#37314: opencv @2.3.1: error: ‘av_open_input_file’ was not declared in this scope -------------------------+------------------------ Reporter: luminans@… | Owner: stromnov@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.2 Resolution: | Keywords: Port: opencv | -------------------------+------------------------ Comment (by luminans@…): I tried several older versions of ffmpeg (http://ffmpeg.org/download.html) before opencv 2.3.1a (r 86729). I think port install the new version of ffmpeg. Is there any way to specify the particular version in portfile? Or, did I install ffmpeg in a wrong way? -- Ticket URL: <https://trac.macports.org/ticket/37314#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS
