Subject: Revert "gst1-libav: switch to unbundled"
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=07415ad214373c787962a1479514739045916001;p=buildroot.git

Revert "gst1-libav: switch to unbundled"

This reverts commit 5dcb8aa0ba46e16b929c7c7fc9cea2d6c26201f4.

This patch re-enables the usage of bundled ffmpeg code because
gst1-libav 1.14.x is blocking the bump to ffmpeg 4.x.

A fix to build the bundled ffmpeg code on arm/aarch64 was added.
