# Hardware transcoding for Collectoh in Docker — https://collectoh.com/docs/playback/

#   docker compose -f docker-compose.yml -f docker-compose.gpu.yml up -d
#
# Intel Quick Sync and AMD (VAAPI) need only the render device and its group. The group id
# differs between distributions — run `getent group render | cut -d: -f3` on the host and put
# it in .env as RENDER_GID. A wrong group is the usual reason hardware transcoding "doesn't
# work"; Collectoh's Diagnostics page says so and names the fix.

# NVIDIA needs the NVIDIA Container Toolkit on the host; uncomment the environment and deploy
# blocks below.
