|

FFmpeg 2.4 is mostly API-, but not ABI-compatible with the previous major release.
|
after the release of 2.3. Since this wasn't a long time ago, the Changelog
|
||||||
This means that the code using our libraries needs to be rebuilt, but only minimal
|
is a bit short this time.
|
||||||
source changes should be required, as described in the section 'API Information'.
|
|
||||||
|
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).
