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. + + As usual, if you have any question on this release or any FFmpeg related + topic, feel free to join us on the #ffmpeg IRC channel (on + irc.freenode.net). + + ┌────────────────────────────┐ + │ 🔨 API Information │ + └────────────────────────────┘ + + FFmpeg 2.4 includes the following library versions: + + • libavutil 54.7.100 + • libavcodec 56.1.100 + • libavformat 56.4.101 + • libavdevice 56.0.100 + • libavfilter 5.1.100 + • libswscale 3.0.100 + • libswresample 1.1.100 + • libpostproc 53.0.100 + + 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. + + ┌────────────────────────────┐ + │ ★ List of New Features │ + └────────────────────────────┘ + + ┌────────────────────────────┐ + │ 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. + + ┌────────────────────────────┐ + │ 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 |
