Fix PR pkg/51113 reported by Joern Clausen.
ffmpeg needs texi2html features that can be not available in the version
provided natively by the platform.
While here also add a PRINT_PLIST_AWK to automa{g,t}ically print a PLIST that
need less manual intervention.
Bump PKGREVISION.
Prior to this change all USE_TOOLS were already present except "perl". That
blocked the generation of both man pages and HTML documentation.
Also handle the append of configure's --progs-suffix number to address
coexistence of multiple ffmpeg versions man pages (done via patch-doc_Makefile).
Bump PKGREVISION.

The most important new features are AVFoundation screen-grabbing support,
animated WebP decoding support, and Animated PNG support. In addition, many
exciting features for video streaming are also implemented, including MPEG-
DASH fragmenting muxer, HEVC RTP payload muxer, and UDP Lite support.
The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", just 2 months
after the release of 2.3. Since this wasn't a long time ago, the Changelog
is a bit short this time.
The most important thing in this release is the major version bump of the
libraries. This means that this release is neither ABI-compatible nor
fully API-compatible. But on the other hand it is aligned with the Libav
11 release series, and will as a result probably end up being maintained for
a long time.
Important API changes since 2.3:
• The new field mime_type was added to AVProbeData, which can
cause crashes, if it is not initialized.
• Some deprecated functions were removed.
• The avfilter_graph_parse function was made compatible with Libav.
• The Matroska demuxer now outputs verbatim ASS packets.
Please refer to the doc/APIchanges file for more information.
libavformat
• Icecast protocol.
• API for live metadata updates through event flags.
• UTF-16 support in text subtitles formats.
• The ASS muxer now reorders the Dialogue events properly.
• support for H.261 RTP payload format (RFC 4587)
• HEVC/H.265 RTP payload format (draft v6) depacketizer
libavfilter
• Ported lenscorrection filter from frei0r filter.
• Large optimizations in dctdnoiz to make it usable.
• Added codecview filter to visualize information exported by some codecs.
• Added silenceremove filter.
libavutil
• Added clip() function in eval.
Behaviour changes
• dctdnoiz filter now uses a block size of 8x8 instead of 16x16 by default
• -vismv option is deprecated in favor of the codecview filter
• libmodplug is now detected through pkg-config
• HTML documentation generation through texi2html is deprecated in
favor of makeinfo/texi2any
• ICY metadata are now requested by default with the HTTP protocol
release with all the great features committed during the three-month period
since the release of FFmpeg 2.2.
In this release, there are lots of internal overhauls that make FFmpeg a
more accessible project for new developers. Many important new
optimizations and features like QTKit and AVFoundation input devices are
committed. Contributions done by Libav such as a new native Opus decoder
are also merged.
Because of the increasing difficulty to maintain and lack of maintainers,
we are very sorry to say that we have removed all Blackfin and SPARC
architecture assembly optimizations with the cleanups done. If you are
interested in maintaining optimization for these two architecture, feel
free to contact us and we will restore the code!
Oh, and since this release, this modern-looking release note is provided in
addition to the old-style Changelog file, to make it easier for you to
focus on the most important features in this release.
Enjoy!
