# BASICS:
#
# The ATI W100 used by the C860 has 384 ko available.
# VGA videos requires :
# 640 * 480 * 12/8/1024=450
# Since 450 > 384, it can't play smoothly
#
# 16/9 is 640x360
# 3/4  is 640x480
#
# To get a decent framerate :
# 640*360*13/8/1024=364
#
# 640x352 is a safer default.
#
# With cccr=163, you can do video 640x352@25 fps, 500k, stereo 44.1kHz 64k vbr
#
# HINTS:
# Try to have audio sampling a multiple of 44.1 kHz (or 48 ?)
# Avoid xvid codec to get a better decoding, use Bvhq (b-frames)
# Do not rotate/crop/resample the video on the zaurus with -vop rotate=1 -vf crop:352:640 -af resample=44100:0:0, but do it during the encoding step
