OBS Studio 28.1 Beta 1

28.1 Changes
------------
* Added NVENC AV1 hardware encoder on Windows [Jim]

  * Note: Currently only works with the NV12 (OBS default) and P010 color formats
  * Note: Currently does not support the "rescale" feature in advanced output mode
  * Note: Only available for 4xxx+ series video cards from NVIDIA

* Updated NVENC presets [Jim]

  * Presets have been split into 3 different settings: Preset, Tuning, and Multipass mode
  * Presets are now P1-P7, lower being lower quality, higher being higher quality. Note that higher presets may incur a higher hit on GPU usage which may impact the performance of games running simultaneously with OBS.
  * Tuning is used to determine whether to prioritize latency or quality. It has three settings: High Quality, Low Latency, and Ultra Low Latency.
  * Multipass Mode is used to determine whether a second pass is used in encoding, and has three settings: Disabled, Quarter Resolution, and Full Resolution. Enabling this will give higher quality at the cost of more GPU usage, which may impact the performance of games running simultaneously with OBS.

* Fixed a bug where Direct3D 9 games stopped capturing properly with game capture on Windows 11 22H2 [Rodney]
* Moved "Always on Top" to the View menu [gxalpha]
* You can now select a source individually for the Virtual Camera [chippydip]
