<html><head></head><body><div>Hi,</div><div><br></div><div>If you are compiling the git master version of a plugin, you need to compile it against the git master version of the GStreamer core. We don't support mixing versions of the various GStreamer repositories. This macro was recently added, you could revert the relevant commit for this specific plugin if you want to backport it.</div><div><br></div><div>Olivier</div><div><br></div><div>On Tue, 2021-03-30 at 17:38 +0200, Guillaume Denis wrote:</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div>Hello,<br></div><div><br></div><div>I am new to GStreamer (and C) and I try to compile one of the base <br></div><div>plugin to learn (by modifying).
