* ffi req * handle req_id * remaining room events * fix * Update ffi.proto * use sid instead of info * state -> stream_state * "s" * participant is optional on data received * add ReleaseHandleRequest * Update ffi.proto * add DataPacketKind * VideoSinkInfo * append info It looks nicer on the FFI languages * wip * keep it simple * Update ffi.proto * update server to latest proto * to_i420 * i420_to_abgr * to_argb * add publications to ParticipantInfo It'll be used when we join a Room * cleanup + DisposeRequest * fix compilation * send the whole buffer info with to_i420
