>Description:
"multimedia/ffmpeg" and "multimedia/ffmpeg010" both include
"libavutil.so.51".  This can (and has) confused applications that need
the older "ffmpeg010" package, but also have "ffmpeg" (v1.0.1) installed.

When such an application asks for "libavformat.so.53", the linker finds
it in "/usr/pkg/lib/ffmpeg010/libavformat.so.53".  When subsequently
asked for "libavutil.so.51", the linker finds it in
"/usr/pkg/lib/libavutil.so.51".  The application fails, likely with
much complaining about inability to find codecs and spewing messages
with bizarre numbers which appear to represent addresses or offsets.


>How-To-Repeat:
On a system with pkgsrc-2012Q4 and an up-to-date "pkgsrc-wip",
install "wip/electricsheep-svn" (bringing in "multimedia/ffmpeg010" as
a dependency).

Then install "multimedia/ffmpeg" (or a package which depends on it).

Attempt to run 'electricsheep'.

Watch fireworks.

Also "ktruss -i electricsheep" and watch the shared libraries being
opened.
>Fix:
Is there a way to force linking against the full library version?
"ffmpeg010" has "libavutil.so.51.35.100" while "ffmpeg" has version
"libavutil.so.51.73.101"

Alternatively, pull up ffmpeg (v1.1.x) from HEAD as it has
"libavutil.so.52" which will eliminate the collision at the major version
number.

There may yet be a problem as libpostproc.so.52, libswresample.so.0, and
libswscale.so.2 still collide between the two versions of ffmpeg.

 Not tested, but the issue may be resolved if you move buildlink of ffmpeg010
 to top of the list, before jpeg.
 (rpath to ${LOCALBASE}/lib/ffmpeg010 will be added first).

 I made this change to "wip/electricsheep-svn/Makefile" and rebuilt.
 The "${LOCALBASE/lib/ffmpeg010/" library was searched first.

 Perhaps other packages that depend on ffmpeg010 or older versions of
 other libraries/packages should be check to make sure they reference
 those buildlink3.mk files before any others.

State-Changed-Why:
there's now fewer old versions of ffmpeg in pkgsrc and
they should all be able to coexist safely.
