Question for efika+linux users; is it possible to have no-glitches DVD playback under linux if efika had gfx card installed (for h/w decoding)?

Why i ask? If efika+gfx card are fast enough for dvd playback under linux, it would be also fast enough under mos, once drivers and movie s/w got support for h/w decoding.

well, afaik, hw decoding doesn't work under morphos, and even 600 mhz peg1/2 isn't fast enough to play dvd smoothly... even g4 peg 2 can't play it 100% smooth. (depends on dvd)...

Yes, but one day it might work. Who knows what MOS1.5 brings

But i think h/w decoding is avaliable under linux. If efika+gfx card+linux are fast enough for dvd playback, mos would be also.

this is just a theory... it could work, if it would use some hw acceleration... but... now there is no hw acceleration (afaik), so everything must be decoded by cpu... and cpu isn't fast enough to play dvd smoothly. as i said, with several dvds, also 1ghz g4 isn't smooth.

this isn't question of cpu consumption of the morphos/linux, but lack of the hw description. and for more, it's a bit problematic to connect a dvd-rom to the efika via ide... if you want to but efike to play dvds... then don't do so... wait for efika2, or so...

peg 1 should be enough to have smooth dvd playback. The problem with dvd isn't releated to cpu power but it's a software problem - mplayer on morphos doesn't have cache (at linux it's using some fork tricks and none wanted/had time/cared enough to reimplement that code in morphos version) so unless your dvd drive has good and efficient cache playback won't be smooth, no matter how fast cpu is. So there are a 3 possible sollutions - 1. testing a lot of dvd drives and selecting the one with a good cache, 2. implementing cache to mplayer, 3. buying a standalone dvd player

3 is actually the only option that makes any sense at all, and 1 is absolutely no option whatsoever for an Efika, but I thought we established this fact already, so whytf are you still chanting on this one?


- CISC

That settles that. CISC is one of our mplayer / dvd experts (ok slacker) so not possible. Efika is way underpowered for this application.

It's ruled out per definition since there's no reasonable way to connect a DVD-ROM to an Efika...

Sure it is, it works fine with anything that doesn't require a decent amount of raw processing power, or reasonably fast media access (both memory/bus and ide performance is abysmal by todays standards), ie; you can use it for lots of everyday tasks like various internet apps, office-like apps, playing low-demand multimedia (audio, medium sized video etc), low-end games, etc, but then again there are far more suited devices (not to mention cheaper) for all this...

IMO the Efika is not suited as an end-user product (you might have noticed by now), but rather as a prototype board for custom embedded devices (where the customer can tailor-fit the finished product to their needs), unfortunately this doesn't seem to be the direction Genesi wants to go with it (and besides the 5200 is really too crippled to have much of a chance to compete in this market anyway).

The 5200's integrated IDE controller does not support longer signal ways (read: signal integrity). It may be overcome by e.g. some PATA 2 SATA adapter. The adapter is connected directly to the PATA connector, it holds some logic and you can connect some SATA devices to it.
But while possible this is *nothing to recommend* IMO. The Efika is a really nice device, but no all purpose desktop computer and shpouldn't be treated as one. IMO the best inetrface it offers is the network jack.

Even if you were to overcome that it still wouldn't work as confirmed by someone else (I think it either was Geit or a friend of his), connecting a DVD-ROM directly to the connector (atleast as directly as you can (ie, adapter + homemade cable with inverted lines etc)) doesn't work properly; QED.

As amazing as this sounds it is true. Gerald, Raquel and I are in a taxi in the Lincoln Tunnel on the way to a meeting in NYC. We just read a few of the comments in this thread and we will post something about this later. Here is the word from Gerald: DVD works. MorphOS works. Freescale loves it.

Any questions? See EFIKA MorphOS video online at PowerDeveloper.

More later...

R&B + G

This is all great news. I can see it now. Car + Efika + MorphOS = Tech-My-Ride!

Great to hear Freescale love it.
