examples with File recorder with CasperCG 2.1 beta 2

With build 3439 I got file recording working, here are some examples

with HDMXF 30-40-50 422 420 with stereo audio
ADD 1 FILE myfile.mxf -pix_fmt yuv422p -b 30000k (30mbit 422)
ADD 1 FILE myfile.mxf -pix_fmt yuv422p -b 50000k
ADD 1 FILE myfile.mxf -pix_fmt yuv420p -b 30000k (30 mbit 420)

HD mp4 with libx264 codec
options codec
-preset ultrafast,superfast,veryfast,faster,fast,medium,slow
-tune film,animation,grain,stillimage,psnr,ssim,fastdecode,zerolatency
-profile:v baseline,main,high,high10,high422,high444
crf range 0-51 (quality of the file)

ex.
ADD 1 FILE myfile.mp4 -vcodec libx264 -pix_fmt yuv420p -crf 32 -preset ultrafast -tune fastdecode
(about 4 mbit in HD)
ADD 1 FILE myfile.mp4 -vcodec libx264 -pix_fmt yuv422p -crf 25 -preset veryfast -tune fastdecode -profile:v high422

or
ADD 1 FILE myfile.mp4 -vcodec libx264 -pix_fmt yuv422p -crf 25 -preset veryfast -tune fastdecode
(the crf value controls the bitrate)

With libx codec you have to set -pix_fmt otherwise it defaults to yuv444!
