revind / revind.so / run / websockify 는 websockify 에서 나온거
libvncserver 와 noVNC와 websockify 의 조합으로 어찌 되긴 하는데..

인자는 아래와 같이 하고 실행!
$ ./run 5900 -- ./example
웹 브라우저에서 http://ip:5800 으로 접속하면 아래와 같이 뜨고
별다른 설정을 하지 않았다면 wss(websocket secure)를 안될테니 위에 "Click here to connect using noVNC"를 누른다.
약간의 시간을 기다리면(libvncserver의 웹 서버가 느린지 파일 전송이 좀 느리다)
아래와 같이 쨘~
+
한번 되더니 websockify 없이도 되네.. 머지?

runInBackground 의 값을 TRUE 로 해주면 웹 서버가 작동을 안한다 -_-
어떻게 해야 할까..
void rfbRunEventLoop ( rfbScreenInfoPtr screenInfo, long usec, rfbBool runInBackground )
static THREAD_ROUTINE_RETURN_TYPE listenerRun(void *data) { rfbScreenInfoPtr screen=(rfbScreenInfoPtr)data; int client_fd; struct sockaddr_storage peer; rfbClientPtr cl = NULL; socklen_t len; fd_set listen_fds; /* temp file descriptor list for select() */
/* Only checking socket state here and not using rfbIsActive() because: When rfbShutdownServer() is called by the client, it runs in the client-to-server thread's context, resulting in itself calling its own the pthread_join(), returning immediately, leaving the client-to-server thread to actually terminate _after_ the listener thread is terminated, leaving the client list still populated. */ /* TODO: HTTP is not handled */ }
rpi3 같은 메모리 대역폭 후달리는 애도 잘 쓰도록 만들었다는데 머.. 3.3%면 양호한건가..
sway가 문제인가?
The OpenGL ES 2.0 based renderer has now been replaced with a pixman based renderer. The new renderer is both simpler and performs better on devices with poor memory bandwidth such as the Raspberry Pi 3.

In thephysical sciences, thewavenumber(orwave number), also known asrepetency,[1]is thespatial frequencyof awave, measured incyclesper unit distance (ordinary wavenumber) orradiansper unit distance (angular wavenumber).
