Hello,
Based on documentation cast_shell should be run easily: https://chromium.googlesource.com/chromium/src/+/HEAD/docs/linux/cast_build_instructions.md#Run-cast_shell
However this returns error:
ERROR:chromecast/cast_core/runtime/browser/runtime_service_impl.cc:63] Runtime id must be specified in command line with: --cast-core-runtime-id
With those switches cast_shell is started:
out/cast/cast_shell \
--cast-core-runtime-id=1 \
--runtime-service-path="localhost:9000" \
--cast-mojo-broker-path=unix:/tmp/cast_mojo_broker \
--ozone-platform=x11 \
out/cast/cast_shell \
--cast-core-runtime-id=1 \
--runtime-service-path="localhost:9000" \
--cast-mojo-broker-path=unix:/tmp/cast_mojo_broker \
--ozone-platform=x11 \
However in this state cast_shell is by default is idle state. I see browser, gou and zygote processes, but renderer process is not created, so we have only a black screen.
How can I inject URL into cast?
From my understanding Cast runtime service is responsible for app launch. I need to send some gRPC request for it?
