+Subject: [PATCH] m4: fix local ffmpeg and avcodec function conflict
+
+Autotools miss avcodec function check.
+This is due to linker library list order, -ldrm is appended too early
+respect to -lavutil. This results in missing drm library functions for
+avcodec functions:
+- drmGetVersion()
+- drmFreeVersion()
+So these functions:
+- avcodec_get_context_defaults3
+- avcodec_open2
+- avcodec_encode_video2
+can't link correctly during check and they seem not to be present.
+Then macros HAVE_FUN_avcodec_* are not defined in mediastreamer-config.h
+So local avcodec functions conflict with real avcodec library functions.
+
+In acinclude.m4 file, swap $FFMPEG_LIBS and -lavutil if avcodec is found.
