libopus-1.1 beta success

Hello, and a big thank you to all who helped put together the cross-compilation tool-chain and libraries. I usually have success cross-compiling on Fedora 19 to Windows 64-bit static executables (non-free version) including MP4Box, with -march=<our_cpu>. These binaries go straight onto my Avid and the desktop computer in the same suite.

I modified the cross-compile script to use libopus-1.1-beta instead of the 1.0.3 release, and it seems to build ok on today's release, so far. This has been done because of the advances Opus 1.1 contains over 1.0.

The software is tested with long video and audio encodes every day (mostly DNxHD, ProRes, dvvideo with 4:2:2 video at 50Mbit/s, libx264 and mpeg2video, and filters including deblocking, unsharp, scaling and noise reduction) and never gives trouble. We're very glad to have this tool at the heart of our transcoding workflow. We also use the tool to make burnt-in timecode copies for viewing much faster than the editor can; for automatically converting RGB 0-255 to 16-235; EBU R128 loudness compliance; for deblocking and noise-reduction on poorly-compressed sources etc., etc.
