OBS Studio 28.1 Released With Various Fixes, Updated NVENC Presets
Back in September was the release of OBS Studio 28.0 with 10-bit and HDR video encoding, ported to the Qt6 tool-kit, and many other big enhancements. OBS Studio 28.1 isn't quite as significant but does have a few goodies.
Most notable with OBS Studio 28.1 is adding support for NVIDIA NVENC AV1 hardware video encoding for use with the new GeForce RTX 40 series GPUs. However, this NVENC AV1 hardware encode with OBS Studio is initially limited to Windows. Those with NVIDIA RTX 40 hardware on Linux will need to wait for a latter OBS Studio release for the AV1 accelerated video encode there. The initial OBS Studio implementation also currently only works with NV12 and P010 color formats.
Some of the other OBS Studio 28.1 work that isn't Windows specific include various NVIDIA NVENC preset updates, the ability to set a specific source for the virtual camera, appearance issues with the stats widget, fixing the blend method in the studio mode, and various other fixes.
