I am unable to import cv2 in python 3.4 due to the below error, it works fine with Python2.7 and also on my laptop in python3.4 but the server im using gives:
Python 3.4.2 (default, Oct 8 2014, 10:45:20)
[GCC 4.9.1] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
File "", line 1, in
ImportError: /opt/local/opencv/3.1/lib/libopencv_videoio.so.3.1: symbol av_image_get_buffer_size, version LIBAVUTIL_54 not defined in file libavutil.so.54 with link time reference
I have compiled with ffmpeg on and have the following libav packages installed:
ii libavc1394-0:amd64 0.5.4-2
ii libavcodec-dev 6:11.7-1~deb8u1
ii libavcodec56:amd64 6:11.7-1~deb8u1
ii libavformat-dev 6:11.7-1~deb8u1
ii libavformat56:amd64 6:11.7-1~deb8u1
ii libavresample-dev 6:11.7-1~deb8u1
ii libavresample2:amd64 6:11.7-1~deb8u1
ii libavutil-dev 6:11.7-1~deb8u1
ii libavutil54:amd64 6:11.7-1~deb8u1
When I run ldd -r libopencv_videoio.so.3.1 I see the following errors:
symbol av_image_get_buffer_size, version LIBAVUTIL_54 not defined in file libavutil.so.54 with link time reference (./libopencv_videoio.so.3.1)
symbol avformat_get_mov_video_tags, version LIBAVFORMAT_56 not defined in file libavformat.so.56 with link time reference (./libopencv_videoio.so.3.1)
symbol av_image_fill_arrays, version LIBAVUTIL_54 not defined in file libavutil.so.54 with link time reference (./libopencv_videoio.so.3.1)
Looks similar to the below however the link to the solution is no longer working:

Same packages and versions installed on my laptop which is fine, both using Debian Jessie. Any suggestions very welcome!
Cheers
