XCD + hardware support: someone knows?

[jkwarras]

Hi,

Juyst wondering if someone around here knows if XCD will ever be supported in hardware players. I don't know if any of current mpeg-4 hardware players support it, but as i think is based in VCD (in some kind of way) it will not be very different to implement (just guessing, i don't know anything about it). Obviously there will be aproblem as many people use it to store mkv or ogm, that will also have to be supported, but that's another question :)

I don't really think it will happen, but we can dream, or not?
:cool:

I think only very few people actually uses XCD and it's only hack.
How many people outside Doom9 forums have even heard about XCD?

So just forget hardware support.

Just my opionion...

xcd is not a hack: data is stored the same way as on vcds (mode2form2). and as most players already support vcd (as jkwarras already wrote) i dont think it should be that hard to support xcd on standalones...

Mpeg4 video in mode2form2 is not hack? Well to me it is...

Maybe some small crazy hardware manufacturer is intrested who wants to support every possible "format" but i really doubt.

No it's not a hack. To me a hack is not something that is uncommonly used, but something that is not intended for a standard. MPEG-4 is a standard, mode2 form2 is a long standing standard, using them together is definitely not a hack.

Most hardware MPEG-4 players don't support QPel, so would qpel be a hack by your definition? Most hardware doesn't support alternative formats such as OGM or MKV, so does that make those hacks?

But back on topic it would definitely be interesting to see some mode2 form2 support on hardware players; but first I think we'd need to talk about alternative container support because I doubt many people are using XCD with AVI.

Yes, i also think that the majotiry of users choose XCD + OGM/MKV.

BUt as Gaia said, i also believe that most manufacturers will never support "strange" things like XCC, even if we know is not strange at all, but for them, is just not so "universal" to even think in supporting it. But is based in VCD (mode2 form) and is an standard, the implementation should not be that expensive. Just guessing:rolleyes:

try to search around in the hardware forum, there are already some posts about hardware players that support XCD!
the main problem with that it seems are the alternative containers, as they arent supported most of the time :(

check out the xcd faq as it will tell you that using OGM or MKV doesnt really help with scratched XCDs anyways...

to make sure that the files will still be playable you will need to make the mpeg-4 streams error resistant! read more about this here (http://forum.doom9.org/showthread.php?s=&threadid=65646)!
it seems that the mediatek chip is already able to play such error resistant streams (but i dont know if it does it bugfree)

Really? That's good to hear :)

I know. I have some OGM XCD that doesn't play as it's damaged. But i use OGM (and now MKV) because on my PC (Pentium III 800Mhz, 320 RAM) an AVI XCD plays jerky with every player, with no postprocessing and whatever directshow filter use, and OGM/MKV plays very smooth.

I've already read this one but i didn't know if it was talking about a specific hardware or only a theoretical future aplication :D

Thanks for the info. Hope it wil be possible to see those things in a near future.

and these error recovery tools are already also supported by some hardware players (which use the mediatek 1389 chip, like the gran prix, elta 8883...)!!!

Oh my God! This player is awesome! :D Can play Avi in XCD, that's a cool thing to hear. I hope someday MKV/OGM in XCD will be suppoted in standalone players ;)
