# Runtime-образ для cuframes — содержит:
#  - libcuframes.so (built из dev-stage)
#  - cuframes-rtsp-source bin
#  - sub_count example bin
#  - минимальный CUDA runtime + ffmpeg libs (без nvcc и headers)
#
# Не для разработки! Для dev — docker/Dockerfile.dev.
#
# Build:
#   docker build -f docker/Dockerfile.runtime -t gx/cuframes:0.1 .
#
# Run (publisher):
#   docker run --rm -it --runtime=nvidia --ipc=shareable \
#     -v cuframes_sock:/run/cuframes \
#     gx/cuframes:0.1 \
#     /usr/local/bin/cuframes-rtsp-source --rtsp ... --key ...
