Also, the 770 has a landscape display. We have a portrait display. The
S3C2410 cannot rotate the image, so you would have to rotate every frame
in software, too!
Modifying a player to render the image to be rotated in the first place
shouldn't be hard, though perhaps any straightforward way to do that
would degrade cache behaviour? (A wild guess.)
Also, as re-encoding files spesifically for the Neo would be quite ok
with me, rotating at that point would be quite a workable solution also.
(I'll add that I don't necessarily expect the Neo1973 to play back
decent video and won't blame FIC if it doesn't, but I'll sure _try_
it ;)
The comparison I'm using internally - Pentium 100, just about will
manage that.
I do expect to need to pick codecs very carefully - there won't be much
spare.
Rotating internally may be the straw that breaks the camels back.
OTOH - going down to 12fps isn't _that_ visible on this size of screen,
and that helps a fair bit - as does reducing the sound bandwidth, or
going mono.
_simple_ audio codecs - such as NICAM 728 equivalent - which is 10 bit,
stereo companded from 14 bits, at 32Khz - may even be appropriate in
some cases - to reduce the load on the CPU, and trade off for bandwidth.
