#
# Recipe to build a container image for dash-mpd-cli + helper applications, for Linux/arm/v7.
#
# 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_armv7 --platform linux/arm/v7 --tag dash-mpd-cli-linux-armv7 --manifest dash-mpd-cli .
# static build of MP4Box from GPAC, which is not packaged for Alpine Linux.

# shaka-packager needs a few tweaks to build from source. We see C compiler errors when building

# We work around a C compiler error when building the c-ares third party library, which doesn't
# build due to -Werror=shift-count-overflow errors from -Werr. We need to modify CMakeLists.txt
# to remove the -Werror and add a definition for _LARGEFILE64_SOURCE which is needed while
# compiling the abseil-cpp dependency.
