The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", ... |
|
|
|
|
FFmpeg 2.4 is mostly API-, but not ABI-compatible with the previous major release. |
|
|
|
|
This means that the code using our libraries needs to be rebuilt, but only minimal |
|
|
|
|
source changes should be required, as described in the section 'API Information'. |

|
|
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. |
|
|
|
|
|
|
|
|
|
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). |
