High-color video playback on STE


Recommended Posts

Big quality improvement:

Same, in files, good for Steem or Hatari:

Just type in HAV filename after starting TTP.

 

Thanks to Douglas Little and his continued work on Photochrome.

This doesn't work on a Mega STe?

Yes, I thought about 12.5 fps playback, which would work on US or some other fast hard disk system. However, as said already, FAT16 filesystem is problem too. I used direct disk access with code in player self to get max possible disk reading speed. Main problem with FAT16 is that really fast loading is possible only in sizes which are multiple of disk cluster sizes - what is already used by 16 color AV playback. By 12.5 fps playback we need to divide loading of 1 frame in 4 parts, which will load in blank periods. With 320x160 it would mean dividing about 41KB in 4 almost equal parts - and it is just not possible to get proper loading sizes. So, only way is direct disk access.

That would mean partitioning card or disk so, that leave some space at end free - where animations will go.

It may work with Mega STE - when you attach CATA cartridge adapter with fast CF card + do little cut in machine . Sorry, no easier way,

 

It does play from the internal hdd, it plays slow, but more importantly, the video is all messed up. Looks like the common incompatibility you get between ste/mste. I see the same torn video effect from some demos run on mste that were meant for ste.

I did not say that it will play not at all on MSTE or STE - but is waste of time to try. No any incompatibility between STE and MSTE here.

Your hard disk is too slow for it. Additionally, FAT16 is too slow too. Under Steem whole data loading is very different. Nobody listen on technical details I write. To achieve this playback on real STE/MSTE many things need to be done in uncommon way.

 

There is recording from MSTE :

As I mentioned previously, the Space Ace video worked great on my 40mhz STacy. No audio of

course, but it played just fine.

 

Nothing else will though, some of them complain about screen size, and of course some just

won't start (well, one says "all is good" or "everything is okay!" or something like that, and then

quits out :) ). Those are expected though, because its not an STe and doesn't have the STe's

hardware.

 

Its not that we're not reading your posts, good sir, its just that with all your other impressive

achievements, we keep hoping for more! :D

The reason why Space Ace vid. worked is: it is short, and everything is preloaded before starting play self.

With videos longer than 5 sec, you need to load all data during displaying. And it is very hard case with hi-color, beause hi-color displaying occupies CPU complete. So, must perform loadings in blank periods. And it is only 1/3 of time with 320x200. With 320x160 is almost 50%, what is still not enough for usual hard disk speeds.

Sorry, but this is hunting of limits, and not only on SW side, but HW too - therefore works only with specific adapter.

Is this why there have been no New game patches?

I was thinking about playback on STE-s with UltraSatan - at 12.5fps .

There is a way to do it without repartitioning - at price of little slower AV file writing to it's dest. And before it you must defragment partition on which will copy AV file(s). This is a must because reading speed is crucial. And defragmenting is useful anyway, so do it now ! :)

Only 320x160 (or less) will work, more is too much for US. And not with every SD card. You need at least 1100KB/sec transfer rate - check with this:

First screenshot on page is done exactly with US + 1GB Kingston card.

 

Likely it will be ready after 2 weeks. In meantime Douglas Little and Cyg work too on improving conversion SW.
