Description

Hi,

trying to compile markad under Debian jessie (libav version 10.3), I had multiple errors in command/decoder.cpp regarding snprintf and various CODEC_ID constants not declared in this scope. I was able to fix the issue by including stdio.h and adding AV_ at the beginning of each constant.
Attached are the patches required to get markad compile, I guess that some more magic is required to keep markad compiling also with older versions of ffmpeg respectively libav.

Hope this helps,
Eric

the #ifdefs in lines 105-116
break compilation here with error, that CODEC_* are not declared in that context.
omitting these works fine here but possibly break it with older LIBAV versions.

Maybe adding some ifs which are testing the AVCODEC version like http://projects.vdr-developer.org/projects/plg-softhddevice/repository/revisions/8b7402a397bf460e25a75add8059aa2eb83709ee/diff/codec.c does it, are a reasonable solution.

File compile_vdr_markad_0.1.5pre compile_vdr_markad_0.1.5pre added

When compiling current 0.1.5pre source on Debian Stretch (testing) I do not get compiler errors in decoder.cpp (using 0.1.4 source I do), but I get linker errors with avcodec functions.
