Re: [Avid-L2] faster Go Pro injest

Many complex codecs that require Quicktime decoding ("sample provider")
will always have terrible performance with AMA. It is utilizing the QT
engine (32 bit, single threaded) for tasks normally reserved for MC.
"Sample mapped" codecs (aka native Avid codecs) will perform better
making playback, transcode, and simple edits viable.

I have not tested large batch H.264 transcode with MC 7. Hopefully, it
is better than 6.0/6.5.
