libcast is an open source implementation of the Cast procotol supporting Cast applications and streaming to Cast-compatible devices.
To run the standalone sender and receivers together, first you need to install the following dependencies: FFMPEG, LibVPX, LibOpus, LibSDL2, as well as their headers (frequently in a seperate -dev package). From here, you need to generate a RSA private key and create a self signed certificate with that key.
From there, after building Open Screen the cast_sender and cast_receiver executables should be ready to use:
$ /path/to/out/Default/cast_sender -s <certificate> <path/to/video> ... $ /path/to/out/Default/cast_receiver <interface> -p <private_key> -s <certificate>
When running on Mac OS X, also pass the -x flag to the cast receiver to disable DNS-SD/mDNS, since Open Screen does not currently integrate with Bonjour.
When connecting to a receiver that's not running on the loopback interface (typically lo or lo0), pass the -r <receiver IP endpoint> flag to the cast_sender binary.
An archive containing test running scripts, a video, and a generated RSA key and certificate is available from google storage. Note that it may require modification to work on your specific work environment:
