# punktfunk host configuration (Windows) — read by the `PunktfunkHost` service.
#
# `punktfunk-host service install` writes a default copy of this to
#   %ProgramData%\punktfunk\host.env
# Edit that file (not this one) and restart the service to apply:
#   punktfunk-host service stop
#   punktfunk-host service start
#
# Format: KEY=VALUE per line; '#' starts a comment. The service loads these into its environment
# and passes PUNKTFUNK_* and RUST_LOG through to the host it launches into the active session.

# Hardware encode backend. `auto` (default) detects the GPU vendor: NVIDIA->nvenc (direct SDK),
# AMD->amf, Intel->qsv (both libavcodec). Force one with: nvenc | amf | qsv | sw (software H.264).
# nvenc needs the `--features nvenc` build; amf/qsv need the `--features amf-qsv` build (FFmpeg DLLs
# ship in the installer). The published installer is built with all three.
PUNKTFUNK_ENCODER=auto

# Video source: `virtual` creates a per-client virtual display at the client's exact resolution +
# refresh — the flagship mode. Requires the bundled pf-vdisplay indirect display driver installed.
PUNKTFUNK_VIDEO_SOURCE=virtual

# Virtual-display backend: `pf` = the all-Rust pf-vdisplay IddCx driver the installer bundles (the
# shipped driver; leave as the default). `sudovda` selects the legacy backend if one is present.
PUNKTFUNK_VDISPLAY=pf

# Capture straight from the pf-vdisplay driver's shared ring — the validated zero-copy path (incl. the
# secure desktop). Falls back to DDA if the driver can't attach. Set to 0 to force WGC/DDA capture.
PUNKTFUNK_IDD_PUSH=1

# Capture the secure desktop (UAC / lock / login) so the stream survives those transitions.
PUNKTFUNK_SECURE_DDA=1

# Log level (info | debug | trace). Logs land in %ProgramData%\punktfunk\logs\.
RUST_LOG=info

# The host subcommand the service launches. Default: `serve --gamestream` (native punktfunk/1 host
# ALWAYS on + the GameStream/Moonlight-compat planes). Use `serve` for a SECURE native-only host
# (no plain-HTTP pairing / legacy GCM nonce reuse — security-review #5/#9). Uncomment to override.
#PUNKTFUNK_HOST_CMD=serve --gamestream

# Multi-GPU boxes only: force the NVENC/Desktop-Duplication GPU by Description substring. Leave
# unset on single-GPU machines (the default auto-picks the discrete adapter).
#PUNKTFUNK_RENDER_ADAPTER=4090

# Keep a per-client virtual display alive briefly after disconnect so a quick reconnect reuses it
# (no display connect/disconnect chime). Default 10000 ms.
#PUNKTFUNK_MONITOR_LINGER_MS=10000
