    Hello,

    I’m using the latest version of NoMachine 8.11.3 (free version) on macOS 14.5 with AMD RX series video adapter and I’m unable to activate HW encoding while the rest of the system is able to utilize it without problem (QuickTime export to both H264 and HEVC and other video encoders). This is the host side.

    The Mac has a display connected however, in the logs I found a reference that the server runs in a headless mode.

    The client (remote) side is a Windows 11 machine and when I connect to the Mac, on the connection status I can see: SW encoding, H264 / HW decoding, DXVA

    As I understood from the documentation, HW encoding for AMD adaptors on Mac should be supported since NoMachine 8 version release. Or am I mistaken? If not, help me please 🙂

    Hi, we checked the logs and we see that encoding fails at a very early stage, at a point where it seems unlikely that it can be a NoMachine issue. Can you confirm in any way that the other apps you mention are using HW encoding and not a SW fallback? How have you checked that they are using HW encoding?

    Hi,

    As I mentioned, one method I used to verify this was through the QuickTime export option for both H264 and HEVC formats. A test video of 5 minutes was converted to H.264 in approximately 3 minutes and to HEVC (H.265) in 5 minutes, with minimal CPU usage and significant GPU load (monitored using the iStat Menus application). A CPU-only conversion would have taken considerably longer. These conversion times are more typical for modern 8-core CPUs that utilize all 16 threads, not for my outdated 4-core Xeon CPU that is 14 years old.

    Additionally, I confirmed this with VideoProc Converter, which includes a tool to check if the GPU can be used for video conversion. I have attached a screenshot as evidence.

    If you know of a better method to verify this, please inform me, and I will test it myself.
