Okay, so I compiled ffmpeg with those flags:
/configure \
--prefix=/usr \
--shlibdir=/usr/lib \
--disable-static \
--enable-debug=3 \
--disable-optimizations \
--disable-stripping \
--enable-gpl \
--enable-gnutls \
--enable-libass \
--enable-libfdk-aac \
--enable-libfreetype \
--enable-libmp3lame \
--enable-libopus \
--enable-libtheora \
--enable-libvorbis \
--enable-libvpx \
--enable-libx264 \
--enable-libx265 \
--enable-nonfree \
--enable-shared \
--enable-x11grab \
And I cmake'd my program with -DCMAKE_BUILD_TYPE=Debug
-DCMAKE_C_FLAGS=-fsanitize=address, but I still only have this debug trace:
==17320==ERROR: LeakSanitizer: detected memory leaks

//First step (that is practically always sufficient)
is to find out where exactly (!) the memory was
allocated: We all know that it was inside mem.c
but the important question is what called
av_malloc().
Either use a static binary or use
--disable-stripping for a useful debug build.
