Playback resolution is the problem and the hardware limitations will not
allow us to use the N800 screen as it is. That's a pity, alhtough I
understand the reasons for these limitations.
In fact the screen _is_ used in its full resolution. Well sort of. The pixel
doubling feature on N770 (Epson S1D13742 chip) and the generic scaling feature
on N800 (Epson S1D13745 chip) both use pixel interpolation when doing the data
transfer to its dedicated video memory. This means the result is actually
better then having half resolution as color of those additional pixels are not
same -> full 800x480 resolution is used. So basically you have better picture
without overhead of larger movie resolution. I agree full resolution would be
even better for some people with lot of disk space but IMO current resolution
is still good enough.
So I understood that the problem with mpeg2 is that the used resolutions
are too big to be transferred to the video memory. But mpeg2 itself
doesn't need much resources when unpacking. So would it be possible to
downscale the video before sending it to the video memory so the bus
would not stall. Then let the chip double/scale it for the fullscreen?
Of course it would be lower quality, but who cares if it would play!
I bought 4gb sdhc card and it works wonderfully with the custom kernel.
Now if I could dump some mpeg from DVB to the card and play it straight
up.. copying last nights tv-special or morning news takes less time and
planning than compressing and copying.
