Heads up audio/video/graphics/multimedia/net/streaming port maintainers - ACTION REQUIRED

[Thomas Zander]

Hi,

if you maintain a port which uses directly or indirectly ffmpeg, i.e.
it links to at least one of

libavcodec
libavdevice
libavfilter
libavformat
libavresample
libavutil

please take a moment, this is important.

Shortly after the release of FreeBSD 10.1 I plan to upgrade ffmpeg to
the 2.4 branch and import the then-latest release from the 2.4 branch
into the head of the ports tree. Unlike the recent upgrade from 2.2.
to 2.3, this one will NOT be painless.
ALL the mentioned libraries received a bump in their major version
numbers, which means that they are not necessarily API compatible with
the 2.3 series. In particular, this means that several APIs which have
been deprecated several months/years ago(!) are really gone for good
in 2.4. One prominent example for this is the removal of
FF_API_CLOSE_INPUT_FILE in libavformat which breaks e.g. sox and
transcode builds. In most cases (like the mentioned examples sox and
transcode) a fix will be easy or even trivial, but you need to be
proactive and take a look at it.

I have prepared a drop-in replacement for the ffmpeg port which uses
the recent 2.4 release. You can download it from:
http://people.freebsd.org/~riggs/ffmpeg-2.4.tar.xz

Please check whether the ports maintained by you build and link with
this version and prepare a suitable fix if necessary.

Thanks in advance and best regards
Riggs
