  • Component changed from FFmpeg to build system

Replying to cehoyos:

Could you test attached patch?

Ok! your patched worked!, compiled ok...
haven't done any other testing though..


comment:4 Changed 5 years ago by saste

Patch looks OK, but we should possibly do a check on the libopencv version in configure, and require a version which supports the new interface (I don't know when cxcore.h replaced cxtypes.h).

comment:5 Changed 5 years ago by greybones

Ok last opencv revision to support cxtypes.h was 3059.. its gone in 3060

Versions prior to 2.1.0 I think..

perhaps your more skilled at browsing their svn than I am...

vf_libopencv: prefer opencv/cxcore.h over cxtypes.h

Require the presence of opencv/cxcore.h in place of opencv/cxtypes.h,
which has been removed. Fix compilation with libopencv > 2.1.0.

Fix trac issue #221.
