#        -*- Dockerfile -*-
#
# Recipe to build a container image for dash-mpd-cli + helper applications, for Linux/ppc64le.
#
# This Containerfile contains the recipe needed to generate a docker/podman/OCI container image
# including the dash-mpd-cli binary alongside the external helper applications that it uses for
# muxing media streams, for extracting/converting subtitle streams, and for decrypting content
# infected with DRM. These are packaged with a minimal Alpine Linux installation.
#
# To build the container locally (not needed for an end user)
#
#   podman manifest create dash-mpd-cli
#   podman build -f etc/Containerfile_linux_ppc64le --platform linux/ppc64le --tag dash-mpd-cli-linux-ppc64le --manifest dash-mpd-cli .


# We build shaka-packager from source, because it's not packaged for Alpine Linux and not
# distributed in binary form for ppc64le by upstream. It doesn't build on Alpine Linux (with musl-libc)
# due to a missing function definition concerning UnscaledCycleClock::Frequency() used by the
# third-party library abseil-cpp. We build on Debian instead and link statically with glibc.
