I've been trying to compile OpenCV3 beta for Debian Jessie, but I can't figure out how to compile support for video I/O .
Tutorials that can be found on-line usually use ffmpeg library, but as I found out Debian 8 replace this library with libav (?).
Of course I found tutorials how to remove libav and install ffmpeg, but I would rather try to find some another way.
I use OpenCV3 beta from http://opencv.org/
When I use this switch
Code: Select all
-DWITH_FFMPEG=0When I don't use that switch, then I get this error:
Code: Select all
