+From: local Buildroot integration
+Subject: [PATCH 1/2] build: fix FFmpeg AVCODEC component variable name
+
+FindFFmpeg.cmake records the AVCODEC component result in the
+FFmpeg_AVCODEC_FOUND variable.  The checks in libfreerdp use a differently
+cased variable, causing CMake to report AVCODEC as unavailable even after it
+has successfully found libavcodec.
+
+Use the component variable name provided by FindFFmpeg.cmake so that the
+MJPEG decoder dependencies are added explicitly.
