[FFmpeg-devel] a64 encoder 7th round

> is there any reason not to use 5col mode?

Yes, size (0xa00 vs. 0x600 bytes per frame @ a charset lifetime of 4 
frames) and thus displayspeed :-) As already mentioned about the other 
modes i implemented as well, they all have their advantages and 
disadvantages. There are just different ways on how to display graphics 
on a c64. Some have more dynamic range, some have color, some have more 
details, some use grayscale.
Just imagine it is like displaying on a pc in gray8, rgb32, bgr24. 
Though one format might be enough there are still more, for a good 
reason :-)
You might have a look at pages like this, that describes a few (there 
are way more) graphic modes of the c64:

There are still new modes coming up (for one i am doing a converter 
together with Deekay and Crossbow who are mentioned on that site) but 
that still makes other modes not obsolete.

All the examples i saw so far didn't do any alignment here (inlcuding 
the codec howto in the wiki) I even was so kind to use the name of all 
fields for better understanding. But if it is the last issue found, i'd 
even align it :-)

Kindest regards,
