Hello everyone!
I am running OpenCV 2.4.7, compiled on 64 bit Ubuntu 12.04.
I can read video files just fine (cv2.VideoCapture).
However, using any codec with cv2.VideoWriter yields the following error:
error: /home/-----/opencv-2.4.7/modules/highgui/src/cap_gstreamer.cpp:505: error: (-210) Gstreamer Opencv backend doesn't support this codec acutally. in function CvVideoWriter_GStreamer::open
Does anyone know what could be causing the problem? Is it a gstreamer version error or something?
Below is the output of cmake for this opencv install:
