|
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'. |
