mjpg-streamer 컴파일 및 설치
출처 : http://www.lavrsen.dk/svn/motion/tags/3.2.9/picture.c
$ svn co https://svn.code.sf.net/p/mjpg-streamer/code/mjpg-streamer mjpg-streamer $ cd mjpg-streamer $ make USE_LIBV4L2=true clean all $ sudo make install install --mode=755 mjpg_streamer /usr/local/bin install --mode=644 input_ov5640.so input_gc2035.so input_uvc.so output_file.so output_udp.so output_http.so input_testpicture.so input_file.so /usr/local/lib/ install --mode=755 -d /usr/local/www install --mode=644 -D www/* /usr/local/www
input_gc2035.so
input_gc2035.tar.gzmjpg-streamer의 input_uvc.so는 YUV만 지원하고, Orange PI PC2의 카메라인 GC2035는 YUV420코덱만 지원하기 때문에, mjpg-streamer에서 사용 할 수 없습니다.
제가 작업한 GC2035의 YUV420코덱을 지원하는 so 파일을 공개 합니다.
Orange PI PC2의 카메라인 GC2035를 사용해서 mjpg-streamer로 스트리밍 하시려면 첨부한 파일을 사용하세요.
