Línea de trabajo

Reproduce la fase de pruebas del encoder de sunshine.exe con la RTX 4060 indicada e inspecciona la ruta de NVENC a la que se llega después de “Creating encoder [hevc_nvenc]” para la salida SDR Rec. 709 10-bit. Compárala con los intentos de encoder precedentes para H.264, HEVC, AV1 y yuv444. Se considera terminado cuando la prueba HEVC 10-bit tiene éxito o falla correctamente sin provocar un bloqueo del proceso, manteniendo el comportamiento de fallback.

Describe the Bug

Describe the bug
Sunshine crashes with an access violation (c0000005) in nvcuda64.dll every time it tries to create the second-pass HEVC 10-bit NVENC encoder during the encoder testing phase. This happens consistently, even when running sunshine.exe manually (not as a service).

To Reproduce

  1. Run sunshine.exe (manually via cmd, or via service)
  2. Sunshine successfully creates: H.264 (8-bit), HEVC (8-bit), AV1 (8-bit), H.264 yuv444
  3. Crashes immediately when creating HEVC 10-bit encoder (Color coding: SDR Rec. 709, Color depth: 10-bit)

Expected behavior
Sunshine should either successfully create the 10-bit encoder, or fail gracefully and fall back to another encoder, instead of crashing the entire process.

System info

  • GPU: NVIDIA GeForce RTX 4060 (Desktop)
  • OS: Windows 10 Pro 22H2
  • Sunshine versions tested: v2025.628.4510 and v2025.924.154138 (both crash identically)
  • NVIDIA drivers tested: 616.56, 591.74 (both crash identically, ruling out driver issue)
  • Also tried: full DDU clean uninstall + reinstall, still crashes
  • Workaround: setting encoder = software in sunshine.conf avoids the crash entirely

Crash details (from Windows Event Viewer, Application Error)

  • Faulting module: nvcuda64.dll
  • Exception code: 0xc0000005
  • Consistent across all 3 driver versions tested (32.0.16.1656, 32.0.15.9597, 32.0.15.9174)
