From e1836b191b8ce956bebf050e664975f2e0f92325 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Mon, 14 Jun 2021 22:07:56 +0200 Subject: [PATCH] avcodec/libavcodec.v: Tighten export whitelist Currently every symbol (with external linkage) that starts with "av" is exported. Yet libaom-av1 has lots of functions that are not meant to be exported and start with "av1_" (I counted 1236); and libvpx has average_split_mvs. These functions are exported if one links these libraries statically into a shared libavcodec.so. Solve this by tightening the whitelist to "av_", "avcodec_", "avpriv_" and (as a special-case) "avsubtitle_free".
