Bug#623682: libavcodec-dev: please mention the fate of CODEC_TYPE_AUDIO macros in NEWS or changelog

[Jonathan Nieder]

Package: libavcodec-dev
Version: 4:0.7~b1-1

Hi,

idjc fails to build for me:

| 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   -g -O2 -c -o idjcmixer-avcodecdecode.o `test -f 'avcodecdecode.c' || echo './'`avcodecdecode.c
| avcodecdecode.c: In function ‘avcodecdecode_reg’:
| avcodecdecode.c:235:33: error: ‘CODEC_TYPE_AUDIO’ undeclared (first use in this function)
| avcodecdecode.c:235:33: note: each undeclared identifier is reported only once for each function it appears in
| make[4]: *** [idjcmixer-avcodecdecode.o] Error 1
| make[4]: Leaving directory `/tmp/idjc/c'

Presumably this is due to a small planned API change, based on
libavcodec/avcodec.h:

| #if LIBAVCODEC_VERSION_MAJOR < 53
| #define CodecType AVMediaType
|
| #define CODEC_TYPE_UNKNOWN    AVMEDIA_TYPE_UNKNOWN
| #define CODEC_TYPE_VIDEO      AVMEDIA_TYPE_VIDEO
| #define CODEC_TYPE_AUDIO      AVMEDIA_TYPE_AUDIO
[...]

Please consider documenting this in the changelog or NEWS.Debian, with
a few words of advice for callers (probably that they should use
s/CODEC_/AVMEDIA_/ and the latter name has worked since version x.y.z
for some x, y, and z, I suppose).

Thanks for keeping the ffmpeg libs working nicely.

Regards,
Jonathan
