software responsible for displaying your desktop and managing the opening and closing of graphical windows. Window managers are very bare-bones and might offer an experience significantly different than Windows. (See tiling WMs). Desktop environments do the same and more, and are often bundled with launchers and useful default programs like terminals and editors.

2. Package manager. Package managers are responsible for managing your installed software. There are a variety of options, and distros typically will choose one as their default. Pacman for Arch, Aptitude for Debian, RPM for RedHat, and others. These are mostly interchangeable for the end user, but each has slightly different commands and frontends. So just be aware there will be a bit of an extra learning curve moving from a distro that uses one to a distro that uses another.

3. Release cycle. Different distros offer different styles of releasing updates. Ubuntu and Debian periodically release updates in a cycle with major and minor releases. Some releases are marked for long term support and others marked as short term. Upgrading releases has been hit or miss for me, so I prefer rolling release distros. These distros don’t distinguish major releases and simply upgrade in place. Each has it’s own advantages, just be mindful of how often you will have to upgrade.

That and more really. You could use it to do a green screen effect, but you can also use it to adjust color balance, brightness or do weirder things like swapping values between colors. It gets really crazy when you are working with full video because the time of the current frame is also available to be incorporated, so you can even do animated effects.

Another powerful filter is the convolve filter. That allows you to apply matrix transformations, which can for example be used to apply a homography matrix and adjust a videos perspective.

Well for instance you can use it to apply tranparencys or other effects using the geq filter. It applies a formula to every pixel in the input and can adjust alpha, rgb values, and gamma. You can also use conditionals in your formula and have access to the current pixels location and value, so you can apply your transforms only to specific regions if you want, or do an adjustment keyed only to a specific color.

Ffmpeg has been such cool software to learn. Simple filter chains can do incredible things
