SOLVED Installing idjc from AUR, compiling fails. libavformat problem?

Question

I'm having difficulty installing idjc from the AUR. I'm not sure what could be causing it, although it seems like it might be an issue with libavformat. Here is the relevant part of the output:
gcc -DHAVE_CONFIG_H -I. -I.. -Wall -std=gnu99 -O2 -I/usr/include/FLAC -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -MT idjcmixer-avcodecdecode.o -MD -MP -MF .deps/idjcmixer-avcodecdecode.Tpo -c -o idjcmixer-avcodecdecode.o `test -f 'avcodecdecode.c' || echo './'`avcodecdecode.c

Answer 1

Yes, ffmpeg libraries dropped support for many deprecated functions and macros.  Either this was fairly recent, or the documentation has been fairly slow to catch up.
This change, however, is documented.  AV_METADATA_... needs to be replaces with AV_DICT_... and dict.h needs to be included.
This is an upstream issue and should be reported there, but I'll see if I can get a PKGBUILD to "patch" the problem in the mean time.
edit:  I was able to fix this issue with a single sed line in the PKGBUILD, but then new issues sprang up.  I fixed those, then yet more arose.  The entire package is written against an outdated version of the ffmpeg libraries.  This either needs to be built against those old versions, or fixed (rewritten) upstream.
edit2: if you don't need mp4 support, you should be able to disable this option and compile everything else just fine.  To do so you can use this PKGBULD hack in the build function:
./configure \
--prefix=/usr \
--libexecdir=/usr/lib \
--disable-static
sed -i 's/\(#define HAVE_AVCODEC 1\)/\/*\1*\//g' config.h
sed -i 's/\(#define HAVE_AVFORMAT 1\)/\/*\1*\//g' config.h
sed -i 's/\(#define HAVE_AVUTIL 1\)/\/*\1*\//g' config.h
make
adding the three sed lines.  This compiles fine, but again, you will not have mp4 support.
