# The upstream `helium` launcher is a plain Nix wrapper that ignores any
|

# *-flags.conf file (that convention is Arch-specific, not NixOS). So to
|
|
# actually pass command-line flags we re-wrap the launcher here.
|
|
#
|
|
# Flag names verified against this Helium build's binary strings.
|
|
# - AcceleratedVideoDecodeLinuxGL / ...ZeroCopyGL: the VA-API GL decode
|
|
# path (renamed from the old Vaapi* names, which are no-ops here).
|
|
# - VaapiOnNvidiaGPUs: required. Chromium disables VA-API on NVIDIA by
|
|
# default and hard-skips the nvidia-drm device ("Should skip nVidia
|
|
# device named: nvidia-drm" in the logs); this re-enables it, routing
|
|
# decode to NVDEC through the nvidia-vaapi-driver bridge.
|
|
# - VaapiIgnoreDriverChecks: bypass the driver allowlist.
|
|
# HEVC decode itself needs no runtime flag in this build (enable_platform_hevc
|
|
# is compiled in and on by default). Wayland-only: the NVIDIA VA-API path
|
|
# is broken under X11. Upstream considers nvidia-vaapi-driver unsupported,
|
|
# so confirm via chrome://media-internals (decoder should read VaapiVideoDecoder).
