Tôi đã cài đặt OpenCv 2.3.1 trong raspberry pi (Debian Wheezy) theo hướng dẫn này.
Nhưng tôi không thể quay video bằng webcam USB. Guxer hiển thị lỗi này:
OpenCV Error: Unsupported format or combination of formats (Gstreamer Opencv backend doesn't support this codec acutally.) in CvVideoWriter_GStreamer::open, file /home/pi/OpenCV-2.3.1/modules/highgui/src/cap_gstreamer.cpp, line 483 terminate called after throwing an instance of 'cv::Exception' what(): /home/pi/OpenCV-2.3.1/modules/highgui/src/cap_gstreamer.cpp:483: error: (-210) Gstreamer Opencv backend doesn't support this codec acutally. in function CvVideoWriter_GStreamer::open Aborted
Tôi có thể làm gì tiếp theo?
