You can use the r1115 or r1123 build, which I posted in this thread
Again I patched r1123 to work with API version 66, as Avidemux 2.5 has not been updated for API version 67 yet.
Therefore the r1123 build should work Avidemux 2.4.4 Final too.
As soon as Avidemux 2.5 is updated to x264 API version 67, I finally will not
need to patch the builds any longer.
This will then break compatibility to Avidemux 2.4.4, which is stuck at API version 66 (as it won\'t be updated).
