From: Matt Oliver <protogo...@gmail.com> Was "[PATCH] libx264: Do not explicitly set X264_API_IMPORTS" Setting X264_API_IMPORTS only affects msvc builds and it breaks linking to static builds (although is required for shared builds). This flag is set by x264 in its pkgconfig as required since build 158 (a615f027ed172e2dd5380e736d487aa858a0c4ff) from July 2019. So this patch updates configure to require a newer x264 build that correctly sets the imports flag. The min version requirement of 158 is applied for msvc builds only. This is also removing the check for 'libx264 without pkg-config' which was left for compatibility reasons about 7 years ago when the pkg-config check was introduced by commit e06263ef1e0e172b2c76070b3dc739411af08e82.

Thanks, applied. Regards, Marton
--- libx264: Set min build version to 158 I'm submitting this patch on behalf of Matt with his permission. There was agreement that the >= 158 version requirement should be applied to MSVC builds only. v2: restrict the version requirement to msvc builds v3: fix unintended author change v4: add missing braces v5: fixed condition (again ;-) v6: hope I got it now.. v7: add comment about dropping non-pkg-conf check, re-add libx262 check Published-As: https://github.com/ffstaging/FFmpeg/releases/tag/pr-ffstaging-30%2Fsoftworkz%2Fsubmit_x264_api_imports_matt-v7 Fetch-It-Via: git fetch https://github.com/ffstaging/FFmpeg pr-ffstaging-30/softworkz/submit_x264_api_imports_matt-v7 Pull-Request: https://github.com/ffstaging/FFmpeg/pull/30 Range-diff vs v6: 1: 47843fb51e ! 1: 3baec48834 libx264: Set min build version to 158 @@ Commit message So this patch updates configure to require a newer x264 build that correctly sets the imports flag. - The requirement for 158 is applied for msvc builds only, - no change is made for all other cases. + The min version requirement of 158 is applied for msvc builds only. + + This is also removing the check for 'libx264 without pkg-config' + which was left for compatibility reasons about 7 years ago when + the pkg-config check was introduced by commit + e06263ef1e0e172b2c76070b3dc739411af08e82.
