mjpg-streamer 컴파일 및 설치

$ sudo make install
install --mode=755 mjpg_streamer /usr/local/bin
install --mode=644 input_ov5640.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_ov5640.so

input_ov5640.so

mjpg-streamer의 input_uvc.so는 YUV만 지원하고, BPI-M2 ZERO의 카메라인 OV5640는 YUV420코덱만 지원하기 때문에, mjpg-streamer에서 사용 할 수 없습니다.

제가 작업한 OV5640의 YUV420코덱을 지원하는 so 파일을 공개 합니다.
BPI-M2 ZERO의 카메라인 OV5640를 사용해서 mjpg-streamer로 스트리밍 하시려면 첨부한 파일을 사용하세요.
