A newer release is available: https://github.com/Xaymar/obs-studio_amf-encoder-plugin/releases/latest

Once again back to change things around, the multi-GPU code has finally been rewritten and properly implemented - which means that DirectX 11 and DirectX 9 are now fully supported. So rejoice Windows 7 users, you can now choose which GPU the encoding should take place on (with the limitation that a Monitor must be connected)! Needless to say, this change removes the old multi-GPU selection properties with the new revamped ones: 'Video API' and 'Video Adapter'.

Some changes to the available properties and internal logic have also been done. Properties are now reordered to be closer to the order they are applied in, some properties have been renamed and the 'Master' view mode has grown quite a bit. 'Frame Skipping' no longer defaults to being enabled, 'B-Frame QP' is now properly hidden, 'Profile' now has two new options ('Constrained Baseline' and 'Constrained High'), 'Video Adapter' and 'OpenCL' are now properly hidden and changing 'Preset' should now properly reset property states. Also 'Unlock Properties' was removed due to it causing more issues that it was worth.

Some changes were also done internally to make the plugin run better. Startup log output has been reduced to one line at the request of people handling support, a crash with very high Keyframe Intervals has been fixed and the frame queue has been reduced from 3 seconds to 1 second.

One major change was done to how frames are submitting and packets are retrieved and that is that the plugin will now attempt to submit a frame or retrieve a packet for a specific amount of time (1000/framerate milliseconds) before giving up. Due to this change OBS will now show the 'Encoding overloaded' message when the encoder is overloaded.

Hotfix 1: Support for older drivers has been fixed again.
Hotfix 2: Fix certain log messages being displayed wrong and handle broken Direct3D 11 installations.

Notes

This change includes renaming some properties so some settings might be lost and have to be set again (B-Frames, Experimental Properties). Please revalidate your settings or even create a clean profile to work off of.
