Improved

• Naming changed to not cause issues with other addons;
• Workflow switched to Ubuntu to give better support for older distro’s;

Deleted

• Removed MacOS x86_64 support (arm64 is sufficient);
• Hardware decoding; I feel that I should mention why I decided to remove that part. It mainly has to do with the fact that it wasn’t working correctly as performance was slower due to the copying of data between the CPU and GPU memory which was happening too often. This is possible to be fixed, but will be time consuming to get it working correctly and for every platform. Windows already had no support when it was included, so this won’t be a big loss. I may tackle this again in the future once I figure out how to directly access memory in the GPU to create a texture from that memory instead of having to copy from GPU -> CPU -> GPU, but again that’s a problem for later.
