Unable to open mp4 video file with VideoCapture before and after recompiling with ffmpeg

It all started when I tried to run a program like this: VideoCapture cap; cap.open("GOPR3252.mp4"); if(!cap.isOpened()) { return -1; } I couldn't open the video, even though I tried to manually add the codec CV_FOURCC('A', 'V', 'C', '1'). I read that this may be due to the link with ffmpeg. So I compiled and installed ffmpeg using [this guide](http://answers.opencv.org/question/63331/opencv-30-wont-compile-with-ffmpeg-support/) and [this one](http://stackoverflow.com/questions/31663498/opencv-3-0-0-make-error-with-ffmpeg). Later, I uninstalled OpenCV, downloaded and compiled using CMake as: > cmake -D CMAKE_SHARED_LINKER_FLAGS=-Wl,-Bsymbolic -D WITH_FFMPEG=ON -D WITH_QT=ON -D BUILD_EXAMPLES=ON CMAKE_BUILD_TYPE=Release /route_to_software/opencv/ However, all the time I get this in the resume at the video section: -- Video I/O: -- DC1394 1.x: NO -- DC1394 2.x: NO -- FFMPEG: NO -- codec: NO -- format: NO -- util: NO -- swscale: NO -- resample: NO -- gentoo-style: NO -- GStreamer: NO -- OpenNI: NO -- OpenNI PrimeSensor Modules: NO -- OpenNI2: NO -- PvAPI: NO -- GigEVisionSDK: NO -- UniCap: NO -- UniCap ucil: NO -- V4L/V4L2: NO/YES -- XIMEA: NO -- Xine: NO -- gPhoto2: NO -- I have no problem making and installing OpenCV, but I still can't open that video. Then, I tried to convert the video from mp4 to avi and got this error when reading the video file: > Unexpected list type. Expected: hdrl. Got: movi. I am running out of ideas. Any clue what I am doing wrong? I am using OpenSUSE 13.2 Thanks in advance,
