Summary:        L4S Chromium integration: Fedora Chromium with Tegra NVDEC hardware video decoding

# Fedora's chromium links the system ffmpeg (libavcodec-free), which on L4S ships
# the nvv4l2 NVIDIA V4L2 decoders registered ahead of the software ones, so
# chromium gets hardware video decode for free. The only extra needed is to run
# chromium with --no-sandbox so the renderer can open /dev/nvhost-nvdec (the
# sandbox otherwise blocks that device, falling back to software decode).
Requires:       chromium
Requires:       libavcodec-free
# /dev/nvhost-nvdec + the libv4l2 nvvideocodec plugins come from the BSP/configs
Requires:       nvidia-l4t-bsp

%description
%{summary}.

This package turns Fedora's Chromium into the L4S hardware-accelerated browser:
it enables NVDEC video decode (via the nvv4l2 system ffmpeg) by disabling the
Chromium sandbox so the GPU process can reach /dev/nvhost-nvdec, and adds the
"Chromium Streaming" launcher (Chrome OS user-agent) for cloud gaming.
