Subject: [PATCH] Add pkg-config fallback for locating ffmpeg.
|
|
|
|
Audacity >=3.1.0 no longer links against ffmpeg, but instead dynamically loads
|
|
it. This dynamic loading mechanism fails to properly locate libraries outside
|
|
of LD_LIBRARY_PATH.
|
|
|
|
See <https://issues.guix.gnu.org/53591>.
