Updated avidemux packages fix security vulnerabilities:
Avidemux built with a bundled set of FFmpeg libraries. The bundled FFmpeg versions have been updated to 0.9.4 in Mageia 3 and 1.2.7 in Mageia 4 to fix several security issues and other bugs fixed upstream in FFmpeg.
For the Mageia 3 update, additional patches from the FFmpeg 0.10 branch were added to fix a use after free in matroska and integer overflows in lzo.
