Whether you play games, create content, or develop software, Metal 2 provides the power to bring your imagination to life. Now Metal 2 not only takes the visual experience to the next level, but also adds capabilities like machine learning, virtual reality, and external GPU support for entertainment and professional creative apps.
Metal is a technology built into macOS that allows apps to unleash the full power of the GPU. And GPUs are becoming more and more powerful. Today’s Mac experience relies more than ever on the graphics processor (GPU) in your computer. Using HEVC, videos stream better and take up less space on your Mac, while preserving the same visual quality. With the rising popularity of 4K video, a new industry standard arrives on Mac - HEVC (High Efficiency Video Coding, also known as H.265).1 It can compress video up to 40 percent more than H.264, the current standard for video compression. With macOS High Sierra, we’re introducing the Apple File System to every Mac with all‑flash internal storage, with an advanced architecture that brings a new level of security and responsiveness. But today’s flash‑based Mac systems open up new possibilities for innovation, so it’s time to lay a new foundation. Our current file system was designed in the early days of Mac, and it has performed beautifully ever since. And a file system is what organizes all that data into files and folders you can access with a click. To your Mac, everything you care about is data.
From rearchitecting how it stores your data to improving the efficiency of video streaming to unleashing the full power of your graphics processor, it’s all central to today’s Mac experience. Yes this seems to be a more recent issue.Īt this point i can't figure out what may be causing the frame rate issues as performance doesn't seem to be a problem on the machine.MacOS High Sierra introduces new core technologies that improve the most important functions of your Mac. Please share your experiences and suggestions.
Is there a way of using Intel Encoding on the mac rather then Apples VT hardware encoder. Is there anyway to enable or fix Hardware Acceleration? Anyways to diagnose the Apple VT H264 Hardware Encoder?
Is there a bug in the latest OBS version for running on Mac OS X High Sierra?
Even managed to install Logitechs latest driver for Mac on its website which hasn't helped the issue. My user is using a C922C Logitech webcam on USB 3.0 ports.
Trying to stream to 720p 5000kbps CBR with NV12 color space and the usual proper encoder settings for H264 (main, none, etc.) Users reported audio was out of sync with the video which tells me that the framerate is still not working correctly. No networking issues were a problem and Youtube reported good stream performances. I tried various buffering rates.īitrate was set to 5000 bitrate CBR.
CPU usage was around 10% idle and 30% while streaming but the stream clearly was not keeping up with the intended frame rates. doesn't matter what framerates, color settings etc seemed to only get the performance to below the proper frame rates at around 20-23 fps while idle (ie not streaming).
I then tried working around the hardware encoding by using H264 settings. I was able to get it working again but soon found out it was because of the hardware acceleration is not working properly. First time fixed the starting problem of the app. Library/Application Support/obs-studio folder. I tried going back to previous versions, wiping the old OBS installation, running the cleaner and starting over as well as renaming the entire. This started happening after the user upgraded the OBS version to the most current version.ĬCleaner app was run and cleaned up a lot of garbage on the machine as well which seemed to fix things a bit. Spent the last 6-7 hours tackling a difficult OBS issue on a Mac Retina 13-inch Mid 2014 laptop after OS was recently updated to Mac OS High Sierra 10.13.6 and When the latest version of OBS got updated to version 22.0.1.Įvery time "Apple VT H264 Hardware Encoder" was used the OBS install would crash after starting with a pretty ugly kernel/memory dump error report.
