# Tier 4 item 4.6 session 105 B: real gstreamer-rs software encoder pipeline.
# Pulls gstreamer, gstreamer-app (appsrc / appsink), gstreamer-video (video
# caps helpers), and glib (BoolError, ObjectExt). Host must have the
# GStreamer 1.22+ runtime with `gst-plugins-base`, `gst-plugins-good`,
# `gst-plugins-bad`, `gst-plugins-ugly`, and `gst-libav` installed; install
# recipes live in `tracking/TIER_4_PLAN.md` section 4.6. Default OFF so CI
# runners without GStreamer continue to build the scaffold + pass-through.

# Tier 4 item 4.6 session 156: VideoToolbox HW encoder backend on macOS.
# Implies `transcode` (the new module reuses gstreamer-rs); additionally
# requires the `applemedia` plugin from gst-plugins-bad which ships
# `vtenc_h264_hw`. Default OFF so non-mac builds (and macos builds that
# stick to x264) do not pay the gstreamer-bad applemedia surface. Install:
# `brew install gstreamer gst-plugins-bad` (or the official .framework
# installer at https://gstreamer.freedesktop.org/download/).
