I see those handled in code: else if( !strcmp(argv[i], "-z") ) { start_remote_control = 1; } but i don't have remote for testing this .... else if( !strcmp(argv[i], "-b") ) { operation = DO_BRENDER; if( i > argc - 2 ) { fprintf(stderr, _("-b may not be used by the user.\n")); exit(1); } else strcpy(deamon_path, argv[i + 1]); I think this one start background render mode? Apparently, it want socket, so I can run it like /bin/cin -b /tmp/cinelerra.01e3ad92-6020-4d7c-b862-a8fa9d9d8917 but of course it will show nothing in gui, just: ../bin/cin -b /tmp/cinelerra.01e3ad92-6020-4d7c-b862-a8fa9d9d8917 RenderFarmClient::main_loop: client started ^Csignal_entry: got SIGINT my pid=17867 execution table size=0: signal_entry: lock table size=1 lock_items: 0 lock_frees: 1 SigHandler::signal_handler total files=0 Аварийный останов I CTRL_C it .... not sure if this specific option actually *that* interesting for end-users ... But one about starting in remote control mode (?) might be useful? ...time to look into this remote android protocol submodule . may be it can be extended for allowing save operation from remote device, so periodic backups can be triggered externally (just idea at this moment ) .....
